I have a 2.5 in. true duel set up on my car. one pipe for each side, no x pipe or anything just two mufflers. with hedman long tubes.

i am thinking i was switch to single soon bcuz of the fact of the ground clearance.

so i was wondering how big should the piping be for a single set up, plus i want it to sound tough as well.

thanx for your help.

 

anybody? plz?

 

If your running a pretty tame setup a 3.0" single should be good.

 

well first you've gotta tell us your new combo, i know you built the motor so we need specs b4 we can help you with exhaust size. i'd go with a 3.5" minimum if you have a serious motor, i'm upgrading to a 4" myself so i NEVER have to deal with exhaust again, you cant really over exhaust your car anyways so go big!

 

okay sorry guys. had a long cold week!

so far the motor has:
bored .40
new eagle crank
sealed power rods and pistons i think 10.25:1 or something like that
lunati voodoo .504/.525 lift cam w/ 110 LSA
built heads 2.02/1.60 manley valves. i dont know what cc they are but the are decked alot! im almost in the valve.
edlelbrock RPM air gap intake
and planning on holley carb.
MSD

???

 

In all honesty i would just use a single 3" system, your cheapest way to go is to buy a catback, I have flowmaster, but from what I have heard magnaflow is the best buy with the sound quality, build, and price.

 

i'd run 2.5" or 2.75" pipes that y into a 3" or 3.5" pipe, and either dump it at the axle with a bullet muffler (borla xr-1!?), or run it over the axle into a muffler of your choice. the over axle part is where you will spend the most money, the muffler shop across from the discount tire in kemah is cheap if you just want to get it done, his work is ok but its not mandrel bent
