Default B&B exhaust

For those that have B&B exhaust on their cars, is there alot of resonance in the car (coupe). I have a 1991 with a single cat.

Thanks

George

I don't have it on my car but my buddy has it on his 94 and there is quite a bit of resonance. The quality is outstanding and it does look sweet. In addition, he had it tested at Carlisle and produced 285 HP at the rear wheels. That's only with the B&B and a K&N. Now that's impressive.

I guess, if "thats" what you call it, but the exhaust sounds good to me, :yesnod: , is polished SS, and should last forever. About $1200-$1300. Been on 4 years.

The resonance gets old between 1400 and 1900 RPM. Very loud. On mine, it's louder inside the car than outside within that RPM band. I tried sound barriers (whole interior), new exhaust mounts all the way back.

The fit is decent (still have to twist the right muffler once in a while), and the quality is good. Very good looking exhaust and tips.

I ended up plugging up one muffler exit (just at the tip) on each side, this reduces the resonance to almost none. My plugs are removable so I can take them out at the track. Still, seems stupid to spend $1,000 on a cat back and drive around with it plugged up most of the time.

You might want to call 'ol Billy Boat, I have heard that the muffler has been re-designed (at least some models have been) to reduce this problem.

Good Luck with your choice.

Pete
