Miata 1990-2005 · Miata Exhaust & Mufflers · Catalytic Converter


Miata catalytic converters often clog with age and choke off performance. If your Miata won't accelerate strongly in the upper RPM range it may be a failing catalytic converter. Note that the 1990 through 1997 Miata came with a bolt in catalytic converter but the later 1999 through 2005 Miata had a converter welded into the exhaust midpipe.

REVIEWS

RE: RoadsterSport Stainless MX5 Miata Midpipe Part# 60-1328: I love the mid-pipe!! Not only is it beautiful, but it makes the sounds coming out of the 'race single' exhaust even better. The two go well together, and it mellows the decel drone a lot. I'm very happy with my purchase.

Purchased the RS Max Power header and midpipe. THESE ARE TRUELY A WORK OF ART! CRAFTMANSHIP IS TOP NOTCH!! SITE PICS DO NOT DUE JUSTICE TO THESE ITEMS! I recommend Brian's site to ANYBODY with a Miata/MX 5. Brian and Co have taken a great automotive platform and elevated it to it's FULL POTENTIAL!
