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.
