Get a Euro spec PE as it comes with flapper and trust me it's great, much better than US version.

When I do the golf tee mod on the Euro PE to emulate US spec PE it doesn't sound as nice.

Warning: my flapper started rattling so I had it removed. I would never intentionally get an exhaust with that ever again.

Has nothing to do with warm up whatsoever. It's for sound only. The car is very loud during warm up because of cam overlap (no need for secondary air) and because of wastegate position.

Unplug the connector behind ur left taillight and enjoy. Or get a JB4 and activate the canflap feature.

So if everyone here is sure that it won't affect warm-up I'd b okay with this too. What about misfiring as another member mentioned. Not sure but I saw a thread linking the golf-T mod to misfire codes and such.

If its a go ahead...how do I do this in an 08 335i E93 lol.

Forgot to mention: without getting codes!

Will a muffler delete throw a code, thats what im thinking about doing. Either that or cut outs after the downpipes. That could also be an option for you

My search for a shop to remove the secondary cats at a reasonable price is very frustrating. Most shops around here won't do it and the one who will wants $200! I don't want to go to a shady business. I want the work done right. Stupid laws!

FYI, it will trigger codes. No SES light, but the dealer can detect it. (if unplugged from inside trunk)
