Based on this, I had designed an exhaust system for my old GP where the pipe from the headers to the cats was 3", and after that there was a balance tube, and behind that the mufflers and tailpipes were 2". Any larger would have been a wast of money. I still can't figure out why the dual on the V6 would be a drawback though. The physics are the same, right? I mean, you can't change the laws of nature. Does the increased flow somehow reduce the scavenging? Call me confused, I guess.
Hey, I also read something about the cooler thermostats causing the computer to read the temp incorrectly and therefore force more fuel into the mix. Supposedly, this wastes gas, and isn't good for the motor? Can Anyone shed light on this?

iRocco, you are a car guy. I agree with you on the whole physics and math. But in the car world, trial and error is always the best way. You can do the dual pipes with a H pipe to balance the pressure before the cat and do 2" behind. Just that from trial and error, you can do a single exhaust and accomplish the same thing. Exactly like the Supra principle I stated earlier in the thread. I just say that you should not do that exhaust from experience. Even the import V6'* use a single tube, just because it doesn't matter. You will just add weight and expense for no reason. But noone is stopping you. Give the dual pipe system a try, then do the single and do your own comparison. Pipe is cheap if you do your own welding.

Sounds like a new diet plan there... Hats, high in fiber, low in fat.
Anyhow, thanks for the feedback. I'm not doubting anyone here, just trying to get my mind around the concept.
Right now, I am considering a high flow cat and 3" pipe with high flow mufflers. Can you guys recommend specific parts?
Thanks!

Check out Domestic Performance'* website (DP). They have a decent (and the only, I think) selection of ram-air hoods for bonnevilles. They are expensive, but each is custom made to your liking. www.domesticperformance.com

LMAO. Dust indeed. DP has some problems yes, but I still hear from a lot of satisfied customers. It all depends on what you're getting and when. I know it shouldn't but what can you do if they the only ones carrying what you're looking for? For example, I'm looking for lowering spings. They the only ones I can find that make them to fit my car, unless I want to go directly to a coil spring company and spend 3 times as much, if they make it for me at all. I don't want to change the nature of this thread, even if it is old. Talking smack on DP is beating a dead horse. If there is no major time rush, give DP another chance.

Please don't dig up old topics that have no real meaning.
www.INTENSE-racing.com has PCM'* now.
This is REALLY old.
