Saw a picture of this OEM header setup (see attached) by TTS on Facebook. E-mailed them and got this response from Richard:
"Basically the std headers have an inner heat shield as well as the chrome covers. SO by removing that inner shield and just using heat wrap we can create enough room to up the bore sizes by ¼ inch which obviously releases back pressure. By removing the metal gasket where the headers join the exhausts we can keep the pipe diameter up by the ¼ inch as well. We have also put a Lambda boss in each header so fine tuning can be done. Additionally the blanking plug has a 6mm thread in it to mount the chrome covers too. We made it primarily for complementing our supercharger conversions and it has really made a big improvement, improvements to NA should be there but we have not tested. I am just about to get a batch of 10 made and the price will be £530.00 +vat. if applicable. I utilize the stainless flanges off the original headers so its an exchange service unless I can pick up some headers off ebay. I could supply systems without the flange if you wanted to get yours welded on locally."
On the Facebook page, they say it gave an additional 30 HP on the supercharged engine. I wonder what kind of increase on the NA engine??
After checking into all the available headers for the Rocket, I find they all have drawbacks: CES/Rebands- made of mild steel, Carp Sidewinder- too large in diameter and no baffle. Plus none have a complete heat shield. So here I am, kicking around the idea of this setup tied into a Brocks Street Meg muffler. I know a true header will make more power, but this setup should give good HP numbers, provide a tighter fitting exhaust, complete heat shields, all stainless, and for under $1300 plus shipping and labor to mate to the Brocks muffler! Perhaps someone with exhaust knowledge can chime in with opinions on this endeavor.
