4" exhaust (LT1 or LS1)
4" exhaust (LT1 or LS1)
Custom 4" catback exhaust. Fits 93-02 f-bodies. Single, hidden tip, slash cut, Dynomax ultraflow muffler (stock location), and a Dynomax bullet muffler in the intermediate pipe. This 4" flows better than a Mufflex due to is strait thru muffler design. I picked up 3mph in the 1/4 with this exhaust over a Borla (with open plate). When I added the bullet to the intermediate pipe it really cut down on the noise/resonance.
The exhaust was designed by me and fits perfect. You will need to modify the area under the passengers side rear seat for the bullet muffler, but minimally. This exhaust did not rattle (hit) in my car at all.
The exhaust only consists of 2 pieces and includes all hangers and clamps.
One of the best 4" systems out there. Selling because I sold my car.
$300 plus shipping
