    thanks man. That was taken last september after a full day of detailing it. I have a 3" in my car and it is LOUD when uncapped. The whole car shakes and rumbles. I only open it up at the track/shows/cruises etc... My exhaust is loud enough.

    same here but when I get the $$$ I am going to add on the electric.
    Manual will do just fine till then. The guy that welded mine on, welded the bolts on and put some wing nuts on it. Easy and fast to cap/uncap it. Have it put in the I pipe right b4 the exaust goes over the axle (on the right side of your car in front of your rear wheel)
