Emailed D&T to enquire about a system for my TL AWD VRX. Got to give them a call tomorrow as they reckon they have a special on the system I am interested in :doubt: . Just wondering if anyone on here has a D&T system fitted or know of anyone who has one fitted. After some comments on improvements that the system has brought to the car, and the quality of the system. The photos on their site for the FWD models does look very good, but after some real world experiences.

Cheers

I don't like D&T because of exactly what you said. They make out their systems are custom and superior than anything else, when it's ALL talk.

Example: Got my car back from full exhaust job from another supplier and i didnt like how it sounded (very farty and too loud). Coz I was driving past I pulled into D&T and asked their opinion. I was pretty sure the resonator wasn't up to scratch. They told my my muffler wasn't good enough, for no other reason than it wasn't wot they use. They told me they'd use a particular muffer (one of their D&T ones) that was especially designed for magnas and to eliminate the farty noise. I saw the muffler as a standard D&T high flow muffler. They then asked striaght away 'when would u like to book it in?'.


I went back to the place that did my exhaust and he knew what I wanted, and fixed it.

Also have read of somebody elses account of a D&T system for their magna, and they weren't happy coz they replaced their almost 2.5" stock system with a 2.25" system. Go figure. Link to where I read it here (http://www.snapsport.com/mitsubishimagna.htm)

So in short they claim everything is super custom and are very pushy. That was my third time dealing with them, and each other time was no different.

well wheni called them on their website they said there headers were D&T designed, when in actual fact they are just pacies

kinda put me off

there are too many sharks out there that dribble crap and charge $$$.

Thought I would just change this thread a little rather than start a new one.

Rang them today and they quoted me $1050 for pacemaker headers and a high flow cat. They advised me to leave the rest of the exhaust alone as in their view flows quite well, only change it if I want to make it louder. This pretty much follows the advice given to me by R&D at Mits.

Rang another place that was recommended by some people on here and got quoted $870 for advance headers with a custom secondary setup. If I want high flow cat it will cost me an additional $290. This place told me that pacemakers will not fit AWD's as the primaries exit behind the transfer case and they require too much modification which will deter from the performace gains promised by pacemaker headers.

So I rang Emtech and they quoted me $650 for the RPW race headers for the AWD. So at this stage RPW headers seem to be the go. Just wondering if anyone with a AWD has had pacemakers fitted.

Ooooo my god....thats a turn up for D&T.

Still very steep though. You can get pacemakers from Phillcom for $400 pick up in SA. Not sure about their fitment to AWDs tho. Either way, should cost about $650 fitted. Id' be suprised if they didn't fit because they both use a long header and are a very similar layout to RPW.

Those RPW headers from Emtech won't be fitted though, that's pretty much what they cost from RPW.

As a general rule, I paid $1100 for pacemakers, high flow cat, (and since I was going this far) 2.5" to my existing high flow.

My research showed pacemakers to be the best bank for back. Advance headers I don't doubt on quality, but they're a short header design and press bent. RPW race are expensive (with slightly wider diameter primaries than pacemakers), but if it's true that your pushed to have those because of AWD, I guess you have no choice

True but as they require no welding or fabrication I was thinking of fitting them my self with the help of a mate.

Going to ring AAA and get a quote and find out if pacemaker do make a set for the AWD, or if their current header is suitable for AWD.

Try liverpool exhaust. They are the ones who make RPW's exhaust. But otherwise philcom and get someone else to fit them($720). Pacemakers wont fit, the RPW race seem to be the best bet for an AWD.

Cheers for that. I was hoping that pacemakers would. But it looks like RPW. Just hope the gains are worth it. Going to see if RPW have some dyno sheets and some actual pics of the AWD primaries and secondaries.

Well I can tell you how they go tomorrow. I pick my car up in the morning. I had some other slightly less professional ones but had clearance issues. However with the bigger longer primaries the torque increase made the car feel much lighter and you can go everywhere in 5th saving fuel.

I look forward to hearing your views on them.

This is exactly what I hope to pick up with my AWD VRX.:D

Have a look at HM extractors as well if you are looking for gains up high 3500+rpm.
They are VERY expensive but they are another option heres the link for there mitsubishi range of extractors

As i said they are very expensive but they have a model that specifically is designed for the AWD.

Just wondering how the RPW headers are going Greenmatt????

They are finally on. They had to be modified! The collector off the rear bank was fouling on the gearbox. So I dont know if this is a change with the TL or not but its not an easy bolt up. The exhaust place took them back to Liverpool Exhaust to check that they were the right ones and put them in the jig again. They definitely perform better than stock and have quite a bit of hiss at high rpm.

Glad to hear they make a substantial improvement. Hopefully fuel economy will be better. Hiss at high rpm? Hopefully this is just the headers scavenging properly.

What sort of finish do they have?? Pity about problems with fitment as I was thinking of getting some and fitting them myself.

Cheers.

for anyone that is interested to know. Euroaccord had RPW extractors on his old TJ Sports, and his expert opinion are that they are worth their weight in gold. high praise from him esp if you know his history with RPW....:D

The finish is a steel grey paint.

Greenmatt,

Has the note/volume at cruising changed from stock? ie. Is there any drone whilst cruising?

I cant really say as I got a high flow cat and 2.5" piping with a resonator put in to go with the Lukey LR2779 I already had but its not too noisy and doesnt drone. I dont think they would effect the note too much, just a bit more high frequency noise.

So you went with the longer header race spec then? Was that do to the fact the direct bolt up short header design is for a FWD only?

Yeah, the longer primaries give better torque with minimal if any losses up high. And the street are really not meant to fit.

Did they (RPW) give you any comparison between the performance of the two designs? ie. Is it worth the extra $$ to get race spec for a 3.5 FWD auto? (Even though you have the AWD...) I'm ask cause the difference in cost of the RPW (bolt on) v. Pacemakers will be very close if I did the RPW's DIY. (Pacey's and RPW race spec require welding which I'm not proficient at)

Way back when RPW were first trialing the race spec design they grabbed a car which had their street design headers on it and swapped them over. Without any other changes the car turned out more torque on the dyno. I'll see if the thread is still lurking around somewhere. This was over 2 years ago mind you.

I read in the RPW race spec is bolt on too.:think:

Is the Ceramic coating a must have? Cause that'll push the cost up to $1K.

Yeah race spec are bolt on (unless you have an AWD :D)

Don't think anyone has ever tested coated vs. non-coated back to back. It's obviously a Good Thing(tm), performance and longevity wise, but just how much of a difference it makes is anyone's guess.

Pacemaker Website claims that Ceramic coating drops emitted exhaust heat into engine bay temps by 110degF. And a reduction of 10degF (in enginge bay) equates to a gain of 1% performance of the engine. So by their logic (and assuming most engine bay heat is generated by the exhaust - :doubt: Probably not true of course) it could be good for UP TO an additional 11% gain on non-coated headers.

Something to think about anyway. Might be worth the extra $$.

No kidding? I'd be terrified if my engine bay was 110degF hotter than it is now :shock:

For what it's worth, I got mine HPC coated. Made the extractors alone cost $990. Pretty scary.

Did you have the flex pipe done as well? or just the pair of extractors?

Just the headers themselves. It was an extra $200 or so to get the flex pipe done.

Probably needed on the horizontal section more for the contaminants/moisture etc that might deposit inside and attack the horizontal section of exhaust. hmm...

This mod is going on my list I think...:D

Question to everyone with RPW Race Spec Headers...

Have you only HPC coated the Headers themselves or the connecting exhaust/flex section too?

And why did you make that choice? (extra cost for minimal benefit?)

And did you reconnect EGR pipe? Did this just unscrew from stock header and screw into race spec header?

BUMP!!

I didnt reconnect my EGR as I already had it blocked. As for HPC coatings, mine is painted. Im not sure I could justify spending the same again on a coating. Not many people have them coated. Mine are going well, the car seems to be getting better with time.

Just wondering what where the other headers you had on your car?? I take it from your comments that the RPW where/are an improvement over what you had. Just asking as I am also looking at the HM ones, as I want a rather easy bolt up system.

EZ Boy made them, they fitted fine apart from ground clearance(lowered) but there is a strange resonance as the primaries are separated for too long. They actually performed better down low but not quite as well up top (trade off of 1m long primaries) Now they sit in the garage, it would probably be a much easier job to get them working on an FWD as there is more room to play with. The HM ones are pretty damn expensive, even if you did have to get the RPW ones modified i think you would still come out ahead. Also the HM are a short primary design which isnt great for torque down low.

My RPW ones have HPC. Just the pipes though. I chose that because I could and I liked the idea of reducing temps in the engine bay - that battery gets hot enough as it is. My 3.0l doesn't have EGR anyway.

I only gained mid range torque but it was noticeable. There was no peak power change.
