Flowmaster. Go with the real deep old school muscle car sound vs. the ear pearcing raspy snap-crackle-pop sound of many others. JMO!

Check out the sound clip in my sig...

What is the Stock exhaust size? Another thing I do not wanna run into is tuning issues. Even though no one has reported where the aftermarket cat-backs threw codes and a check engine light. I like the MBRP but 3" may not come into play until the warrenty expires and when I do most of the engine upgrades then. Dammit, this sucks having to choose.

Stock exhaust size is 2.5 inches. Really the only decision to be made about 2.5 vs. 3 inch exhaust is the plans for future mods. From what I understand, if you are going to only do bolt-on type mods like CAI, Pullys, etc., stick with 2.5 inch exhaust. When you get into Cams, Super Chargers, Turbos, Nitrous, etc. to make big HP, then you will benefit from 3 inch exhaust. Going with 3 inch exhaust but not doing the big mods basically does not gain you much other than maybe a deeper tone. Also remember, you do need a certain amount of backpressure to get the most out of your engine which is why staying with 2.5 inch exhaust is not a bad idea at all. Good luck.

P.S. I went with a 2.5 inch custom X-pipe config with Flowmaster Super 44 mufflers and love them. Flowmaster now offers a full 3 inch catback solution using their 40 series mufflers that also sounds fantastic. Be sure to consider those as well.

Edrock, thanks. I will stay with 2.5" for now. Gonna go research Flowmasters now.

IMO you can never out grow a 3in when it comes to mods and it doesn't hurt anything other than a minimal amount of low end torque. You can very easily out grow a 2.5 system.

I agree. That's why I said it depends on the future plans. If he is eventually going with internal mods and such, by all means, go 3 inch. I'm not gonna go that far so I decided to stick with 2.5.

That's why I'd just cut in an x-pipe/muffler to replace the h-pipe and add pipes to replace the stock mufflers. Total of $300 and you can upgrade to 3" later if you need to.

My pockets aren't deep, can't void the warrenty. So I'm sticking with 2.5", once warrenty is gone. Its on like Donkey Kong.

In that case (budget reasons), you may want to go to a local muffler or performance shop and have them replace the resonators with straight pipe and then have them put on your favorite performance mufflers. That will be fairly inexpensive and sound great. Or, along the lines of what Toehead suggested, leave the resonators in place and just replace the stock mufflers with straight pipe and tips. That would be even cheaper and get a great sound. The only thing about that option is to make sure that will pass inspection and be street legal. Some states are more conservative than others and dictate that you have to have mufflers installed even though the resonators kinda act like mufflers anyway. Also, you mentioned voiding warranty. Keep in mind that no matter what exhaust option you go with, there is no getting around voiding your EXHAUST warranty (NOT powertrain or bumper to bmumper). But that is no big deal. Any exhuast option you go with would outlast the factory exhaust warranty anyway. Good luck.

If you go to a local muffler shop then yes your warranty on exhaust is probably renderd void. However, My GM parts guy says I can order the exhaust system thru him and let the service dept put them on and my warranty is still in tact. However, I have owned many new cars and never once did I have to go in for an exhaust issue so the exhaust warranty is not going to be something you would use anyway.

[fixxxer525]

Yea, the dealership also told me that too. If they install the exhaust system I want and it will not void anything. 82.50 for labor at Jimmy Johnson Chevy. Spending money on exhaust no problem its just when something happen(s) to the enigine. That's when I don't have the uncle scrooge type cash laying around.

So if I replaced mystock pipes with a 3" system (magnaflow)would I
actually be able to tell I lost some torque from driving (no dyno)?

Is there alot of difference in the tone of a 2 1/2 vs a 3" (magnaflow)"

I bought MBRP for my Duramax (this week) and prior to that had always used flowmasters and custom bent systems w/X-pipe in my other cars. I can say that MBRP was one that I was looking at for our Camaro and flowmaster the other. Having installed the system on my Duramax myself and hearing that MBRP Cool Dual systems for the Duramax was a nightmare an could be a pain to fit made me hesitant. I found a awesome deal on the exhaust ordered and from my personal experience it was very nice. From start to finish it took me a little less then 2 hours for the removal/ install and was no were close to being a pain. The instruction where a bit hard to follow an just ended up using my stock exhaust to guide me with some help from the instructions. With all that said MBRP makes some nice stuff I am looking at them in the future for exhaust on the Camaro. Between Flowmaster and MBRP I am leaning to MBRP because of the square tip and we have GFX on the car.
