Hi all
Only had my zed 2.8 widebody a couple of weeks now and have found out that the loud exhaust note ( which I love ) from the race exhaust has a race cat that's to small to do the job of getting rid of the gases !!... What's my options guys as with the windows down the small gives me headaches !!

If you are getting an exhaust smell inside the car with the windows down, that sounds more like an exhaust leak.

An engine with blocked Cat's gives poor engine performance and stuffs up the fuel trims as the engine can't get rid of the gases. There is no gas escaping other than the end of the exhaust. This would be similar to an overly restrictive small Cat.

Cheers sounds like I'm looking for an exhaust leak ?!.. I have had the car in for a pre mot but will fail on the emissions due to the small cat
