Install date is still set for March 29th after I get back from Colorado.

Looks like great quality though, I can't wait to bolt them on.

Looks sick. Hopefully these add a healthy 8-10 of RWHP and a more aggressive exhaust note.

those does look really nice... i'm tempted...

looks nice!

I just got mine in also, waiting for my injen exhaust to come in before I install these though.

Usually id vote against this, since you wouldnt be able to really isolate power increases from each mod, but since they are both exhaust mods, might as well do both simultaneously while youre under there :biggthumpup:

here's an independent dyno from a G37 driver.

13whp

I'll do a dyno on April 5th too

I cant believe how flat the power curve is on these VVEL 3.7's , it looks almost fabricated!

I think it's just the VQ engine (he was also on smoothing 5)

here's my stock dyno on smoothing 3

I have the stillen exhaust. Would this be a good mod to accompany it? Also, where did you get it and how much was it?

its a group buy till the end of the month on myg37.com. its around 475 shipped. i put my order in last week.

check it out...

The test pipes are even more tempting.

would you guys say these will give higher power gains (less conservative) than the stillen hfcs?

I would think they'd be pretty close.
