Installed my catback exhaust yesterday while most if not all of you wont much care for my selection it worked out awesome as far as im concerned. I went with the low line Pypes system with the M80 resonators. I bought my Cobra in Dec and it was bone stock and pretty much still is. I got to drive it for all of 3 days until I figured out I had a very Slight head gasket leaking on number 2 at which time I pulled the motor and heads and had everything checked and done several upgrades while it was apart. All the while of the series of upgrades done the noticeable improvement was the $461.99 Pypes catback system while Summit titles it race-pro and lethal titles it violater they are the same system. It sounded rather docile when the car was started while its loud its not too loud being the rest of the exhaust is still factory stock it feels like I've gained 50 horsepower literally. I've had mustangs for 20 years and had 20-25 different mustangs with an 85 GT being my first and the oldest model I've had from Foxbodies to new edge cars this is my first Terminator and modded all the cars I've owned. This is the far best gain I have personally experienced with such a simple bolt on. I am seriously excited now to see what a 2.9 pulley and X4 SCT that will allow me to drive the car before I have it strapped down on the rollers.
