Pulley Size?

RE: Pulley Size?
They will probably work ok, but not optimal.The spark is too cold... it could cause misfires, and cause your plugs to wear out too quick. Your gap will widen, and you'll end up seeing more misfires later on.
I made 234whp with no headers, and stock TB... when I added headers, I hit almost 250whp... still on 104 plugs with 10k miles on them. :-)

Which (If either) will give me more power Downpipe with the resonator removed or downpipe keep the resonator and replace the stock mufflers? If its a toss-up I'd rather have the car sounding sweet outside.

RE: Pulley Size?
The resonator is restrictive, as is the u-bend. Get rid of both, keep your stock mufflers.Your stock mufflers are non-restrictive up until you pass 300whp. The sound is not too bad at all. If you must change your mufflers for the sound, it won't affect your performance whatsever, but if you leave the resonator, you can chop the mufflers off, and it still won't help things, because your resonator is choking things up, causing boost stacking, and higher temps in your manifolds... that's a perfect breeding ground for KR..
Hope that helps explain things.

Causing boost stacking,
But perfect for describing it....
And those mod's are great, for a 3.4 pulley. During the tune, I ran a 3.6.
I put the 3.5 on AFTER the tune. so who knows what kinda HP I run now..

RE: Pulley Size?
Probably not much more, unless you re-tuned. With each change in induction, your existing tune will react differently, throw off your fuel trims, causing inefficiency, or possibly even KR if the fueling isn't right. Should have tuned with the pulley that you planned on running. If you were seeing any KR at all with the 3.6, you'll be seeing alot more if you go with a smaller pulley.
Did you do any scans for KR on the road with the 3.6, 3.5or only while on the dyno?

isn't that the code to smoke a joint (420).
Seriously though, that work shouldn't make you throw acode unless your cat has a problem, or your sensor is bad. I'd also recommend going with a 3"hi-flo cat.... find a 3" In/Out for $75.... since you're doing that whole section anyways, going 3" from the DP to past the resonator will help alot with getting the exhaust out.
