Ok so let's hear it!!!

[camaronewbie]

First off, this is a 2010 Camaro SS L99:

I took off stock exhaust, the resonater and mufflers. I went with a magnaflow tru x pipe (the free flow non resonated one) and straight pipes. Sounds good not that loud at all even at open throttle.

NOW:

Will there be an affect in gas mileage? ( in my opinion no, I still have the X Pipe to even the pipes out and balance the pulsing)

Will there be a loss of HP/TQ? (No right? Because again the X Pipe, and all the BP is created by the heads and the cats correct?)

Just did it today and also installed the Vararam Intake, Power Wedge, and super hips 8040 (91 Perf Tune).

Thoughts and opinions? I already know there are quite a few threads so please techy knowledgable mechanic guys respond

You have a L99 not a LS99. You won't gain much of anything

[camaronewbie]

No I'm not looking to gain anything at all, I know with these motors and the set up with cats/stock headers no exhaust can really provide gains. Was just simply curious to hp/TQ loss and mpg loss thoughts

[rebelyell22]

Nah, I don't think you will lose anything

[camaronewbie]

Yeah hat was my thoughts as well. Ok cool, thanks for the response!! It such a common battle on this forum lol

You won't gain anything from the exhaust....or lose hp or tq...the cai will help a bit as well as the tune...can you reduce torque management with your tune? If so you really gain from that.

What's your take on MpG? Should remain the same right? I'm using the tune to also remove the ANNOYINg AFM. It's driving me crazy and kills the fun of having this car lol

I will actually check into that, have never thought of that

You might gain a little extra mpg's because you removed those big, heavy mufflers.

People that have removed the afm have posted no real difference in mpg. I don't think it will change...yes the afm sucks ..tune that out

[camaronewbie]

Yeah I know removing the AFM will not help with much other than the annoying noise. All I can is add some shorty headers, gains are only minimal between 8-12 max HP but I'm in Cali

Can you go with hi flow cats?..im emissions legal with the shorties and hi flows..heres how they sound in the car....http://youtu.be/8FBbVde9z80

[camaronewbie]

From what I understand high flow cats are not emission legal either. Sucks.

[camaronewbie]

I read that wrong, wow that sounds good. What shorty and cats are you using? So you changed all 4 cats?

I have jba shorty headers with solo hi flow cats......the solos don't trip a cell and neither do the shorties.
