Wow.. I've used literally dozens of B&Btriflo products and they're awesome! I'm sorry to hear you've had problems with them. I've never had a problem in over 12 years of different systems including some custom fabricated systems I had made for my e46 M3 race car. I'm sorry this happened to you. Their product is outstanding and second to none in quality. Only reason I dont have them on this car is because I wanted a different sound. I hope they make it right for you and I hope you don't always feel that way about them. However, they cant win over every customer.
::MODS:: this should be moved to vendor/manufacturer reviews. :-)
