Thanks.

Sorry for the lack of updates everyone, the long tube headers are on the car and I have had the car tuned by uprev. Some quick mini reviews:

Long tube headers:
These definitely open the exhaust up, where as before with just the berk exhaust it sounded like a deeper slightly louder stock exhaust. This setup completely roars now, under 3k it is a bit quite which can be nice when driving around town or just going to the office, but as you get above 3k it opens up quickly. Wide open throttle is a blast, most of the time. The one downside to the LTH with Berk exhaust is I have some rasp now. Now is this the berk exhaust of the LTH? Not 100% sure either way, but over the past few weeks with them on the car I have come to "enjoy" the sound more, even with the bit of rasp.

Uprev:
Now I got the car tuned right after the headers were on the car so no true way to do a "butt dyno" on how the tune really helped. I believe they told me I gained around 5-8HP from the tune and around 10 pounds of torque across the entire power band. Overall the tune has left me very happy because the car feels more responsive down low and seems to not be as laggy when starting from 0.

For those wanting exact numbers: 289whp & 225lbs of torque
I will try to scan in the dyno sheet tonight or tomorrow, also this was on a Mustang dyno in around low 90s temperatures (early Texas summer weather).
