Well im pre-spending tax return money right now and came across a question. I want to get LT headers and an O/R midpipe but they are different brands. Im looking at MAC 1 5/8" HTS coated LT headers w/ a shorty SLP o/r Xpipe. Will the 2 pieces fit along with my american thunder catback already on the car? Any different parts you guys would recommend or is it fine to have 3 different brands for the 3 different parts of the exhaust (MAC + SLP + Flowmaster) Ill be getting around $750 back and i'll probably be paying someone to do the install since i dont have the tools to drop the K or work with the car so try to keep price around $600ish total.
