    I don't know how it is in the USA, but here in Holland we can't have too many dB compared to the standard exhaust. Will this give trouble???

    It’s a chambered muffler instead of a bullet straight through race muffler so it will be quieter than a loud mouth 1 or 2. check out YouTube and search for vids. Just keep in mind that in person they are always a little bit louder.

    From what I hear SLP is about to go out of business. If I were you I would look at Hooker and Magnaflow.

    the powerflow took the dual/dual's place. It is a quiet system, but in my opinion not as good as the dual/dual.

    The dual/dual was the best catback ever made for our cars period. People may not have liked it because it was quiet, but after you start really modding H/C. it really wakes up. I can leave my house at 5 in the morning and not wake anyone up around me.
