Price: $397.87

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!

2+2 Owners: We now offer a separate extension for this exhaust kit! See 15-6067 in Related Items.

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 performance system, with a Sebring Spiro-Core 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, 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.
