IIRC. 3.1's Don't have a resonator where as the 3100's do. that affects the sound right there. i could be wrong though

Correct. The 3.1 MPFI exhaust lacked a resonator. Just a cat and muffler(s).

 

I'll have to disagree with this. I've seen a few later model (92-93) 3.1Ls with resonators. I believe most were the single outlet exhaust.

For sound I'd have to say Flowmaster 40-series. For decent sound and GREAT flow, take a look at the Hooker aero-chambers. They are more reasonable in price too.

A bit raspy when cold but then it settles down when warm. i guess I'll put in a 40 series since Ive been looking for muffler

i was just saying, its not going to hurt anything to pull it off, tone is about all it does, maybe a very slight amount of backpressure...

i wound up going with thrush turbos, sounds deadly. :mrgreen: ill make a video soon.

My exhaust has glasspacks of some kind on them and they sound pretty good. Although I really want a set of flowmasters like 1LoudCutty has on his.

 

FYI for others, I have dual 40 series delta flows... No resonator and 2.25" catback..

 

It does sound suprisingly good...

I have the same set up with dual 40 series mine is 2.5 though it sounds good

When you/he say 2.25" catback you/he means? the whole Exhaust System right? if so where can i get it from? and does that include the headers?

Posted

"cat-back" means from the catalytic converter to the exhaust tips/outlets. Headers are not included in "cat-back"
