I’m wondering what the stockThe OEM downpipe has a 53mm or 2.09" outlet.
The TSP downpipe opens up the coffee straw restrictor with a 72mm or 2.83" outlet (35% increase).
In the near future, the TSP downpipe will be mated with a Fujitsubo front pipe and exhaust (70mm or 2.76") where they should marry up very well. On the intake side, the OEM turbo compressor outlet is 50mm where I added HKS intercooler piping of 54mm going through a J's Racing intercooler.
exhaust ID is after the front pipe. If that flange ID on the front pipe is smaller than the piping after, it would seem to be a significant restriction after replacing the downpipe. I would be up for upgrading the front pipe, but I’m not really wanting a louder exhaust, nor do I want to spend the money.

With the out end of the OEM downpipe being 53mm, the in end of the OEM front pipe is the same. I would imagine the out end of the front pipe to be the same size providing for a full 2" exhaust carried through to the back where the pipe splits.

I am glad I found this. Great thread. I’ve been going back and forth with these same questions for weeks now. I am about to install my TSP downpipe with TSP blanket and that Dream cover is exactly what else I had in mind but didn’t know existed.

I initially thought about that. After installing the PTP hybrid downpipe blanket and DA heat shield, I was very impressed with the results. So much so that additional shielding on the hard water pipes was not worth considering.
Here is a link to my CTR build thread.

Bump for me to check the ID of the out end on the OEM front pipe.
