Default Rim of the World Rally

Ok guys, I actually have two questions regarding this setup, and just so you know, I currently have the GT spec headers....
1. How does a TBE sound with the GT Spec header combination?
2. Will I see a much bigger power increase from a TBE and GT Spec header combo than just the header alone? In other words, once a TBE is put on the car, will the added flow take full advantage of the headers and produce significantly more power than just a TBE alone?
All help is most appreciated, and if anyone has any exhaust clips of the GT spec header with a TBE that would also be nice

Be sure to have some form of boost control or pressure will drop. It will allow for a much much much larger flow overall though.

1. How does a TBE sound with the GT Spec header combination? depends on the exhaust, with my leak finally fixed the GT + godspeed catless + blitz nur spec R is insanely wicked sounding... definitely scares the v8s
2. Will I see a much bigger power increase from a TBE and GT Spec header combo than just the header alone? I sell these headers and XXtuning has dynoed them to do 16whp 18wtq on a STOCK sti (headers only) as you start adding mods, the amount of hp and tq you gain from them increases In other words, once a TBE is put on the car, will the added flow take full advantage of the headers and produce significantly more power than just a TBE alone? They will work hand in hand... the headers will produce more hp when combined with a TBE and vice versa... also I'd recommend an intake... i felt a BIG gain when I put my apexi back on (I have been stock box for a while) (used to have perrin).
All help is most appreciated, and if anyone has any exhaust clips of the GT spec header with a TBE that would also be nice
I WILL FINALLY force myself to go do a dang video of my car tomorrow... i'vebeen so far behind i havent been able to.

I love my setup, GT SPecII header, GS DP, Blitz NUR Spec Touring.

It sounds awesome and pull like a mofo!

I'll have it dyno'd on the 15th of may.

dp + gt spec header = awesome combo. i decided to keep the stock exhaust to prevent any hassle from the authorities. however, i love the way my stock exhaust sounds with dp and header. i used to have the blitz nur r on my car, very, very nice unit. ill prob be selling it when i get back home.....
