hey guys, i'm in need of some opinions on what to do next with my exhaust, i am leaning towards the power log from zzp, or headers, but i am not sure if skewing the injectors is a must with the powerlog, my plans are to run the 3.4" pulley but right now i just want to get rid of my 2-4 degrees of knock with my 3.5" pulley. any suggestions, pointers would be appreciated..

If you can do headers, go that route. Plogs are good, but I've heard about a lot of cracking issues. As for skewing the injectors, you will be fine not doing that right away. Then you can try to find a local tuner that can adjust them for you.

There have been cracking issues even with the 304 stainless steel. Will the p-log bolt to the stock crossover?

Yes, the Plog will bolt on the stock cross over.

If you go with headers you can get a set that bolts on to the stock exhaust, like Pacesetters, TOGs will need to have custom exhaust work done at the down pipe/cat, not sure about SLP headers

I thought there were some fitment issues with the pacesetters on the H body'*? right now i have a 3" downpipe and i deleted my resonator. Do u think the p-log will get rid of my KR that i am currently seeing?

It should help. I see a lot of KR problems with 2000+, they seem to run a little lean.

I think it "may" help if the restriction of the front manifold is the reason why you are getting KR.

We should get together to tune your car like you had mentioned last year at NEBF. Most 2000'* tend to run lean on the stock tune, that may be a big part of the KR.

Yes they do run pretty lean, my LTFT are usually around 7, i plan on buying the HP tuners software sometime soon so i can start learning how to tune myself. I was also looking into getting a tranny cooler to keep my tranny temps down a little.. it seems like the 180 t-stat doesn't really help to keep coolant temps down in the hot weather unless u have your fans set to come on at 180 also. i agree bill a tune would prolly be the best help to combat the KR.

7 percent is pretty lean.

Opening up the exhaust with a P log in the front should help in reducing cylinder temps to a point...but most 2000+ guys do much better with a tune than bolt ons for combating KR.

Meanwhile most W body guys find bolt ons are the better combat tactic as their tunes aren't as lean.

It'* pretty cool since I've gotten into the other body styles to see what works for which car and noticing how GM did tune them all very differently.

yea i have a buddy up here who just got a 01 gtp before winter and has started to mod it. right now he has a 3" downpipe jmb fenderwell intake and 3" catback, and a couple other exterior/ interior mods... i think i still have him beat tho even with the KR that i see but i guess we will see at the track... hahaha
