im planning on buying a new header and mid-pipe for my MP3, possibley the obx header and sls mid-pipe. i already have the JIC titanium exhaust and i was just wanting some input on the header and the mid.
There is a TON of info on the OBX by doing some searching...and there should be a fair bit of info on the SLS as well (if that's not satisfactory, just search for the MAM midpipe which has a ton of feedback).
