Monza Cat Back Exhaust System Mazda MX5 Miata 1990-1993

I finally purchased and installed the Pacesetter Monza Performance exhaust on my MIata and I have to say that I was very pleasantly surprised at the purchase and the value. The body of the catback is a sleek black with very nicely welded seams and the metal looks like it will last for longer than a couple of years (though not as long as a Stainless Steel muffler would).

It goes together relatively well and is quite easy to put on the car. The only problem I had was with the U clamp that came with the catback was too small and I needed a new one.

As for the sound, I like thr growl. The old (OEM) muffler was already loud from rust, but this muffler has a low throat on low revs and screams on high revs. I was suprised at the increased throatiness of the engine on addition of the catback and performance was definitely increased, more so than any other performance enhancement on my car. I would definitely suggest this catback.

As for the price, the quality of the product and the final outcome, I would have to say that this is a good purchase for about $170 and a weekend in the garage.

    You spent a whole weekend installing a cat system? Well anyways, I was thinking about getting the Flowmaster American Thunder Series, then I saw the Pacesetter exhaust cat back system. I do say the price is very very reasonable for a cat system, but was unsure of the quality and precision of the make and type. and you pretty much answered my question so looks like I would place my oder very soon. It’s going on a 2000 ford Focus and just with a muffler tip after cutting the muffler and that resinator off, it’s very loud with a slight increase since I through away that muffler and restrictor LOL

    Do you still have your 1990 Miata? I am the 2nd owner of a 90 Miata and I am looking to do some upgrades on it. I was wondering if you are still pleased with your exhaust choice.

    Robert, yes I still own the Miata and an very happy with my purchase. It still sounds good and no rust. The fit was not perfect (there is some rattling and the exhaust tip hits the bumper a little) but otherwise it is a good buy.
