J Pipe Recommendations

Is there really any benefits of upgrading the J pipe if the oe pipe still works fine?

Nope. A metal j pipe will just increase IATs based on my data logging.

Best combo is silicone charge pipes with the stock J pipe.

Good to know. My thoughts too... just flashed the stage 2 flex map and plan to change my mishimoto charge cooler to the wagner per Ian @ bend so I thought about doing that as well for a second

Interesting, please share the data

It’s made by the shop I linked in the Instagram post, most likely custom.

Why are you looking to change your Mishi TMIC to Wagner?

Wagner provides a reduction in Temps. Mishi performs worse than oem.

please share the data regarding Mishimoto performing worse than stock

It was in bends white paper

I find it doubtful that air moving at that rate of speed is being heated to any measurable degree through such a short and large diameter pipe.

I wouldnt compare mishimoto to VRSF. The mishimoto is a better quality and performing intercooler compared to VRSF and CSF.

It outperformed the stock system. https://www.mishimoto.com/engineerin...oler-2015-2020

Mishimoto's test was done with their upgraded front mount heat exchanger.

Ideally, they should have only done the test with the top mount intercooler in place and kept the heat exchanger stock to compare the stock intercooler performance vs. their own.

I have not compared the cooling of all three, but judging from the build quality, CSF has the best finish, followed by Mishimoto, and VRSF is last.

I assumed they probably saw little to no change in temps when doing intercooler swap only.

From what i read, their testing showed that the stock heat exchanger wasnt efficient. They installed their heat exchanger and measured b4 and after. They then installed the mishi intercooler and got a very slight drop of 3F degrees compared to the stock intercooler(negligible). So very very little difference on the 430WHP tune... Too bad they didnt have a more powerful car to test with.

"With just our heat exchanger installed, we were able to lower the global system coolant temperatures by 10°F and an additional 3°F once our intercooler was in the mix."

Also, i checked out Bend and Wagners site and their data is for a pure stage 2 775WHP car. The mishi site shows it was stage 1 tune with around 430WHP.

I bet if you used the Wagner IC on the stock tune, it would be little to no change in temp compared to the stock intercooler because the stock parts were made to handle the stock tunes heat capacity.

So yea... If you are making 700+ WHP, go with wagner because they designed it to handle 775WHP heat capacity. If you are stock, you might be wasting your money. Thats how i read all this "data".

For me, i didnt want to deal with a potential of coolant leaking into the air intake so i went all metal. Im stage 1 but i wouldve stayed stock if that leak issue never existed.

Sorry to go off topic. I dont plan on changing the J pipe but if i did i would go titanium even though air travels too fast to soak any heat. Does anyone make a titanium J pipe?

I changed the J pipe to ER and it added a bit to my IATs. I'd keep the stock J pipe.

As far as titanium, I do not believe anyone makes one out of Ti. Maybe Rk Ti would consider it if there was enough interest.

A couple of notes:

The Wagner is 33% more efficient so power can be freed just from that alone (iat cooling aside).

The Wagner’s power gain to be had is amplified at higher power levels.

Even if a J-pipe is Ti, it may not flow as well as the OEM piece if it’s just 3in. I went down this route a year or two ago and I was going to custom 3d print a j-pipe for myself from inconel or Ti, modeled after the cast aluminum do88 j-pipe with some sort of heat rejection applied on the outside (fins/lattice/gold-tape/etc.)

Do88 j-pipe is on the car now. The flow seemed more important than the material… do88 being cast had the best flow as the oem piece is 3+ inches in diameter

Apex Built is the only company I know of that’s makes a titanium j-pipe.

Increased IATs aside, a non plastic J-Pipe such as ER for longevity is preferable no?

It would be if it was a common failure point (but it isn’t).
