i agree with torinalth.... go wet ........alot of ppl seem to have good luck with it....low 12 sec 1/4 times...... i have the bassani o/r X and most ppl claim the straight through muffler works better with an X ( baffled for the H ) i have mac cat - back and get alot of compliments on the sound but as far as quality goes it leave something to be desired ..... i will save my money next time and go with saleen bassani or the magnaflow so i have all SS exhaust ....no more aluminized for me

....................as far as the chip goes i dunno but i doubt it will work
