MX-5 OC Forum

 Has anybody out there got any experience with this system?

Is it stupid loud etc

Does it give any worthwhile gain in bhp?

Car being used for sprints & hillclimbs, want more go whilst steering clear of forced induction!

I have a full s/s system on my mk2.5 and it sounds ace, but doubt its liberated more than 1 or 2 bhp.

 Not fussed about the MOT side, i can always swop the cat back on!

Seems really hard to find a proper performance "full" system for the 2.5.

Did you have any fitting issues?

 The only system i know that gives decent gains is the racing beats one.

I will be buying one later this year.

 Yeh, I looked at that myself.

I have a feeling that you have to change the manifold as well?

They look a fortune

Doing a bit of sprinting and hillclimbing in the car so need more power without resorting to forced induction (as it effect the class im entered in)

Cheers 

 Yep since the Cat is part of the manifold on a mrk2.5. 

So yes you have to delete the cat at the same time.

You could look at the 949 racing one but if you don't like the price of the racing beats one then you going to have a shock. :)

NA on mx5 seems to be bloody costly

Remember most tracks have dB limits that are quite low and geting low so do check that you will be able to race.

 You're not wrong!

Although i was at Harewood Hillclimb yesterday and nobody even checked us!!!!!!!!!!

If the cat is part of the manifold on 2.5 how can Mongoose sell a decat?????

Confused  

 its proberly listed Wrong and should be for just the mrk 2's
