Availability Update:
The great manufacturer who has been making our headers and exhausts for many decades has decided to hang it up after a long career. We wish them the best. Before they left, they recommended another local manufacturer they knew and trusted. We’re getting all the jigs and patterns set up and running at the new place, and will have a new flow of well-made product on the way very soon.

Pre-Sale!
Most of our customers are reserving the header or exhaust they want ahead of time, to “get in line” to get theirs as soon as possible. We expect most to be already reserved before they’re delivered to us. To get yours reserved as well, just order using a credit card, and we will reserve your parts for you, and not charge you until the parts arrive here and are ready to ship out (Note: If you choose PayPal, they will charge you ahead of time, so we strongly recommend using a credit card). We hope to have great news soon! Thanks for your patience!

Includes:

(1) MSA Premium Exhaust System* for Stock Manifold

Description:
Get the flow and performance your Z needs to run at it's highest potential, without waking the neighbors when you come home late! This completely re-designed performance exhaust system includes a completely new FLANGED head pipe to connect to the stock exhaust manifold. The pipe-to-pipe (head pipe plus two long pipes) connections are all by way of flanges (pipes are 2.5" diameter). The "turbo" style muffler ("turbo" refers to the designed flow of the exhaust through the muffler, not to a turbocharged engine) is connected to the rear long pipe by a standard clamp. Includes chrome exhaust tip. This complete system replaces all pipes and mufflers from the exhaust manifold to the tailpipe. The long piping is aluminized for long life and corrosion resistance. The extra welding necessary on the head pipe excludes it from the possibility of being aluminized. This is not a factor, however, as the head pipe remains significantly hotter than the rest of the system, and therefore is not as subject to corrosion from condensation. For Federal emissions 280Z's. System includes no provisions for catalytic converter.

(1) Instructions

Note:
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 premium system, with a "turbo" style muffler, 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, it should only have a pleasing "low rumble" tone during normal operation. Please call us if you have any questions.

Installation Note:
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.
