I am curious who sells tII dp flanges? I am gonna get a shop to custom build me a 3" dp that tapers down to the stock cat and have an electronic 3" exhaust cutout on the dp to run open dp when I want a little more kick.

 

Any competent machinist should be able to take your stock one and copy it over to a new flange.

 

Alright cool I think Im gonna take it to a local custom exhaust shop and have them do it up.
