You will get your downshifts and Im unsure about the intense pulley I bought my 3.5 from zzp and also bought the pulley puller which I sold after using it.
I had a scanmaster for a while and only saw KR when it was hot as hell and even then it wasnt much and it was at the 1-2 shift.
Check clubgp sale section for kick ass deals
I couldnt tell a difference at all sound wise to be honest. As far as I know as long as you leave the resonator in place you should be just fine. That d/p will make a big difference since it deletes that u-bend.
I shop at ZZP for the most part but CluGP has a huge for sale section. My d/p is catted and if I had to do it again I would get a 3" not cat d/p.
stock I ran 14.8@93 w/ 2.0 60' so yeah I knocked off a little bit without spending a lot of money. Its a fun car that doesnt get driven much anymore since I got the TA...Not sure on the price of the p-log its been several years now but I had less than 5 hundo in everything including 100 for intense can tune
I bought my GTP with 75k on it and now have 135k. I love this car. The only problem Ive had to date is driver side window switch and regulator replaced. Car has been super reliable. I drove it in Cali for several months in 118 degree temps with no prolems. Bulletproof motor with a S/C. I am running 14.1 with shitty 60' with less than 500 in mods...Ive seen a best of 32 mpg on the highway on long trips with cruise set. Its a bad ass reliable car and the whine is lovely....
I say get it... It looks good and sounds like a damn good deal. Do you know if its ever been modded? HUD is awesome to have as well...
