Need some quick exhaust help

**BLWNPontiacs** · 03-12-2012

So my resonator is rotting out, gonna replace it tomorrow...most likely going with a glasspack(still might go straight pipe, not sure). What size do I need?(length and diameter of glasspack and of straight pipe please)

Thanks guys!

EDIT: The car is a coupe

straight pipe is a no no. lol these engines sound like poop. get a thrush glasspack.

**BLWNPontiacs** · 03-12-2012

I know this, was still thinking of what I'm doing...so can you tell me what size I need?

**gtpeddie** · 03-12-2012

pretty sure this will give you some insight and such. lol ive never put on one myself so this is the best i can do.

So basically our exhaust is 2.25''?

**gtpeddie** · 03-12-2012

i know our tips are 2 1/4 but idk but the exhaust piping they look a lil samll

**ctracer** · 03-12-2012

i think 2.5 until it hits the Y and then it goes to 2.25. meh, i dont own your generation of prixs so....

**gtpeddie** · 03-12-2012

ill have to measure

You're useless!!! j/k

I tried doing a search but didn't come up with much. I just want to get rid of this leak, it sounds like ass...and I'm tired of it. The GTA is still in pieces(blower is on its way back from ATI) so it's annoying driving a car with an exhaust leak.

Does anyone have the length of the resonator? I can't seem to find it

**KeithGTP03** · 03-12-2012

I believe its 30" long

its shorter then the stock resonator i know that and you can get one at an autozone for cheap there usualy behind the counter so youll have to ask maybe

**gtpeddie** · 03-12-2012

some one on here has to know what the inlet and outlet size if for a 97-03 resonator! im pretty sure its 2 1/4" but i wanna be safe and make sure thats right

**BLWNPontiacs** · 03-13-2012

A few people on another site said this one fit perfectly so that's what I'm gonna slap on there.

a glasspack is just a cheap resonator. it will fall apart at a much faster rate.

get another resonator, or at least what is meant to be a resonator.

**gtpeddie** · 03-13-2012

well its only $20 i dont expect it to last to long what would you recommend?

**BLWNPontiacs** · 03-13-2012

I just put it on tonight, if you get it be sure to leave no exhaust pipe on the old resonator, the one I picked up JUST fit so don't hack off any of the intermediate pipe. I don't care if it lasts one year...it was $22 w/tax. It got rid of my exhaust leak, the car is whisper quiet...mission accomplished.

**gtpeddie** · 03-13-2012

leave no exhaust pipe on the old resonator, what do you mean exactly? and what size was it 2 1/4"?

**BLWNPontiacs** · 03-13-2012

Meaning when you cut off the old resonator don't leave any if the intermediate pipe on it, you're going to need as much as you can get. Make your cuts at the very edges of the resonator.
