Exhaust Questions

[akdsmer]

If I was going to change the stock configuration (which I don't think I would) I would run a "super single", that being a larger diameter single pipe back from the cats. This would be quieter due to the two resonance chambers helping to cancel each other's noise. This would also be quieter, cheaper and fit better. I must be getting old, because I'm tired of loud exhausts, especially on the trail when I want the window/top down so I can enjoy nature. Those that share the trail with you would also appreciate it. Yes, my Mustang will be duals, H pipe and rather loud, but that's a musclecar. It's SUPPOSE to be loud and annoying.

Most dyno tests don't show much difference in X or H pipes, plus almost all the few ponies are at the high end. X pipes are expensive, or if you make them, a small pain in the arse. If going to duals, just stick a pipe in between the two at some convenient point and roll with it. If you need to drop your et's by .01 so that you can "be in the 11's (or whatever bracket your in)" then maybe the extra work for the X pipe might be worth it.

Search Hot Rod...or was it Mustangs and Fast Fords :confused: in the last year to find an interesting dyno test to determine the lack of improvement. Keep it stock, put your money into Huaneng Power International Inc. (HNP) and see what happens in the next 3 to 5 years.
