Re: Exhaust
If you want your turbo to spool fast,you need a straight through style muffler,A.F.A.I.K., Flowmasters are not straight through design. You dont need back pressure.
But, a straight through design is louder, so if you want a quiet straight through type muffler ,get as big of round you can find & as long as you can possibly fit.
IMO, an exhaust system w/no muffler sounds like A$$, & other think the same way,for the most part,plus,if you got cops that are aching to give tickets for being too loud,then do not run w/out a muffler.:2cents:
