          Kooks exhaust

          Great Product. Kooks takes great pride in their products. It shows in their design and construction. It's always a great fit

          1 3/4in Kooks LT Headers and 3in catted X-pipe install

          The headers are not an easy task for the DIY guy I had a speed shop install them. They are very nicely constructed and awesome looking. The fit in some areas are very tight I can feel through the body, a little rubbing going on at times. I believe its coming from the lower front brace where the header exits it barely clears by an 1/8 of an inch. They come down very low, so you have to careful with them speed bumps.The sound was extremely surprising, my Kooks set up is combined with a MAC stainless cat-back I was expecting it to be annoying loud at idle, but it is the total opposite, surprisingly the car is quitter than before at idle? You would never imagine that my car has a full LT Header exhaust system. At WOT it sounds monstrous, very angry! After a re-tune I also gained over 40rwhp/32lbft on a conservative tune with 91 octane. Overall I am extremely pleased with the product

          Great X-Pipe

          Not a whole lot else to say other than it's a quality x-pipe to go along with the kooks headers.
