the 540 has some new goodies and a new sound>>
got the intake & hi flow cats sent over by Revhigh, eliminated the resonator (thanks sean & united) and w/ a remus exhuast it just sounds nice and feels very strong now.
This was from start up, then slight idle, then slowly up to 2k rpm and then a few bigger revs.
I love the new sound - it is only loud during heavy acceleration, at idle its just about as quiet as it was, but under heavy acceleration it sounds pretty mean!
Almost sounds like a blend of my 650rhwp Z & a v8 stang (not that i dig stangs) - but doesnt sound "ricey/lawnmower" at all.

thanks again Rev,

PS - much much much more power now w/ the Revhigh ECU upgrade, CAI, resonator elimination, and hi flow cat swap.

Saw her over at united muffler when I went to take my friend to pick up his supra from there. What were you having done there?

was having the hiflow cats put on and the resonator eliminated. I've know sean (united muffler) for about 4 years now and i used to have him do work on the Z when i first started and he's a nice guy - but there's only certain things i'll let him do and thats mainly exhuast stuff.

They need a mandrel bender before there was much that I'd let them do. They made a pipe for john and its hideous IMO. He doesnt mind it, but jesus I thought it was ugly. The guy is very nice I agree.

Example - my check engine light came on today and i believe its cuz his welds may have a leak in them which triggers my check engine light for the hi flow cats.
yes - they need a mandrel bender!!
