I'm currently running a Stillen exhaust and decided to get a TS diffuser as a few older post on the forum have confirmed fitment with cutting up the diffuser.

After some cutting in the rear section, and a slight gap between the bumper and diffuser(where the two bolts are mounted to the U bracket), the bottom of the exhaust canister is still SLIGHTLY touching the diffuser in the middle section.

Hoping someone running the stillen exhaust can help/provide pictures to assist me as I'm not sure if it will end up melting the diffuser and/or my bumper.
