...ive been reading and ALOT of you guys are running spintechs. i was wondering what series/model you guys were running. i have to get my exhaust re-worked to pass inspection (damn pa inspections!) and i was thinking about a 2.5 inch y pipe into a 3 inch high flow cat, back to a single 3" in and dual 3" out spintech. thoughts? im looking for something loud and powerful to get the neighbors to know im home late at night, but i also want something that is not ear jarring loud at crusing speed.
