just peeked under my car and noticed that the system runs into just the one cat, the headers are welded on, after getting a catback exhaust i just was going to upgrade the lot
but whats my options as to getting a cat and extractors to fit, will i need a y piece fitted before the new cat instead of the weldered on headers
the catback is a redback and has a round muffler just before the tip and a middle muffler?
bit new to this stuff but is there any cheap way to make the catback louder??
