Doubtful. Going off of memory as I don’t have the engineering images to reference remotely but I am nearly certain the reason we went the whole length is the vast majority of the stock mid is hydrformed pipe (ie: not round) which is required to get it to mate and create a seal without gaps. Pretty sure the first round section where cutting could occur was within a foot of the cats anyway so rather than make another cut for little reason (no real cost savings) we extended it all the way so it could just be unbolted and dropped on that end.
I didn’t realize it before, but do you know if the mid pipe will be compatible with most secondary cat deletes? I have the evolution race works one, and it looks like it has a bigger diameter than the stock cat. From what I see, the midpipe slides over the cat. Wondering if it’ll work with a non stock cat.

Evolution Racewerks fits the factory midpipe so if the Dinan mid is designed to fit factory downpipes, it should be fine. I have the Evolution Racewerks secondary cat delete on mine. Factory mid and back though.

Ordering now! I already have secondary catless so can’t wait to hear the difference!

Please post a before and after sound clip with the x-pipe. I've been on the fence as I don't want it to be obnoxious.

Welp, I think I just made the same mistake. Both look like they are designed to fit over factory piping. So if both increase in diameter at the mating point. We may have a problem. Guess I’ll find out when I go to install both.

EDIT:

Nvm… I lied… should be fine based on these pics I snagged from another post by QdaNoob's user avatarQdaNoob (tagged for photo Cred)

What are reasonable shop quotes to get this and secondary downpipes installed? Im getting quotes in the $800 of both jobs. Doesn't it seem like on the higher end? They have to remove the exhaust to access the downpipes cant imagine the mid/xpipe taking too much longer.

I saw this post and I think it should be fine. Will report back here today if there’s an issue with it.

I think I paid $400 for secondaries. This was in 2021.

I was quoted $100 for the midpipe now.

Got it installed. Worked with evolution race works secondaries.

The sound increase is pretty good, I’d say if the secondaries was 10%, this is adding another 30-40%. The burbles are a lot more pronounced and idle sounds mean. The tone didn’t change much from stock, which is a good thing because I like the stock tone.

There’s no drone, another plus. Overall I’m satisfied with it and don’t think it needs any further changing.

sweet, would you mind creating a vid of the sound with open and close valves? I have secondary cat delete and planning on this res delete.

Great news!!!

Video would be awesome! Can help me and others determine the difference with my 3 piece system I just ordered ( ER secondary, x pipe & axle back)

Dinan X pipe

Took a quick video as I got to work, will try to take a better one later.

Did open/close valves in comfort and open/close valves in sport (second half)

Man that sound is fantastic! Plus the turbo spool is awesome! What RPM were you hitting? Sounds like maybe just under 3K? Also, do you have an intake on that beast? Wondering if I need to give Dinan more money for that spool! Lol

Kept it under 3K RPM.
No intake, only second cats removed and now the X pipe installed. I didn’t notice the spool until I recorded that video, usually blasting music 😂

This sounds perfect!! Can’t wait to get mine all installed. Should be by this weekend! 🙏🏼

I’m planning on getting the Dinan x pipe and axle back so basically a full cat back. What should installation cost and anyone in Buffalo area know reliable installers to make sure the valves don’t get messed up lol. Thanks

That sounds so good. I have ER secondary catless and buying this x pipe as well. Can’t wait to install. I also have to install some drop in air filters to help a bit.

What's the story with the warranty? Does this void it or is it like everything else where it depends?

Stock cats are retained so there should be no issues with factory warranty. The only thing that would not be covered by BMW are exhaust related which after install would be Dinan components and not their issue anyway. If something were to happen in that regard (unless improperly installed) the Dinan warranty would apply which matches the factory new car warranty (first 4yr/50k).
