Ok, I have a 2001 A6 2.7t with a catback exhaust. I want to put dmh performance electric cutouts before my secondary cats right after the flex pipes. What size are the stock exhaust pipes? I think 2.25" but im not sure. What size cutouts would I have to buy from dmh if they dont sell 2.25"? I will also have to get rid of the cell that is thrown but how would I do this?
Any input is greatly appreciated thanks.




Here is the link for the exhaust cutouts

ooooh! i love these cut-outs! my friend has them on his b5 s4 w/ 3 inch dp's and it sounds insane. are you gonna be running these after your gutted or upgraded dp's?

I'm going to put them after my stock down pipes and I believe that pipe is 2.25" correct me if I'm wrong and dmh doesn't have that size on their website so what should I do?

 

email them. i think you would be ok with the 2.5in, but not sure. probably gonna pick up a set next month when i get new dp's.

 

Ok I'll email them see what they say

 

I will also get a cell when I have the valves open right? what do I have to do with the 02 sensors? Move them? put de-foulers in?
