actually a single 3in into a crossflow with dual outs is more efficent that a true dual setup of 2.5 or less

talk about dumb u guys must not know much about cars u came with 205hp u got 290 hp tops with headers exhaust and chip 3inch exhaust ur a joke thats for motors with 600 and up hp u got no back pressure messing up that engine aslo the 456 too high runing rpms rofl that gear and the makes me laugh i would pay 1000 tops ur messing it up and i love chevys

6 options jet performance chip big difference

headman shorties, 3in pipe all the way to the muffler 2 1/2 in outlet gutted cat and also cuz its a camaro chevy riddin hot boi

how much of a difference does the chip make?

I bought my trans am 305 TPI for 3200 needed tires.. same engine. i got headers by edelbrock and flowmaster catback 80 series muffler. same tips as urs. SLP cold air and a high flow cat. why the he11 is urs so much louder?!!!!!! i dont get it . i have headers and exhaust not to mention the same muffler. did u take the cat off?

actually im hitting 110 for your information i dont think it stupid it call being smart. if you want check out the speedo by searching camaro z28 305. then tell me what you think

nice car buddy

actually a bit over 90

yeah, then it will top out at 70 mph. get rid of the chip, and you may get $2500. and you dont have the miles listed, im guessing over 100,000. good luck with selling it. i always liked the 3rd gens.
