Cat back exhaust
I know I posted elsewhere but I am so pleased that I have to tell everyone.
I have added cat back systems to other vehicles but what happened today almost leaves me speechless!
Forget the sound, which is wonderfully growly without being obnoxious, it's the added performance that grabs you!
I had the local Midas shop remove the entire stock exhaust system off my 2006 GTP in one piece so that I can simply reinstall it should I trade the car; saves cutting.
Then the muffler man replaced everything from the first flange after the cats back with 2 1/2 inch pipe, a round muffler in place of the resonator, a y-split just aft of the rear axle and then two mufflers with stainless steel tips rounding off the package.
Performance gains are really noticeable. At 2000 rpm's in low, a sudden shove on the gas pedal gives tremendous spin off both front wheels and instant acceleration that you can feel in your butt and back. 6000 rpm comes up quite quickly.
Even low rpms in fourth and a steady press of the gas provides instant response.
I am very pleased with the results though I had reservations when I started.
