I have a stock 07 GT with the stock TR-3650 manual and stock clutch. My powertrain warranty is up this year and I thought about some simple bolt-on mods. I have the SCT Pro Racer Package with value files for a variety of air intakes, and wanted some recommendations for a setup that will give me a verified 315-325+ hp at the crank, and is OEM-quality (something Ford would use at the factory) with no maintenance issues (and readily available air filter elements).

I did the exhaust (axle-back mufflers) awhile ago but I couldn't stand the noise. After riding my Ducati (wearing earplugs all the time due to the sound levels of the bike), I guess I could go back to my Pypes Violators wearing earplugs - but I don't know the verified (if any) power gains from those axle backs. I'd rather be quiet and fast.

very simple install.
Or bring your car to Mustang Alley at the Woodward Dream Cruise and have it installed there.

Or buy this version

and best bet is to see Lidio at Alternative Auto in Chesterfield Twp for a dyno tune with awesome drive-ability.

 

I see you have a tune already. Get a cold air intake. I'd recommend the C&L cai (because I have it) or really, just about any other cai that requires a tune. Underdrive Pulleys are a nice 10 hp gain as well.

 

Go to American Muscle and purchase one their SCT Tuners along with a CAI. That should easily get you 25 to 30 HP at the crank with a BAMA tune.

Steeda pullies should add about another 10 as another poster stated above.

If you want a relatively quiet exhaust.....just keep it stock....but if you have the regular plain tips.....maybe consider getting the mufflers with the nicer rounded tips that you see on the California Specials.
