BTB exhaust knocking on rear beam

[Greeny.]

Had my BTB fitted just after I bought my car, admittedly it knocked now and again after the car was lowered 40mm but has got worse recently. Went to a local garage who changed the clamp as my original BTB supplied one wasn't clamping tightly enough and was causing a slight leak, this has fixed some knocking and the leak but it still knocks now and again if I happen to go over a pot hole etc. What would you recommend to fix this for good? My centre mount was replaced around 6 months ago but is sagging very slightly again so no doubt this would help slightly but still this would only bring it up another few mm if that:

If your car is slammed it might knock maybe, other than that i'd go with mounts?

This is proper pikey but seriously it's sorted me right out! I got some puncture repair patches off my mate at his tyre place and glued a load across the area on the rear beam that is knocking. It still might be knocking but I don't notice it anymore! Sorted!

can you not unscrew the c clamp and move it round a bit so the biggest bit of it isnt facing the rear beam?

Mine used a stainless mikalor clamp at this joint, it did not knock i think it was 68mm.

Never had any of mine knock even on 100mm drop

Nope as there isn't any room to do it up if its facing up!

Ye was looking into these.

Any of your BTB's on a Ph2 172? What Cat/de-cat did you use on each of them?
