well, at our local muffler shop here in town i got a 2.5inch straight pipe put in all the way to the muffler. took out 2 resonators and to cats, back pressures still nice, even if u add a turbo, kept same muffler tho. only cot me 90 bucks and he y'd the downpipe for me, tho u might consider getting a bigger one. any turbo upgrades gonna break ur waller, st or tt. but it may be easier to go tt. but before anythin, just make sure its runnin good. i have a 94 SL with a ram air intake and exuast, my next upgrades prolly goona be a 75 wet shot. but its whatever. (Single turbos or custom, just to let you no)
