Got tune and cats removed today!
Mustang Dyno: Stock 343 TQ 356 HP
Tune 371 TQ 379 HP
Im happy with the results! Car pulls alot harder and on the way to the shop I bottomed out and broke off one of the motors on my cutouts so I did't get to dyno with both open.
BTW: the stock TI exhaust with no cats sounds awesome.....
How do these numbers compare to some of you guys with similar mods?
