your not a hypocrite you experimented like i did and found the result wasnt what you expected/wanted. i ran a 3 inch magnaflow cat w/ straights b4, loud as hell but sounded good. then i got the ticket and put the fart cans on there, believe it or not down low to about 3k it sounded v8ish, but after that it had the monotonous 4 cylinder tone that was annoying at high speed cruising. if i had a 5th gear it wouldnt have sounded bad, but we all know an a4ld just doesnt have another gear. ive done many combinations on the exhuast and wound up catless cuz its hard to run a cat when burning a qt of oil every 1000 miles, needless to say when i rebuild im def putting on the cat to reduce noise and clean up the idle/reduce pulsation. i will be running a duals setup on mine if i end up running a twinturbo setup on my trk, and an xpipe/hpipe may be used depending on what i come up w/. if im running one large turbo ill be running a large diameter pipe and singling it the whole way. ultimately for boost functions i prob wont connect the two pipes but may be interesting to test in my future builds.
