Is the thermal a good exhaust?

 

It has good diameters (breathes well) and has good fitment. I believe later models havea nice feature in that the tips can be adjusted in or out so those with USP rear don't have these things sticking out real far.
The sound is loud for my tastes, but I think it's a good looking exhaust that works well. They have both the street and the race, with the race being the more open and louder of the two.
Good exhaust, I think, just too loud for my tastes.
