Ok I have always owned camaros and know nothing about mustangs. My brother needed money so i got his 97 m5 cheap. Ok this car is very slow compared to what im used to with my old z28. Where do i start it has short throw, 4.10, cai, ford puck clutch, and he has 2 cats left with straight pipe and a h pipe, no mufflers and it does not sound all that good and pops alot i need advice on that and any free mods to start with. What are good mods that make a difference any weight reduction. I was thinking headers and x pipe with bullet mufflers and getting mil elims. I want it to be loud and have that awesome mustang sound of course. Any advice will be appreciated fellows!!

i would start out by swapping to a PI top end.

PI = 99-04

What is it that changes when upgrading from the 1996-1998 NPI heads and intake to the 1999-2004 Mustang GT’s is the NPI heads that came stock on all 96-98 GT’s use a different internal design therefore creating the need for a new intake manifold. When you are upgrading your intake and your heads you’ll also need to pick up some additional parts (see below):

Parts:PI intake, NPI gaskets (2), thermostat o-ring, water pump o-ring, updated coolant/heater tube, updated alternator bracket, updated thermostat housing bolts (2), and the updated water pump nipple that connects to the heater tube.

How much hp/tq would you like to be at? This way we will know what direction to point ya in.

FYI the PI heads are not the 4V heads, those are a whole other story with a deep wallet.

Save the money on the MIL's and go straight to a tuner, IMO the factory tune is very conservative and needs free'd up a bit.

Personally, if I were to own a 96-98 GT, I'd go the extra mile and get either ported heads or trickflow heads with a bit more aggressive set of cams. If you're ripping it apart anyway, I think the extra money will be well worth it when you see the jump in power.

I would like to be around 350 to the wheels on hp and tq, any idea what it sits at now?
