I have a slightly used Doug Thorley Pipe Bomb. Its a Y-pipe that appars to have cats but doesn't. It takes about 15 minutes to bolt on and gives you power that you can feel. It also works great if you have the Doug Thorley Headers. I loved this product but I took it off because I'm about to sell my tacoma. I'm in south Georgia if anyone is interested and would prefer a local pick up. Make me an offer. Thanks for looking.
