Been ringing around getting quotes for cat back exhausts. One place didn't mention anything about a resonator so i assume they wouldn't put one it.
But another place did say i should put a resonator in coz they reackon the magnas sounds "tinny" with out one and a resonator gets rid of that sound.

Is this true or not? Are most people using resonators in their cat back systems or not?

Oh and the quotes ive got so far are around $350, does that sound right?

Magna's without resonators ... makes them sound like beasts !

Mine does, though it seems like my lukey isnt dealing with the job too well, sounds like too much airflow, so with the money you dont spend on the resonator you should put in to a real performance muffler.


Good luck

Okay i rang back the place that didn't mention anything about a resonator and they said they put a "hot dog" in. Which they think is better than a resonator. Personally i thought they were the same thing :confused:

most exhausts will normally include a resonator...

i had my resonator taken off with hi flow cat and cannon and it was the most DISGUSTING sound....sounds like a sick dog

sounded like a skyline on ide tho :gtfo:

i took my resonator out, 2nd one coming off this weekend, and changed the muffler to a lukey and it sounds tough

yeah put in a hot dog,

it is pretty much a resonator but wont hardly affect airflow at all, and will make your car sound way better

i have one in my car, and apparently it sounds pretty good,

also, will stop your car sounding like a lancer with a 3inch exhaust lol (u know that fart-like sound)


later :cool:

wooottevveerr magnas sound gay with resso taken off :bowrofl:

wooottevveerr magnas sound gay with resso taken off :bowrofl:

Well thats pretty much what all 3 exhaust places i rang up said, no resonator = bad sound

yeah i seem to be the only one who has good hearing lol

i gotta admit for the first week i thought it was the beez kneez but after that i realised how ****ed up it sounded

most exhaust places will describe it as a "bark"

how ****ed up it sounded

while we're on the discusion of f@$%ed up things, hows ur avatar, thats just wrong mate :nuts:

i dont have a ress on mine ad its loud but it sounds nice with a cannon ask any of the nsw guys that have seen my car its bloody loud but it sounds sweet as plus if you take out all of your ressys including your lil one over the back wheel thats the most restricting one there is on a standed system it gos down to a pipe size quite small so what i would doo is take that one out first and then get a cannon on the back and leave the one in the middle and if you like that sound then keep it if not you want more sound then id take the middle one out any exhaust shop could do that and just put a pipe with two flanges in there if you ever want to put it back on again if you dont want to put it on just stick a bit of pipe in there and get them to weld it up then your done

:badgrin:

i got one put in mine to reduce the noise which it didnt at all caz i had the hole in the flex pipe, now the flex pipe is fixed it sounds meaty up until 4000rpm then sounds like a fart... not happy but it can be left alone for the moment

middle one is what is crap

and big paul...yes my avatar is just wrong but u guys are the ones that have to look at it :badgrin:

i'm gonna have 2 agree with 4pleazn. they sound horrible without the resonator, although i think the muffler can also have a part to play in this, from the few that i've heard, (4pleazn, booya, Under8d, my mates 3.5 auto and about 100 lancers) it was the most annoying high-pitched rattle/barking noise, not the usual deep growl that most people love

my car runs a 2.5 inch cat back, hot dog witha 5 inch cannon no other resinators. I love the sound. It is way loud, but i am sure all that have heard will agree it sounds was tough

To put it simpily if you have a resonator you car will go quicker as the magna's need some backpressure to work well with standard tuning, you may get some more power if you have a reprogramable ecu, but i still had mine put back on. It sounded like a riced-up honda civic with the trattling through the exhaust, but some poeple like that so do what you feel it right. i have a 2.5" with standard cat, resonator and 2.5" redback. The redback cost me $150 supply and fitted. hope this helps everybody making the exhaust mods.

I say take every resonator out and put on a good mufler, but if you want a bit more power and a flame out the pipe during shifts punch the center out of the cat, (not very legal :cry: ) but fun for people behind you :badgrin:

when i got my exhaust put in they didnt put a resonator in and it sounded like a peice of crap. went in the next day and made them put one in. It sounded sweet as at idle without resonator but when revving it sounded like crap. It sounds heaps better now with the resonator in.

the question really is; excel/lancer sound or not?


because cars with no resonators on press bent exhausts sound horrible!

yep i agree get a ressonator or hot dog ive heard many cars with out them and they just sound like crap not deep at all just louder and farter

Aha, I agree with no resonators and a good muffler.

Setting off alarms is a novelty to the meat sound.

Whatever you say about the 3.5litre with regards to that fart sound, im sorry im not disillusional but ive had mates flog my car all way though first gear and I had a grin from ear to ear.

More 'raspy' than anything, but I think thats because the lukey is ****..

Ive got two small ones in my dual system at the rear. had one big one and it was to loud. got quieter when i did the dualies...

Back pressure? 4-stroke engines do not require and actually suffer from back pressure. You perhaps meant 'disturbed exhaust flow'?

Backpressure can actually help :P If you have extractors and the primaries are too short, which almost every magna header I've seen is then you can get exhaust running back up the headers as the interference intervals are wrong - small amounts of backpressure can help prevent this :)

Having said this, I'm not trying to say backpressure is good just that it has it's uses.

You mean, small flow-restrictions at the tail end of pipe would prevent the gases escaping the headers too fast hence create more continuing flow? In that case, it would be badly designed exhaust system... Even though "manufacturers spend millions of dollars designing the best possible configurations blaa blaa?
Tricky thing, the exhaust system. Unless it's variable in size, there will always be some RPM areas where flows are imperfect.
But backpressure it self, as a term belongs to 2-stroke engines and to them only.
