They are in Denver North Carolina. They do work for NASCAR and were really cheap surprisingly, but that was in 2006. Did my fd downpipe for $60 $20 for shipping. I would have to say it would be more now.
You can put your hand on the pipe after engine is warmed up. I didn't think that was possible but...

It made 227hp, not bad with power steering, a/c, and a restrictive RB catback and the stock fan. Just an electric fan would have allowed 230hp+. Logan has proved that.
Logan wanted to do the full exhaust but being an old guy, I like a more quiet exhaust note so I can listen to my classic rock cds while I drive around my old Rx-7. lol

That is awesome!
I'm sure everybody including myself would love more photos of the header! Or the whole exhaust system. Any idea on the primary length before the collector?

Actually the hp is pretty impressive considering how quiet it is.

We are definitely happy to make 227 with such a quiet exhaust. The header was built using my formulas, but the racing beat exhaust threw it off some. Now that it had been to the dyno, I think adding 2 inches will add possibly 10 hp. We were running break in plugs too, which new ones add 2 hp or so. I think the car has 235-238 in it. Rick is a great customer, very easy to work with. I won't be disclosing the length, but pics of the whole system are on our Facebook page

Got the GTUs back yesterday. Haven't had time to really drive it. Drove it in the wet today. couldn't really do much. The engine sounds great. 226 hp Logan has the dyno info and he will post it.
There's more power there. I just like how quiet it is and how the engine sounds. It's a beautiful thing. I may have said that more than once now.

I can't wait to see some footage! I've been wanting to hear a 13B on the defined headers, but no one seems to have any videos of it.... Quick off topic question for you Logan, are your 6-port headers made for stock ports or for more of a street/bridge port set up?
