Anyone ever fit a set of Sperry headers with a GTAM side pipe on a S3 Spider? Because that's 100% happening rather soon, unless you tell me it's a terrible idea
sounds like you are building a race spec motor if you are dumping out of the sides with gtam shorty resonator... :-)

sperry's are more race spec due to there 4-1 optimized for higher revs rather than the more street oriented 4-2-1. you pay to play if you plan on your motor living from 5-7.5k
