Daniel,
Take you Bubs off, clean the ends real good and just run your exhaust headers open if the Bubs aren't loud enough. Remember the TT pipes from days of old? They just dressed up the ends of the headers. For God sake, buy a used hearing aid to make the Bubs louder. Loud don't mean fast. I drilled some $1 speedy pipes from ebay and they are plenty loud - loud pipes don't save lives, loud valves do!
Ride It Safe,
Dennis
