Hi folks,

In a Wrx if I was the swap out the up pipe for a straight pipe to get rid of the pesky cat and then change the back box to a cobra or similar one leaving the centre cat in place, how much difference in noise do you think this would create?

Nice burble or too loud?

 

I have a cobra exhaust from the downpipe back, still have 2 cats in ill get a video today for you if you like

 

Awesome yeah that would be great if its not to much hassle!
