hey man.. ill take your advice on the intake for now, ill wait a while before i go for a really good high quality one, what sort of intakes could you recommend in the future? as i have witnessed to your point exactly as it happened to a friend of mine where he went for a middle range intake and it made his evo even worse.
The cobra exhaust did cross my mind aswell as the tomei racing titanium y-pipe exhaust system i was looking at too. Also i was looking at plenum spacers on torqen website but not sure how i would go about buying one, im not sure which is a good kit for my 350.
Thats seriously impressive if you're car is making 280hp at the flywheel with 144k on the clock, my car feels solid at the moment, im trying to find ways to modify it without going crazy on turbo kits etc and without ruining the value of the car, what i had in mind was like yourself possible plenum, exhaust system, break kits, tyres, intake and maybe an upgraded clutch kit
