Welp project "Quad Life" will be no more after Friday. I added the NPP exhaust and it is just WAY to loud, raspy and droney. I added the NPP in a box, spent another 45 bucks in fittings for the vacuum tap and it still did not work. SOO back to the drawing board again.
So I have now had, Muffler Delete back to stock, Borla Attak and back to stock and now NPP and now going back to stock.
One day I'll find the right combo!
Lol you sound like me, I went from stock to corsa, back to stock, resonated xpipe and round magnaflows, then to dynomax VT, too quiet so now I'm running xpipe and muffler delete. I've spent almost half the cost of an ipf supercharger kit on my exhaust lol
