Question: I have a stock exhaust, want to buy the M Perf Exhaust at low price online and have it installed. I don't know the install process, but I would hire a indy shop to do it for me. But how easy is it to revert to stock exhaust at lease turn in? does this install do any permanent cutting to the existing parts of the car? I just don't want to be charged for any mod's/damage to the car at lease turn-in

You cut the existing exhaust and install the new exhaust with the supplied clamp. You can uninstall easily to go back to stock

The pipe clamp supplied with the performance kit can be removed with the M Performance muffler when you go back to stock. You can buy a $18 pipe clamp from Auto Zone or similar when you put the original muffler back on. This is my plan next year when I trade my M235i back in.

That's great to hear, I might do that.

Do you know how much time and money it would cost for a indy bmw shop to have it installed? I'm planning to get the part at low price online and have indy shop install it.

do it yourself! super easy

A small tip: whoever does the job, get some anti-sieze compound for the install especially the bolt/nuts used. Makes it a lot easier if you have to remove it in 2-3 years for lease issues.

You'll be anxious to get the switch-job done smoothly and quickly at that point with no damage or cutting again. Anti-sieze makes a nice difference.

as long as its back to stock not hanging off you will be fine at lease end....its not something that is checked so just make sure you can install it all back to stock!

Enjoy!!!! Buy AWE!!!!!

I just did!!!!!

M Performance exhaust is too much imho!

Just do it yourself. 30 minute job, 45 if you have to run to autozone to borrow a pipe cutter.

Here's the DIY I followed except I didn't do the exhaust flap golf tee mode.

Note to the above....
The M235 does not have a dimple mark on the exhaust pipe like the 3 series did, you will have hold up the new exhaust and mark the cut point.
If you do the exhaust flap mod on the M235 all you have to do is unplug the flap prior to cold start up

Same is true about the exhaust flap mode on the 3 series also, however, it has been reported that it does throw some codes. Nothing on the dash but the dealer can see the hidden codes. Not that the dealer or anyone would really care. Maybe it's a gateway mod? Next you're buying jb4's and looking for meth...

Possibly, but on my 235 no codes are present. I did the mod on my stock exhaust then put it back and now did the mod again with the MPE & Stage 1 and the P3Cars gauge that reads and clears codes have not shown any. Not say'n the dealers can't tell but they are not hard codes
