im just spit balling ideas but if you still got the cats and need extra bread you can scrap em man they bring good money too like 100-200 a pop. Wish you luck on it. Do ya research about these transmissions. Car sounds great even on 4 cyl but you gone get her back to 8 and have it sounding mean. Fix that power steering pump its doing ALOT more then youd think...tuff pov
See if that Zzp equalizer will work in the 5.3 gxp that’s used for the 3800… probably make that thing sound like a Maserati and get rid of that rasp… it makes those 3800 sound like the OG 2nd gen Supra with 2JZ… lol
