That won’t help I think. The crossmember of the subframe below the cat stops it coming downwards.remove the swaybar completely which will let you remove the muffler + cat,
It is good but it’s strangely hard to tell how good.How do you like the result of the cat removal ?
Like you, I installed the valve controller first and running with the valve open all the time obviously makes the car louder.
Then running with the cat bypass makes it a bit louder but it’s hard to put a number on it without a back-to-back comparison.
I had the valve controller on the car for a few weeks before doing the cat so I’d kinda forgotten how it sounded when completely standard.
If only doing one mod then the controller is the way to go, especially as fitting the bypass pipe is much more work.
