quick exhaust question
im doing a single turbo and currently have true dual 3 inch into 2 spintech super prostreet mufflers.
question is if i should just save my money and keep the 2 mufflers and tailpipes and use a y pipe to hook them up to my 4" downpipe or shoud i get rid of them and just do a single 4 inch... or does it really matter.
