3.0TH magna manual had twin 21/4" dual from rear axle with redblack mufflers

last week
pacemakers, high flow cat, and 2 new redblack mufflers(old ones had big rust ones in them)
noticeable difference in performance smoother rev range and more torque


today
above plus 3" mandral blend cat back to the dual mufflers
a even more noticebale difference

will have it dyno soon

note to redav GET THE 3" piping done asap

good stuff mate!:confused: but i'm a little confused, i lost a little bottom end with paccies and 2.5" system...... are you sayin you haven't lost any?

that's right NO losts


only gains

you sure its not 'seat of the pants' gains? i guess even a dyno test now wont give us a definitive answer....

hey sounds good, got a quick question...
is your CAT 2.5inch?
and are your mufflers 2.5inch?

note to redav GET THE 3" piping done asap
You've gone 3' from the cat back? I presume you're still going to dual 2.5' into the mufflers? Do you know if the muffler inlet / outlet's are also 2.5'?

Interesting.

Had paccies on my old TJ Exec dyno said gains, seat of the pants said otherwise.

Down low she lost a bit but it deffinately went better in the top end

ok this is what i NOW have

pacemakers into 2.5" hi flow cat - 3" Res - 3" piping - into 3" Y to dual 2.25" piping to 2 x 2.5" redblack mufflers with 4" tips

i have driven my car long enough to no how quick/slow it is and i can feel a noticeable difference but i can be wrong

Could it be that there was an increase throught the whole rev range, but due to the fact most of it was higher in the rev range it only "felt" slower down low? :P
