Hey guys, I just got my 2005 BA MKII XR6T last fridayand this is my first post . Its a 6 speed manual and still has about 2 years warrenty. I am looking to put an exhaust system on it but need some advise. I was thinking about a a 3 inch system with the works including dump pipe ect, but would like to what effects this would have on my engine and car overall and what exacty a dump pipe ect does. My car has no other mods and all the only mod I want to do is the exhaust system but wanted advise if this system could stress the engine and void warrenty. Cheers!
