I picked up my 2000 T/A after installing the Prc stage 2.5 5.3L heads and MS3 cam. The car is an animal!!! Anyways 419 H.P. 362T.Q. on a Mustang dyno. I think the torque number is low but after 4000rpm's i don't care. Just a reminder this is with a LS1 intake and Catted y pipe with Flowmaster catback. A few more bolt ons and I am set!

Not bad number for the mods on the car. Get an intake and a cutout on that thing!

Just a quick note for you. We had a car on the dyno last week that we put a MS4 in that was doing 370 RWHP thought a Flowmaster. We opened the cutout and it did 405 RWHP.

WTF!?!?!? are you serious! i wonder what flowmaster has to say to that! and if they make a claim of any HP gain on their website or anywhere else. Ive known about how flowmasters suck on ls1's, but damn, thats too much. ive heard them renamed here on ls1tech to chokemaster, guess it holds water.

Great numbers on the mustang dyno. Intake and cutout should yield some impressive gains on already good numbers.

And holy crap to the posts about the Flowmasters vs cutous.

I had Slowmaster on my 99 Camaro, and I was kind of torn with it. It sounded great, but the power loss wasn't worth it. I'm sold on GMMG catback and SLP Loudmouth 1 (both with a catted y).

420 thru an ls1 intake on mustang dyno is strong, like others have said, let it breathe better and those numbers will only go up!!!

I also have an ms4 camshaft with stock heads lts ory through a chokemaster catback but have a cutout right before the rearend and when i open that thing up it makes a hell of a difference. But with the ms4 and chokemaster catback it makes for a good street sleeper to get some races up and then open it up and they want to back out of the race!!! hahaha
