OH Yeah Foggy!! DO IT!! I took some great advice from Billy at TRT. It does "feel" stronger and seems to heat up quicker. I got the Kit from Summit ( DEI) It came with 2 rolls of 2x50 ' fiberglass insulation and 1 can of high temp silicone spray. I bought an extra can of sprayalso. First i painted the exhaust, then wrapped it and painted it again. A little tedious but not hard at all. I wrapped from the y-pipe flang back to the turbo, i still need to wrap around the cats and the y-pipe foward, but i could tell a difference. Some guys claim they build more boost at the line, but im trying to get my tunig dialed in before i go back to the track. GO FOR IT FOGGY!! ill get some pics this weekend
