Miata exhaust...kooks or RB
In the market for a new exhaust. For my 02. Currently have a RB header I am going to install but trying to figrue out an exhaust.
Is a kooks exhaust with the RB header going to be annoying loud? Its a track only car and the kooks is 375 vs going RB mid pipe/exhaust which isnt in stock and i would have to wait and also 200ish more expensive. Not sure if I want to be cheap or not but also dont want to hate driving the car even for 20-30 minute session.
Anyone have experience with the kooks and a RB header?

Kooks is the "quieter" Spec Miata exhaust...which means that it's still ear splittingly loud. And a terrible tone to boot.
I have the full Racing Beat exhaust from header all the way back to race muffler. I personally think it's a good volume and outstanding tone. Saving money on exhaust only ends one way: with it sounding like crap. If you care about that sort of thing, then any of the Spec Miata exhausts are not the answer.

The Kooks is basically a knock-off of the MBS Spec-Miata exhaust that has been around for quite a while (https://mandrelbendingsolutions.com/...ainless-steel/). I've gone through a couple of these and have the following observations:
Pros:
1. Lightweight.
2. Cheap.
3. Bolts directly to the header, no "test pipe" required.
4. They sound pretty good and are relatively quiet FOR A SPEC MIATA EXHAUST.
5. Lowest possible restriction (given the 2.25" pipe limitation).
Cons:
1. They don't last very long. I've blown out the muffler on 2 of these. They tend to last 1-2 seasons.
2. They create a higher-pitched exhaust note than more expensive exhausts with larger volume mufflers/resonators and there is a definite resonance around 2.5-3K RPM (which doesn't matter on track).
3. 2.25" is your only option per the rules.
I gave up on them and am currently running an Enthuza on the track car -- a much more durable option. I would never run one of these on a street car.
