I know every thing in a car is preferance and trade offs but I was wondering wich exhaust combination or kit is the best for a 2K mustang GT

 

whatever you think sounds the best is what's the best. i'm an SLP fanboy. i love my LM2s with magnaflow catted X. very deep and very loud. rumbles at idle and sounds like pure sex at WOT.

 

right now ive got stock headers and mac pro chamber and mac mufllers no cats no resignator yet its still street legal its sounds deep and loud but i want it deeper so i was thinking mac long tube headers wut do you think

 

yea, like you nailed it on the head by saying preference

youve got 4 answers on this site that are general consensus for catbacks

whichever you do,
if you can get LT headers, do that
if you can get an o/r pipe, do that

catbacks

not in any specific order

Bassanni, MagnaPacks, SLP's, Borla Stingers, some will suggest flowmaster or magnaflow
