[QUOTE="hotcobra03, post: 11363139, member: 53096"] after stopping bye and listening to your car,,here are my thoughts... 1st,,your car was nice,,even in garage being hard to see.. you were in car starting it so i not sure what you heard,,but from outside it was very raspy when it first started up...the raspy noise only lasted a few seconds before sounding normal...but as car got warmer the exhaust sound changed,,,to me it sounded like knocking sound... after wiping my finger in tail pipe it only came up with water and light black sutt..nothing grimy black... the rear bumper had no signs of burning/blowing oil,,, your engine was very quiet,,even the injectors were quiet... i didnt like the shake that would come and go at idle,,,my guess is clutch change is the cause for out of balance feel...you said it was a specs but i dont remember style... when i was looking at fuel trims with predator...your trims were balancing 0+/-,,but i noticed that other o2 readings werent showing .... car has pulley/cai/tune...so it has to be from the tune,as to why those sensor readings werent there....with my set up it still shows all o2 sensor functions...so this was great to learn,,but would take some time to compare between cars as to changes in tune,,how often do you have side by side cobras to compare.... so i agree with you on mufflers could be causing wierd sound,,,,use the search function,,being 8yrs now i think you should be able to find enough info on how magnaflow lasts... i think mine were flowmaster 40american thunder II...GOT THEM THRU SUMMIT.. we got ours in march -03,,, so what was being shown in mustang mags is most had these parts for exhaust,,so thats why i went with bbk/flow with 2 1/2in pipes... i still have my stock system,,,if you want you can try catback to see if sound changes,,before blowing cash...
