Im just wondering... how much of an improvement would a true dual exaust with headers have over headers a good y-pipe and good cat back??

 

Not enough(if any) to overcome the trouble you'll have with groundclearance.

 

Ya I didnt think so... it was just that there might be an opportunity to have a shop to do true duals... but i didnt think it would be worthit

 

i personally don't like true duals. They sounds nice but with some Pacesetters, ORY, and a nice exhaust system set up, will be all you willever need, expecially if you run 3in. pipe. True duals are good, but not worth the time and money. I know some people who do it, and don't like it, expecially if u delete the cats on a true dual exhaust, you will have no back pressure, and thats no good.

 

yeah my friend has a custom true dual on his 87 formula but he has to literally come to a complete stop before going over a bump or leaving a drive way

 

true duals become more beneficial when you have heads, cam, 90/90 intake...etc. With bolt ons only, there are still some gains over ory pipe but not as much. Yes I have them and at times clearance is an issue. But for the sound and the extra power, I think it's fine. If you are out to get every HP you can with what you are doing to the car, then yeah duals are the way to go. If you don't mind giving up a few rwhp's here and there for comfort and convenience then do the ory and cat back.

 

if you've got the money to shell out, and just want true duals, Bassani makes a true dual system for 4th gens and I don't think clearance is much of an issue. I don't remember how much clearance there was, but I think it was around 3 or 4 inches, and the clearance to my cat on my v6 os only like 3.5 or 4.5 inches.. But thats if you really want it and have the money, its probably just easier to have a single pipe for the performance you would see. I guess if you planned on making it a track car or something, but then you might as well make custom pipes..
