It has about 12 inches of pipe between the collector and the muffler. They quiet the car down ALOT. Open header was real loud. This is my buddy's 1967 camaro with an lq9 and a custom cam 230/240 dur. 617/607 lift. Here is the open header vid

Anyone know if taking my existing exhaust off and running a muffler off the header will effect my tune? Would the a/f ratio change much? Don't want any issues popping a motor on spray.
