Midas to install a catted downpipe?

GA/\/\/\/\A_CT · 02-17-2021, 01:45 PM

Would you guys trust a franchise exhaust shop like a Midas or Meineke to install a catted downpipe on a BMW 340xi? I have a BM3 stage 1 tune if it matters...

How hard is the install? Is it better to have a BMW expert do it?

It's a handful of bolts. Unbolt them, remove old cat, place new cat, put bolts back in. Cant really mess it up. Takes less than an hour with a floor jack and hand tools.

Any shop can do it.

Most cats don't come with a gasket. I would recommend ordering one and replacing it to be safe.

I used a local exhaust shop. That's all they do. I'm sure you have a typical exhaust pro shop nearby.

Thanks guys! And to be sure, an X-drive doesn’t complicate the install?

No,same part,straightforward install.
Get a new clamp in case it's needed.

Joke to install on a x-drive as well. Having a lift is nice, but I did mine with jackstands on the garage floor.

NFW...last time I stopped at a midas for an emergency flat repair. They sent me off with 65psi in it. Just pay a shop that deals with BMWs or DIY. It's not hard although my have to cut vband clamp bolt on some.
