Ok so now i have a full stainless steel custom exhaust and a TRD panel filter , powers up a bit , acceleration has noticable improvments....

So whats next ? apart from a swap or turbo/supercharger is there any other worth while perfromance mods ?

i searched but not much info on the 3sfe here

thanks

Chris

What about the ignition system.....

a grounding kit couldn't hurt
