Not so great, better, Awesome!

The TTI headers kick ***! I can feel the exhaust 10' behind the car, but I do have 3" exhaust from collector to bumper with chambered mufflers that are inside dia 3" as well! I highly recommend them, but I had to go from the stock automatic valve body to a manual valve body to be able to get the shifter cable to work right. It was too crowded and no place for the kick down with the TTIs either.

I also had to re-route the trans cooling lines to the "fender" drivers side, to get them to work. There is no room for squat but the headers, but boy do they work!!!
