Evil-Bee-NH · 07-15-2012, 12:01 AM

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.

2010CamaroRS · 07-15-2012, 07:50 AM

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, 07:51 AM

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

TRC-SS · 07-15-2012, 03:47 PM

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.

600hp-lpe · 07-15-2012, 05:41 PM

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.

Evil-Bee-NH · 07-15-2012, 06:23 PM

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

2010CamaroRS · 07-15-2012, 09:10 PM

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

Duflar · 07-15-2012, 09:56 PM

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, 10:21 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.

Maybe i just like the sound of your voices?

TRC-SS · 07-16-2012, 02:57 AM

I even changed out my cats and o2 sensors and still didnt have any emission issues

FIRECAM · 07-16-2012, 06:03 AM

I put a set of Borla axel back on no check engine lights. WIth that said sounded great and no issues with inspection in NH. I have since changed my exhaust and have the axel back for sale if interested. Let me know

2010CamaroRS · 07-16-2012, 07:46 AM

worthless without pics/price lol

600hp-lpe · 07-16-2012, 10:51 AM

The O2 sensors (4 of them) are located in front and between the Catalytic converters(there are 4 of them as well. These are up front close to the engine - like 2' and 3' from the exhaust manifold.

The mufflers are all the way at the back of the car. you could delete the mufflers and run straight pipes and not affect the O2 sensors - it would be loud - the cats quiet it up a lot.

It will sound better IMHO with *some* kind of muffler, and you probably wouldn't get hassled when you need a sticker with mufflers.

I have the Borla "s" cat back system and love the sound..

2012-2SS · 07-21-2012, 11:04 AM

I have a Pypes Performance axle back system in mine. Its called the Pype Bomb. Its a muffler delete but has resonators eliminating mid rpm and cruising drone you can get from other systems. It was under $300 shipped to my door from summit racing. It comes with clamps but I couldn't get the clamps to seal so I just welded it on. It has a nice deep sound and it sounds awesome under heavy throttle but it isn't obnoxious and does not effect emissions.

Video of pipe bombs sound please.

J-ROD-210 · 07-21-2012, 05:32 PM

Look on youtube.com for exhaust samples,that's why I went with Cherrybomb extremes. $400 for the whole system,catback with xpipe and all. My favorite sounding exhaust are the Cherrybomb,Pypes and Stainless Works Retro Chambered. Good muscle sound on all three.Oh,and Flowmaster Outlaws too. You will not be changing anything on cats or sensors unless you get aftermarket ones.

2012-2SS · 07-21-2012, 05:35 PM

Here are a few:

Evil-Bee-NH · 07-21-2012, 06:57 PM

Well going with that muffler delete and installing the cherry bomb glasspacks if your at the Budweiser show in august you'll get to see and hear how it went.

Also thank you for all the information regarding the emissions and other information particularly the new hampshire people who know how obnoxious our emissions laws are.
