Not a new Idea a good one but not new. We did our first set almost 20 years ago. I could not get any one to buy them in the kit market. Cost was the mane factor. I have a new side pipe with a removable muffler tube and have been installing them. At about the rate of eight sets a year. WE have all so figured a way to keep the external timp down to 178 degrees with an internal timp of 575. Our next trick is to pass the sound check at Laguna with 1300 HP If you can figure that one out keeping the side pipes. I would like to here about it. so far we have come up with capping the out lets and running 3" tubing to a large can in the trunk and putting six oval holes in the deck lid .
