they did a custom job for me when i was making my exhaust. good sound, nice growl but not enough to **** off your neighbors but throaty enough on hard accelleration. if you want it quieter the baffle is easy enough to install. i had a problem with the packing blowing out about 10 months after the install. one call and i had a new muffler in two days at no charge. top notch company to deal with.
