Why is it a waste of cash?? Im using a decat and std exhaust on my 172. It sounds a bit raspy but nothing to loud and the main difference is at max chat. When i put the cat back on for the MOT the car felt restricted as if it was being strangled, took the cat off after and its alot better. Its a worthwhile mod.
