Hey hows everyone doing. I just got a 40th anniv. edition gt. It already had a BBK cold air intake, underdrive pulleys, 3" dual exhaust, and 75mm TrickFlow plenum. How much horsepower approx. am I dealing with?

Pics should be up Friday when i get a chane to wash it.

Welcome to the board. 3" exhaust sounds a little big unless you are pushing some big numbers. Cant wait to see the pics!

I was wondering why it was so big. The reason for the new vehichle was because i totaled an 02 F150. It had the 4.6l Manual V8(same as Mustang) and it could only fit a 2 1/2" system, but I measured and its a 3" exhaust.

Are you just measuring the tips or the pipes?
Because my tips are 4". [8D]

After doing a little looking around on the sites' sponsors the exhaust looks exact to the MAC system.

But back to my original question, would anyone beable tomake an estimate as tohow much horsepower would these hop ups put me at?

I say with those mods your pushing ~240rwhp and thats being pretty generous.

I don't know much about mustangs but i thought the 4.6l v8 GT came stock with 260?
