Non- Mtechnic rear diffuser insert

[Pursuit]

After searching, I'm still confused.

I have a non-Mtechnic rear bumper and am interested in a rear diffuser insert that will come close to fitting my twin tip SuperSprint exhaust.

I keep seeing references to diffuser inserts, or retrofitting 323 rear diffusers?

Anyone have definite links / pics / experience?

Thanks ~

The insert is only for the M tech rear bumper. The non M tech bumpers don't have an insert. You'll have to modify the bumper if you want to fit dual tips.

Here is the M tech bumper, insert is part #3

Here is the non M bumper, there is no insert.

Gotcha, that explains my confusion. I was thinking there was a part called 'insert for non-M bumper' or something like that. Thanks for the clarification.
