Recent newbie, recent purchase and close to me! Do tell what you think of it, especially as you think it's better than an RX8.

Thought so as O2 control should be in a closed loop. Thanks again.

Thanks, both. Did you return the tune to stock before the MOT or leave it as-is?

Question: is the second cat alone enough to pass the MOT emissions test? Do they visually inspect for the first cat? On my CRZ, it's the other way round: first cat with O2 sensor left in place, second cat replaced with HKS exhaust system. But being hybrid, there is no emissions test!

Thanks, Kevin. I'll take you up on that closer to the time. Where is the best discussion of unequal length headers, cats and overpipes?
