corksport
Pro's
superior quality
looks great
best sounding exhaust (imho)
not alot of drone, if any (i dont hear any)
not bad price, if u get the combo.
Con's
cant really upgrade the turbo with the downpipe (so ive heard)
tips could rattle on the fake tips. (but i guess thats possible wit all exhaust's)
i have the downpipe and the cat-back with the stock main cat. i absolutley love it. no cel, no drone, and it sounds more like a "exhaust". the others sound too much like straight pipes, if you kno what i mean. i get complents on it all the time. and also the power increase is insane!!
hope this helps
