Awesome, thank you for picking up one of our engines and pipes, please let me know what your thoughts are once you get it broken in and have some time on it. If you have any qeustions please do not hesitate to contact me or you can also contact Thommi who is out importer for Brazil and is also fluent in Spanish if that is easier for you.

In regards to the conical manifold though while we may not currently offer it please keep in mind that this is just the start for us of getting back into the on-road racing end of things, where we actually started. So we will be continuing to develop on-road oriented engines and products for the GT market and if it's found or felt that a conical manifold is needed, it will be made.

I'm just not the type of person that makes a product just for the sake of having something to sell though. So if we make it, it's going to be tested and will have to be something that I would run my self. That's a basic question I always ask before releasing each of our products. "Is this something that as a regular racer I would spend my own money on and be happy with"? If the answer is no, then the project gets trashed and we do not sell it.

Back in the early 2000's when we did sell conical off-road manifolds we offered 3x different lengths and in testing we found that as you mentioned there was a noticable increase in bottom end, however we also found that the engines (from that time) then topped out so quickly in rpm that real conical manifolds were pretty much only suitable for use on small to medium sized tracks. My saying this though may have something to do with the difference in actual manifold designs because back in the days I found that a lot of manifolds that are referred to as conical (meaning the tubing that the manifold is made of expands in diameter from the start of the manifold (at the engines exhaust port) to the end where it connects to the pipe) were actually not really very conical lol! So it was really more of a marketing term used by most companies. Most of the exhaust stuff back then was (and is still) being made by hand in really small factories in Italy and it was quite time consuming and expensive for us to have actual conical manifolds made. Again though that was with 1/8th buggies with older engine technology and probably most importantly only single speed transmissions not two speeds like in todays GT cars. So again please let me know what you find in testing as I'm always open to input from others on ways that we can improve our product offerings!
