Test Pipe vs X-Pipe Dyno Comparisons?
I tried searching but couldn't really find anything concrete. Specifically, I'm looking to compare the dyno results for two different setups:
I'd imagine the OEM X-Pipe w/ Test Pipes would result in less power, but how much? I'm trying to see if it's worth the additional power loss. Can anyone post their dyno charts?

Would be cheaper and less labor intensive to just go catless x-pipe. I made the switch and couldn't be happier with Macht schnells.

I don't think it would be cheaper.. Test pipes are ~250 on the used market and install is not bad to DIY or have a shop do it in like an hour. X-pipes cost significantly more, even if they are used.

X-pipe is about 5hp more than test pipes from what I have seen.

It would be great to compile results of various types of xpipes.
My headers with catless xpipe made +15whp / +8wtq over test pipes. http://www.tdott.me/2019/06/project-...mw-e92-m3.html Did anyone notice how Valvetronic's catless x-pipe makes less power over a fully stock xpipe, than test pipes alone make? Spencer's video only shows +12whp & +9wtq over stock, and it's fully catless. Test pipes usually make over 20whp over stock. I don't have any dynos right now but there were many in the past, just have to search for them.
