Anyone used them? the reviews from thier site look promising.
And I cant find to mutch info on those parts.


looking for comparison's on turbos like the Big 16G Evo 16, new FP18g anf 20g.

As you guys read, its a true 3" with 2" waste gate passage. and considering I have the new FP18G. im worring about the 2.5" exhaust housing, stepping out to the 3" and having turblance problems... should i be concerned about that?

Since that downpipe is an o2 eliminator it will be harder to take off than a normal dp. That alone would prevent me from buying it. Besides that it looks like a nice piece, although expensive.

Aye it is expensive, but will reduce a few compressor problems, due too to small of a O2 housing, and DP up till the Flex.

Probem is I keep thinking of those ultra cheap stainles tubular O2 housings, and a megan DP with the 2.5 to flex.... But in the end all that does is save me 45-60$.

considering my FP 18Gsl is been flowed at almost 44-52 pounds per minute ( more than likely with a SMIM and cams, But) has a preported exhaust flange at a perfect 2.5 VS Big 16 at 44 with a exhaust side that needs to be gasket matced to a true 2.5... Im just worried about turbulance, from going 2.5 to 3".. I do know ther are TONS of ppl running the 2.5 to 3" but how does that perform as a DD?. Or is it sutch a small Performance loss that its not worth it up until around 450- 500+ HP...
I will be 2k jet coat the O2 and DP. then Wrap it up. so In theary the 3" with sme treatment should hve similar high flow characteristics...???

If you guys have better suggestions, PLS advise. I'm open to all.

Im open to all suggections..

VRS makes a true 3 inch O2 housing/DP (not O2 eliminator) for a better price. They're on sale right now at Slowboy, 330 for 3 inch stainless steel.

In terms of flow and transition, I really like the FPM J-series DP.

That intake mani looks nice. But for the price you could get yourself a jm smim for 60 bucks cheaper. But it does kind of give the sleeper look a bit and you keep your mid range torque. Depending on the setup could be a good alternative for a smim.

I remember when my brother used to build these for forcepower... Its an awsome downpipe.

The flanges were all laser cut, stainless flex section, tig welded in our garage . I run one on my e316g set up and it sounds and flows awsome. as for price, he never even made any money on them... it was him working in the garage every night after work for like $20 profit on one haha. he quit making them but I believe forcepower now has the design for them and will build them upon request.

someone mencioned about them being hard to remove... it is quite a bit harder to remove one from the turbo but well worth it. (a hacked allan key will do haha) also I used a pipe expander on mine to give it the same I.D. as the rest of my exhaust was O.D. so now all i do is slip on and off my exhaust when i feel necesary.

I have an old school RnR O2 eliminator and I love it but it is a pain to get on and off when your car is on jacks in a garage. It's a lot easier when it's on a lift.
