More Mods or have I reached my limit

[gtp3.8]

Hi guys I have a 1997 Grand Prix GTP. I have already done some work to it I am just wondering if there is anything else that I can do to it with out really tearing into the motor. I already have a ZZP downpipe with a highflow cat, a reprogramed pcm from 3800Perfromance, MSP Cold Air Intake, TB Spacer, and I'm running a 3.4 SC Pully. Is there any other things that I can do with out getting into Things like Cams, Heads ect. Like a bigger TB? I have also looked into getting A set of strut tower braces but thats another post. Any advice or options would be appreciated.

You can put on a set of headers or ported exhaust manifolds to go with the ZZP downpipe. Another thing you can do are larger injectors and new rocker arms with a different ratio to improve flow. This way you won't have to change cams, at least at this point. A larger throttle body is also a viable option for better air flow in and the headers or PEM's will help get the gasses out of the engine.

headers, rockers, and a cat back exhaust to finish it off depends how nuts u wanna go i want to put rockers an intercooler and a 3.0 pully on mine i have all the exhaust from the engine back done and the mods that u i also have already I hav to warn u tho the cat back is super loud on these cars i got the optional resonator and it was loud i had to put one more muffler in and its still no church mouse but its tolerable and the headers and cat back made a huge gain the car really throws u in the seat but it feels slow again mod time there so addictive!
