These things look awesome! Check out some of the dyno gains with these downpipes. They would be the ultimate setup with some Sport 700's and MS manifolds. http://www.twinturbo.net/net/viewmsg.aspx?forum=general&msg_id=2033426
Cant really justify the price for them just yet, i mean if its around $800USD just for something 0.5" larger, not worth it, lets see what S2S can do price wise to get me "interested" as PZP's bargain is the go for me atm
They look ok and the longer split section is definately the way to go. I wonder what ground clearance will be like though in 3"? Best dumps ever i think are the custom ones on shifters car, i think there are some pics on this site somewhere i will put a link up if i can find the thread.
Pics and info OK these are the ones I'm talking about. Shifters are a one off custom but looking at copying them for my car. Once the jig is made up it would be easy to mass produce these at a much lower price.
The pics are hosted on the UAS website so if it's still down the pics won't work. They should come good once the website is fixed up.
Can't say that I like the design of those dumps on shifters car purely for the short length of the divorced wastegate pipe to me would cause more turbulence than some of the others out there but that is just my view. To date I still say the CES racing dumps have the best design with divorced wastegate entering at a point to really take adavantage of free unhindered flow to increase velocity rather than be subjected to turbulence. The worst problem with them is ground clearance, they suck big time which is amplified on the drivers side. I have always loved the SZ divorced dumps for their overall design for flow and position design. 3" will be a hinderance for the lowered Zed but the SZ dumps design with the lower flange positioned higher to take advantage of having the pipe closer to the floor rather than a dam flange to hinder is a big plus.
No divorced section on shifters setup... Other than that i agree entirely longer divorced section is better, apparently a minimum 30cm in order to make an actual difference which means all those tuneagent style dumps are next to useless... The thing i like about these ones and also on fate's dumps is they sit nice and high. Shifters in particular had to as they were made to replace CES pipes when he was defected for ground clearance.
The ces d/p's like very similar to the d/p's sold @uas, which I think originated down south. I had a quote from ces to match pe1420 turbo?s and it was over $1000. The d/p's power enterprise recommended were not devoiced, same as shifters. Clams off up to a 50kw increase in power by some makers should be taken with a grain off salt. A near stock zed (stock toubo's)will not get that kw increase. The boys with forged engines and bigger turbos will defiantly see improvement, but they already know that.
