Hey!
My friend just got a 1991 NA and was looking at some stuff to do to it. As far as exhausts go, does anyone have any experience with Mazdatrix's "True Dual" exhaust (it's the 1st one on their exhaust page w/ the video)? It seems quite expensive @$1200, but if it does give the 28% increase in rwhp...

Anyone...?

Thanks!,
Manolis

 

mazda trix knows whats going on, i bet its worth every penny, they have been around a long time and have the most parts ive ever seen.Id say if you have $$$ go for it

 

I have true 2" duel.....cant say i noticed that much of a difference. Just my .02. CJ

 

I agree with CJ. It made a difference, but not nearly 28%.

The true dual is very loud. If you like loud, no problem. If you dont, you want a single exhaust.
