Cheers everyone for the advice, much appreciated!

Cheers for your help, I’ll have a look into the manifolds. This might be a stupid question but if I decided to get a cat back at a later date, would it need another retune? Or does it not make that much difference

Thank you for both your replies. Would you recommend getting anything else done in addition to the manifold and filter before a remap?

Apologies if there’s already a thread about this but I’m new to the forum! I got a GT86 (14 reg) about a year ago and have finally decided I want to do a couple of mods to it. The first thing I’m going to do is put a K&N filter in as it’s an easy one. One thing I want to do is get rid of that brake squeak at slow speeds. Is this just a case of getting different pads? If so what pads would you recommend? Also, would there be any power improvement from just replacing the secondary cat with a high flow sports cat? I want to improve power/reduce the torque dip but want to keep both catalytic converters so it’ll pass an emissions test. Are there any other mods people recommend to get me started? Thanks in advance for your help and sorry for the long post!
