price is unbeatable

The price and quality is excellent. I used these with 2 1/2 exhaust pipes just before the back tires. The sound was awesome and better performance. You will be the only one on the track that sounds cooler than the rest of the race cars. I was very happy with the product. Be creative with these mufflers and you will have the only different sound on the track that will knock other racers socks off. I would also recommend these on hotrods and muscle cars.

Only one end fits over the 3" pipe

I wanted to remove a section of pipe and slip these over existing pipe on both ends to passify the tech man but ended up having to use the band clamps on the one end. I didn't notice a change in sound or performance, but the track is happy, it has mufflers.

These are fantastic mufflers. The only issue I've seen is that the outlet flange isn't long enough to clamp turn-outs on, I had to weld them on. Really not a big deal, but clamps would have been easier.
