G35 Power Adders - Before and after dyno test/ tune2win

Hey everyone, thought I'd post this link for anyone whose interested in seeing some before and after dyno runs for some mods. Including uprev tune, JWT intake, sg longtube headers, T1R cat-back exhaust, Motordyne Y Pipe. Theres also another link for installing a quaife lsd differential. I bought this car in March of 2011 I still have everything except the JWT intake. I can say that the exhaust does have a bit of a droning noise at highway speeds but after a week of buying it I didn't notice it at all anymore.

http://tune2win.com/index.php/projec...5_power_adders this is the link for the before and after dyno stuff.

http://tune2win.com/index.php/diy_te..._installation/ and heres the link for the diff install

Yea the headers look insane, they're wrapped so doesnt look as good as they would without the wrap but the wrap is 100% necessary. Only a few people have these headers, and since SG Motorsport went out of business noone will be able to get them made anymore. Kinda cool to have something thats one of a kind, i Just hope i never have to take them out to replace any gaskets because its such a tight fit.

and to shane11 i believe you should get the xyz pipe and a tune if your looking for the hp gain but if the xyz pipe is 3"you gotta figure what diamater pipe its going into. Also i forgot to mention that the flex joints are already starting to fall apart and they're only 2 years old without being winter driven.
