I'm running SSI exchangers. Interestingly, the car had a raspy sound even when the exhaust was completely stock. Still could be header related though, I suppose. On my current set up, as well as the original, each cylinder bank's exhaust pathway is separate until the turbine inlet. This is different from the Euro & late USA exhangers where the two cylinder bank's exhaust pathways merge into one after the crossover pipe.

I've recently had a B&B dual outlet exhaust installed on my 86. It's too loud for me. Is it possible to cap off the right side outlet? I tried stuffing up the passenger side outlet with rags and it sounded just right. I'd like to make it permanent as long as it does not affect the performance too much. I figure I'll leave the tail pipe alone and just block it off internally.

Please let me know your thoughts.

You might be able to passenger side muffler tip and weld a round plate over the opening. Then re-install the tip.

Jegs and Summit also have inserts that quieten the sound some. You might be able to pull one or both tip, insert the cones, then re-install the tips. A less permanent solution.

I asked B&B the same question and to my surprise they told me that there is no reason why I couldn't do that. They suggested that I might leave a half inch hole in the block-off plate so that in case my exhaust is brand new the tips would discolor evenly left and right.
I am impressed with B&B's honesty, I half expected them to tell me to just buy the single outlet version. I do love the sound of the dual system but it's just too loud for cruising and attracts too much attention.
It's interesting to note that my mechanic has a similar car with same exhaust and it's not as loud as mine. We think the difference is in the K27-7006 that's on my car versus the 7200 on his, that the larger exhaust housing on mine makes it louder.
