RKTek Secondary and SLP Exhaust on 07 M8

[Headrush]

Hello,

I have an 07 M8 with a RK Tek torsinal secondary, with what appears to be a 34 degree helix. I am going to run a complete SLP exhaust on it and am wondering if that angle helix is going to be any good for this set up? It also looks like there is a green spring in there as well.

Thanks!

You are probably close with the 34, (at least around here at 9000') if you don't mind a straight cut helix. A better choice might be a 40/34. I would run what you have and see how far off it is. I'm running a straight 36 RKT w/ and SLP single.

Thanks, I am actually thinking of just running a RKT head instead...

I had the RKT 34 degree helix on my 07 m8 that with the RKT head really made a difference it was a super fun sled till i got an 09 m8 and now its the funnest sled. But you cant go wrong with RKT products.
