Stillen Headers + Berk HFCs self-install report

wstar

A couple of updates:

I ran by an exhaust shop Saturday morning. They heated up the hangers for the center section with a torch and bent them a bit to get more clearance at the crossmember. It's no longer laying on it, but it still kinda touches and rattles there a bit, depending on exhaust temps and the phase of the moon. Hopefully I'll get it sorted out permanently soon.

I got the Stillen Gen3 intakes put on today, which completes all the major boltons (Intake, Headers, Cats, Cat-back). The install is really pretty easy, although it takes a little thought and tweaking up where the filters are. Butt dyno is still pretty impressed, the sound coming out of them is nice. I've only driven about 10 miles on them so far though, so the ECU probably hasn't even caught up with the changes yet.

I'm going to go back by that exhaust shop sometime early this week and have them sort out the crossmember issue once and for all somehow (and maybe have them weld the slip-joints so the clamps can be removed), and then schedule a dyno for the setup. I'm really interested in how the dyno looks now. My Butt Dyno impressions so far is that the upper rpm range is better all around, but I may have traded a little low-rpm torque for it (which is kinda expected with such a free-flowing exhaust setup).
