Just got a GTP, have a few questions for the experts

With the 3.4 pulley, how much boost will it be making?

With these cars it isn't how much boost you can get, it is how much air you can move and how efficiently you do it.

I run 12-14psi on my 3.2" setup. I've seen modded Stage 3 Intercooled cars only run 7-9psi and beat the crap out of mine.

on the normal 3.4 setup youre probably going to be seeing about 10 pounds of boost. probably more in the 9.5 range.

and since no one answered this yet, the front powerlog is a replacement for the second most restrictive part of the exhaust system: the front manifold.

your car will be way faster with a bigger pulley and no knock. i would suggest doing all of the mods but the pulley and see if you like how it runs. for safety sake i might even just stick to a 3.5 pulley. the car will feel about the same and itll save you from knocking just that much more.

Thanks for answering that, Would you suggest the 2.5 DP or the 3"? I plan to go with the cat-less one. I seen it on ZZP but there are so many to choose form I'm not sure.....I seen a 3" shorty no cat, is that a good choice? Also wanna keep the exhaust quiet im assuming removing one cat shouldnt make it too much louder then stock right? Thanks again for the info.
