No not a bad roll. Theres different types of fiberglass rolls and titanium. Last time I used it it wasn't bad at all. Just aggravating as hell at times.
Thinking about wrapping my exhuast with titanium wrap. I always liked the added benefits of wrap. If it was a high dollar build I would get the head pipe ceramic coated inside and out but I think the wrap will be fine. Anyone wrapped their head pipes? Intrested to see who runs them and who doesn't.
