This performance exhaust system was designed specifically for use with our Three-into-Two header, includes a front pipe sized specifically for connecting to a Motorsport 3-2 header Y-pipe, and has no provisions for retention of the factory pre-muffler or catalytic converter. This exhaust will work on 70-78 Z's with our 3-2 Header already installed (HEADER & Y-PIPE NOT INCLUDED). It will NOT work with our "Six into One" Header Systems (parts 15-6012 and 15-6013). For a 6-1 Header system please see 15-6309 below.
All performance exhaust systems, no matter the manufacturer or type, will be louder than the stock exhaust system. This is an unavoidable consequence of reducing back pressure and therefore increasing performance. This is especially true upon acceleration when exhaust pressures are at their highest. This aluminized system, with a "turbo" style muffler ("turbo" refers to the designed flow of the exhaust through the muffler, not to a turbocharged engine), is no exception. This type of muffler, however, was designed to limit the level of sound, especially when the engine is not being pushed. Therefore while it will be significantly louder under heavy acceleration, especially when connected to a header as opposed to the stock exhaust manifold, it should only have a pleasing "low rumble" tone during normal operation. Please call us if you have any questions.
For coupe models only. See Related Items for our 2+2 extension pipe.
Oval performance mufflers should be positioned at an angle for a proper fit on 70-78 Z cars. Note that for 8/74-78 Z's that still have the original bumper mounts, you will not be able to get quite this ideal of an angle due to interference, but a slight alteration should work fine. Please give us a call if you have any questions.
