I installed this shortly after installing the silenced cat bypass pipe from MX5 parts. There was no problem with the cat bypass on the original exhaust, but when I added this exhaust it became WAY too loud.
At tickover, the exhaust isn't too loud. At 5000 rpm under load, the exhaust sounds great - lovely throaty, slightly raspy sound...
...at between 3000 and 4500 revs under load, there is a nauseating, eardrum-compressing resonant bass boom. Very loud and very intrusive. The sound itself is cool - there's just way too much of it.
I called round various places to see if there was something I can stick in the tailpipe to attenuate the noise, but it seems that nothing is available. I was going to try it with the original cat fitted, but I think I'm going to give up and fit a standard exhaust.
The build quality on this exhaust is excellent. It looks great. It sounds great, but it's way too loud in the lower rev range when the throttle is applied. This resonance may not occur if you have a cat fitted.
Speed of service from MX5 parts was excellent as always.
