Im inbetween myself rihgt now.... i have gotten my piggie pipes done and now im going to be running open exhaust all the way back to a single Remus Silencer. (model 70TD 4.02" if any1 was wondering) and what do u think the better route would be..... Meet the piping up just after the DP's and run a single 3-4inch all the way back depending on if there is enought room for a 4inch which i dont think there will be.... or do i run twin all the way back till just after the rear wheels then meet up right before the silencer?

Performance wise i dont see there being much of a difference. im just thinking to keep less drone i should run twin all the way to the gack but i just wanted to hear youse guyses input or if any of u have seen or done this your self.

 

props too you if you do the 3-4 in

 

What do you want out of it? If you just want max flow, put in 2 2.5in pipes, it will flow a TON more & still give you some ground clearance.

4in is fine, but there isn't a lot of room, if you are lowered at all, it's going to hit everything.

 

go with a 3.5" single all the way back.. you should get more flow than twin 2.25's. (combined area of the twin 2.25 pipes is 31.8 while the area of a 3.5" pipe is 38.5) plus the single 3.5 will look ***** under the car. It wont scrape much or at all either. I run a single 3" all the way back and have had no problems.
