Ok, need to get rid of my DTM exhaust and really quick...way too loud...and also I've got 2 1/4" piping down there, so I'm thinking get either 2.5" or 3" piping due to the nitrous shot going in....gonna get a magnaflow racing series muffler to replace the DTM....opinions?

Don't go over 2.5" or you loose too much back pressure.

3" is going to be louder.

It'll open it up nicely for spray/turbo.

I'd say do it all at once unless you wouldn't mind driving around with an even louder exhaust.

fastvtecCL

you are right it's going to be alot louder !!!!

lowboy

that is going to be loud as hell and when u run ur car without the nitrous ur going to be slower than u are with the exhuast u have now becuase of no back pressure

just decided to do the 2.5" piping. I also just orded a DC sport ceramic header, new fuel pump, and new spark plugs....which should all be coming in next week.....SWEET!!!
