My problem is that there isnt a huge selection for a 4dr cat back system. So I got all the parts hoping to get custom bent piping and Id be good...well come to find out that most(all) of the exhaust shops I have went to will not install or hang piping because they cant prove the headers and cat are state legal. So Im stuck with parts, exhaust still loud as heck, not wanting to spend alot of money on custom piping+labor, and Im not seeming to get alot of help from this forum which was the reason for my response. Im not asking how to install anything, I have no problem with that, Im not sure what to get with my setup and performance plans. Ive never had a car that was NA. I want to get an Apexi World Sport 1 or 2 system but I cant find them for 4dr.
Can I just get a coupe world sport cat back system and just extend the piping? Im not sure how much longer the piping needs to be from coupe->sedan. If you know the measurements of the coupe/sedan differenctial please share. THanks
