I'm currently running a '99 mk2 engine in my mk1 with an ME221. The car drives great but I'd love it to sound a bit better, I'm running a racing beat exhaust manifold matched to a silenced decat, but still have a standard cat-back exhaust for the rest of the system.
I did briefly try a Cobalt exhaust but the drone was awful once the car got up to temperature so it came off and was sold. I have been running a K&N typhoon for the intake but due to heat-soak issues I've reverted back to a standard airbox.
The MX5parts exhausts seem to have a bad reputation for noise, plus the fact that I had to return two of their manifolds in the past has put me off buying an MX5parts exhaust. So here's the question, are there any cat-back exhausts that are not stupidly loud or drone excessively but just give a nicer sound?

AK Automotive systems sound lovely. I agree!  I think they might only be for the 1.6, and then only with a de-cat arrangment, though?? Could be worth giving them a ring to check! |

I 'fixed' the cobalt on my car went from horrible loud to being able to hear the induction by 'fixed' I removed the stupid tailpipe & replaced it with plain pipe (hacksaw & tig to the rescue  ) as to other exhaust recomendations, sorry but I'm of no help there Rich. ps. anyone want a cobalt stainless tailpipe? |

Any pics? Having trouble visualising this or understanding how it might make a difference. Cobalts do mellow out considerable with some use. After a couple of months the worst drone was gone. Then its ok for a year or two as the packing slowly burns away. Then its back to droning. |

After reading lot's of positive reviews on here & Pistonheads I've booked in next week at Infinity Exhausts for a cat-back to be fitted next week, quite looking forward to someone else working on the car rather than me!

I have heard good things about Infinity exhausts, anyone have experience of them? I've used them a few times - I currently have a cat back straight through pipe and small silencer from them, very good work, you can watch them do it. Basically they'll make you whatever you want. |

It would be good to hear how that goes.
Regarding the AK system. I remember seeing a Nutz thread a while back about the system that mentioned dyno testing during the development. Are there any graphs or anything knocking around on the web that show this? I have looked but couldn't find any.

Not that loud really. I think it was around 90db at 5fest last year. I have a Racing Beat manifold, and still have the cat. The cowl intake makes as much noise inside the car.......Disclaimer: I'm deaf in one ear, and wear earplugs when driving the 5  |
