Yeah, it doesn't seem like a workable solution at all.

 

I'm not sure it would affect flow that much. Especially if your going from catted DP's to catless, there will already be worlds more air-flow through them. I'm going to attempt the install later this year I will keep you guys posted.

 

Have you seen the Dr. Euro downpipes for the 535i?


Notice that big chunk taken out of the bottom pipe?

 

so has anybody actually tried this? I cant find anyone that has documented the install.

 

I plan to sometime this winter, need to save up some money first. I'll post a day then if no one beats me to it.

 

I know this thread is old but has anyone tried these on a 535xi?

 

I think he posts on this forum also.
