how did you measure the 0-60mph time?

 

i have a little computer that starts and stops 0-60. best is 4.9 i had a bvuddie with an 02 mustang gt his best is 5.6

 

i have removed my cat and just welded pipe in place coming right off the headers... with a stock intake and headers i have a magnaflow on the back (forget what they are) and it does sound pretty raspy in low rpms and when slowing down but when i get on it it is loud as hell and not very raspy... but then again i think loud as hell is a good sound...

 

that's cause louder IS better maybe a 30 dollar cutout would be the best way to go here

 

yes just cut the cat out or completely clean out the cat... unless your in cali just cut it out!
