  • Firebird/Camaro Dual Exhaust w/X-Pipe Idea

    I've been scheming again, trying to figure out a truly unique setup for the exhaust, or at least one that would sound bada** for not too much money. Here's the idea:

    1. First of all, for loudness, use no muffler and no catalytic converters. Have an idea to remove rice sound...

    2. As I suggested before, remove the bracket for the stock cat, cut the y collector at angle, run 3" pipe straight at angle past s-bend to I-pipe.

    3. Connect 3" I-pipe to 3" pipe coming from y-collector.

    4. Use a Y collector (3" inlet, dual 2 1/4" outlets) backwards to expand single 3" pipe into dual 2 1/4" pipes.

    5. Have a custom 2 1/4" x-pipe made by muffler shop for you and use it around I-pipe area before the axle crossover.

    6. Run both 2 1/4" pipes over axle and run one out each side of rear. Use whatever tips you want.

    The small pipe diameter (2 1/4") should keep from losing too much backpressure and allow enough space to run both pipes over the axle and the x-pipe should help remove the rice sound and give it a meaner tone. Any comments or suggestions??

    Also, instead of an x-pipe, if it is a problem to get or is not possible to use, you can buy two 2 1/4" in/out chambered mufflers after the y collector branches off the two pipes and just the 2 1/4" piping out of those, over the axle, and out the ends with whatever tips you want. This might be a bit harder though, but you never know how it would sound. :D

        well, that wouldnt be a true X-pipe set-up!! unless thats not what your looking for...also, compare the area of two 2.25" pipes, with a single 3", its too big

          A true dual will have the 2 exhaust banks connected only at the x-pipe.
