Installing a flowmaster for my 300 hp 305 TPI

Lets just say ive spend over my budget for my camaro and dont really have that much to spend. SO in reality im asking u guys how much would it typically cost to install a flowmaster catback exhuast system. Any guesses welcome. I really dont want to do it myself. Its a single 3 inch to a dual 3 inch outlet.

Well u should do it yourself every sense there is a money issue! The installation is straight foward. U simply cut off the old exhaust( cut the areas that appear to give u the most trouble>>> over the rear axle for example) once every thing is off U simply bolt on the new (dont tighten any bolts all the way until U get a mock up of how the tail pipes are going to be positioned & that should be all.

Oh, I for got to say, the single in & single out flows better than the dual exhaust model!! The cost is about 200/300$for the set up.

I took mine to a local muffler shop and they charged me $100 labor to install the same system you have plus a 3in. Catco converter.Labor may be higher in NY.Hope that gives you some idea of what to expect.

I added a catco cat along with all new
2 1/2 " pipe and dynaomax muffler and I noticed a bit of difference, nothing earth shattering though. The headers are what did it for me!
