Looking at charge pipes and saw these two options. Why does one have 2 pipes and the other 3? Supposedly they are both for an M2? Thanks

I may have figured it out. It appears that the 2 piece one is just the turbo to intercooler section and the 3 piece one has the intercooler to intake pipe also. Does that seem correct?

One is from the turbo to the intercooler, the remaining two are from the intercooler to the throttle body.

FTP has the extra lower Pipe for the Intercooler to throttle body side.

VRSF option you reuse the lower section and just replace the top.


FTP is a complete replacement of all charge piping, VRSF is not

And I’m sure VRSF would tell you it’s not needed as the factory lower pipe is fine, until they start making it, then it’s “replace the commonly failing part”

Here are some good photos of the N55 with the Intercooler and it’s charge pipes

Both VRSF and FTP replace the pop on the left

On the right you can see BMW split it in half

Both replace the top section of this

Where as only FTP replace the bottom pipe on the right side

I think that if it's going to be all apart anyways that it would be wise to replace all of them. I also found out that VSRF does actually sell the other pipe but for some reason doesn't package them as a set. You have to buy it separately. There's about a 20 dollar difference between the 2 brands.

This isn't correct I'm afraid. I have the FTP and installed it myself, so I know first hand what it has in the kit.

The FTP has both the Boost and the Charge Pipes. The 'Boost' pipe is the part that goes from the turbo to the FMIC, and the 'Charge' pipe is the part that goes from the FMIC to the throttle body (on the right in the picture above).

The stock Boost pipe is made of reinforced rubber and is very unlikely to fail, but I changed it anyway because I had everything off. The stock Charge pipe is semi rigid plastic, and prone to cracking, particularly under pressure.

The FTP pipes are good, but I wouldn't go with FTP just because it has the Boost pipe as well. I'm not sure the Boost pipe is needed.
