Question for the Exhaust Informed. - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

So i'm looking to replace my stock mufflers with glasspacks but don't know if it will cause me to fail emissions. Does anyone know if it's to close to the o2 sensors or if the backflow will be reduced to much?

If you need to know the reasons the stock mufflers are god awful looking don't have the money for a rear diffuser and i'm looking for a less expensive way to disturb the peace then an expensive exhaust system.

axle back systems are relatively inexpensive...ive got the Flowmaster AT kit and it was only a few hundred....and 40 mins of time....its aggressive...yet more subtle than some other kits...well i added headers so...so much for subtle lol

2010CamaroRS · 07-15-2012, 08:51 AM

oh...and they hide well behind the stock valance

If your looking for cheap sound, then you will be fine with just cutting out the rear mufflers and either putting pipe in its place (muffler delete) or putting in the glass packs. Sound will be great and very cheap.

there are a lot of different exhausts you can get (axle back) that will change the sound.

Best bet is to go to a show with a lot of 5th gen's at it and listen to a bunch of upgraded exhausts to see which one you like.

already went to the RI show loved the exhausts have a friend with glasspacks on his *cough* intrepid look-alike camaro and they sound awesome.

but your all getting away from my question at hand on the o2 sensor location and the emissions in NH.

Why are you looking into putting glass packs all the way up front. You wanted to get rid of the trash cans in the back right.....either way you wont have any issues. I changed my whole system out with 3" piping and hollow tube mufflers. No issues

ur also a cop tim...im sure u could go open headers and still pass inspection lol

what i meant was no issues on emmisions....had mine probed this past may

From what I have heard as long as you don't touch the cats you shouldn't change emissions. Makes sense to me mufflers do nothing for emissions.

Evil-Bee-NH · 07-15-2012, 11:21 PM

See those are the answers i was looking for didn't really know where the o2 sensors were and i was far too lazy to go look it up.
