no i mean dual exhaust. like i will run the 3" down pipe then i will get a dual 2.5"+ all the way back from there, as i will not be running a resonator or a cat.

well

be aware it is not that cut and dry :)

You must modify the fuel tank. The fuel tank is towards the right hand side (when looking from the rear forward). Makes for a not to good a place to run the "other" can on that side situation.

well of course there is!

You can have the muffler BELOW the fuel tank! ;) Though just a word of warning. The muffler DOES get nice and toasty and I would not want it below some very flammable liquid ;)

depends

on a car that actually needs it (say a v motor or opposed H4). I can see 2.5 Inch dual exhaust being just about right.

In our cars with 1 turbo (7m) single would be more efficent. On the 1jz I can possubly see TRUE dual exhaust from the turbo out being more beneficial but without running numbers it is a best guess.

yes but i dont want to get a echuas kit. i can get a custon ss for cheap. i know a guy that works at a muffler shop and he will give me a great deal. so i was just wondering what would be best. i think i am going with a 3" single. not ctas or resonator. i will go from the 3" down pipe all the way back.
