The ISP west site has a picture of the bellows with a side shot that shows the clearance of the OTT muffler its on the detailed view link.

Does anyone have experience on the quality of the ISP bellows?

I have been using the ISP OTT system with stock heat-exchangers. I did weld up some flanges to avoid using the stock donut seals.

I like it. I was worried about cooking the boot, but in daily-driving since 2007 haven't had a problem. A good state of tune helps keep the exhaust from getting crazy hot.
