I have a Magnaflow catback system I ordered threw RRM, I didn't have time to do it myself at the time. So a friend of my dads owns a shop and put it on for me for some In & Out burger. He told me it was the easiest and best fitting catback he had ever put on a car. But if it's cheaper to get custom according to Amby and Drucea... go that route.

 

Yeah awhile back i had the greddy evo 2 exhaust. great exhuast btw. easy to install took about 1-2 hours the only real problem was gettin the bolts lose lol. but just wasnt doing it for me so now i got a custom flowmaster exhaust. its loud but nice rumble to it. and RRM makes really good products highly recommened.
