Thank you. You have rated this product.

Miata mufflers come in many flavors and this Racing Beat Miata Muffler includes Dual Tips and all stainless steel construction. This Miata muffler uses an inlet tube that features a thick, cast-stainless steel flange that provides excellent gas sealing capabilities. Additional strengthening for the inlet and outlet tubes on this Miata muffler is provided by supporting gussets and hanger support rods. Stainless steel outlet tubes feed a double-walled tip for an aggressive and sporty Miata muffler look. The two 3.5-inch exhaust tips are manufactured using polished 304-stainless steel and are slightly oval in shape to provide a perfect balance and proportion with the Miata's rear bumper.

Applications: 1999-03 Miata (except manual transmission models).

Muffler Fitment on Auto Transmission Models

Due to ongoing discrepancies with regards to the mounting flange bolt-hole spacing on automatic transmission cars, we are suggesting that you measure the flange bolt-hole spacing prior to placing an order. (Why Mazda decided to use a different flange on the AT version has left us baffled! Sorry for the extra work required to determine the correct exhaust for your application, but we'd rather have you order the correct muffler and avoid the hassles and expense of returning the wrong part.) If you have any questions about these measurements, please give us a call for assistance.

We request that you measure the flange bolt-hole spacing on your car to confirm that you will be obtaining the correct muffler for your application. The measurement of concern is the spacing of the bolt holes on the flange between the muffler and the connecting pipe section.

Note your measurements as follows:

Automatic Transmission - 3.46" (88mm) center-to-center

Manual Transmission - 4.33" (110mm) center-to-center

If your measurements match the specifications for "Auto Transmission", then you have selected the correct product listing. If your measurements match the specifications for "Manual Transmission", then you will order Power Pulse Exhaust for "Manual Transmission."

BRIAN'S APPLICATION NOTES: Our other brands of exhausts, such as RoadsterSport, simply slot the flange holes to avoid this potential issue.

Brian, Thank you!!! We last spoke in November about some upgrades for my 2011 MX5 soft top. It has finally warmed up in NE Ohio and two relaxed weekends of wrenching on my car were well worth the effort. Installation of the RoadsterSport ceramic coated street header was straight forward and took under 8 hours, including a 40 minute test drive and cleanup of the garage! Combined with the RoadsterSport Q exhaust, the sound is fantastic and the increased torque, horsepower and performance make it a blast to drive. The addition of the Cobalt shock tower brace, Racing Beat sway bars, ILM front power train and X braces really enhanced the ride - minimal body roll, comfortable and very responsive. Your recommendations really helped transform the car from great to fantastic. Your research, product development and candid recommendations make you a standout in the industry. My only questions are - what's next on my list .... And how soon will my wife want the same upgrades on her 2012 PRHT ... Again, thank you!!! Charles G
