Sorry about that my mech says there are different part numbers for the different sizes you may need. I will pm you his number he said to give him call when you get the sizes you need and he will get them for you.

 

super interested in buying a set how soon until they go in to production????

 

Ds.... any progress on fixing the tb problem and redynoing the headers? I wanna see the "real" after dyno and track times...

 

no not yet I'm getting retuned next friday at RT tuning with a new TB with the track on saturday. I just switched the location of the xpipe and resonators around on my invidia to get the merge closer to the headers.

I'm going to replace the invidia x with a magnaflow due to the rasp after switching locations.

The gemini has the resonators on the y pipe instead of the x pipe like other exhausts. The x pipe is after the resonators which puts the merge further back.

I'll make a before and after video.

 

Sweet, can't wait to hear it

 

sound like you are making good progress over there! im planning on using the tdx2 with the ppe's... any thoughts on that exhaust at all after your experience with your current one?

 

one thing just hit me... for the revup cars, are there gonna be provisions for both the factory narrowband AND wideband sensors?

 

The revup replaces the narrowband secondary o2 sensors with wideband ones. So you still have a total of 2 primary and 2 secondary.

 

I've read the merge has to be close to the engine. The Gemini has their x after the resonators.

The TDX is good since Tony (MD) made sure it was in the optimum location for power as is merge on the XYZ pipe.

Read his XYZ pilot production thread he explains the importance of the merge location.

I just modified my Gemini to make it similar with the merge location. The Gemini is the only exhaust with the x in a different location.

Every other exhaust (Ark, stillen, bassani, FI and MD) has the x pipe in almost the same location on or right after the Y bend I figure there is a reason for that.

 

Here's the thread if anyone needs it. I made the merge on my exhaust at the exact same place as the XYZ. Turned out well.

Thanks Jairen for the link.

 

gabe, thanks for your reply. i havent gotten under there to look at how its all installed yet, but im assuming what you are saying is that these headers will work for revup, and non-revup... correct?

 

Should work with the rev-up O2 sensors. I'll post a pic of the clearance around the steering rod tomorrow. There is plenty of room left.

 

Dsskyline, did you guys have to make an extension for the primaries? Just noticed that all your bungs are at the merge.

 

I've ordered my pre-production set, should arrive before x-mas.

From the pics on page 1, it looks like PPE supplies an O2 extension kit for the primaries, kudos to them for that.
