I have the greddy ti exhaust with helix dp and cd and I was wondering if anybody knows a good place where I can get them to professionally weld an extra 2 inches or so to my testpipe. The reason why I want to do this is because the ti exhaust is just about an inch or 2 xhort of the rear bumper, thus it causes black soot and shit to build up. Gimmie a pm if you can help me do this please, thanks
