hi guys, im new , i was wonder how much hp dynomax cat back, pulleys , chip and a catco cat would give me? thanks

 

If you're lucky 10HP Maybe 15
Do a major tune up. Do a search for that topic & gain back that much HP for less $$.
Then do exhaust!

 

but i only have 46,000 miles on my car and my mechanic says that the car is in perfect working order so i dont think that i need a tune up.i think i will get the exhaust first. i also have silver racing stripes from www.3rdgendecals.com that im waiting to get in the mail anyday now. Camaro=
