Mazda Miata Racing Beat Sport Connecting Pipe for years 1990-1995 Miatas

The Sport Connecting pipe was originally designed to accompany our older style, “reverse-flow” Sport Mufflers. We have since discontinued the line of Sport Mufflers, but many customers have requested the connecting pipe that was sold with these systems. For those of you that would like a “louder” and lighter exhaust system, the Sport Connecting Pipe can be used with our Power Pulse Muffler. Unlike the connecting pipe that that is intended to accompany the Power Pulse Muffler, the Sport Connecting Pipe is NOT equipped with a presilencer. Produced from 2.375" OD 304-stainless steel tubing and flanges, this connecting pipe will offer years of performance driving.

Many people ask just how much louder the Sport Pipe is as compared to the Power Pulse Pipe. For comparison purposes, we undertook a series of decibel readings to record the sound level outputs.

Test Parameter
We used our 1990 RB Miata (1.6 ltr) in this test. The car is equipped with a RB High Flow Intake, 4:1 Header, and Power Pulse muffler. The different connecting pipes were installed and the car was lowered to the ground prior to testing. Using a handheld decibel meter, a sound level measurement was taken at a 45 degree angle, approximately 18” away from the muffler tip, The measurements are as follows:

Power Pulse Pipe (with presilencer)
Idle: 74db
3000 RPM: 82 db
5000 RPM: 87 db

Sport Pipe (without presilencer)
Idle: 75db
3000 RPM: 89 db
5000 RPM: 92 db

(Legal limit for California is 95 db.)

Next, the Racing Beat sales staff drove the car to obtain subjective opinions on the sound quality of the Sport Pipe configured exhaust.

Evaluation:
We were quite surprised with the sound output of this Sport Pipe! Quite frankly we were expecting to hear a harsh, buzzy tone without a presilencer, but this was not the case. Although the sound seemed to increase sharply at 3000 RPM, it was NOT harsh or buzzy but retained the deep, throaty tone that was similar to the resonated connecting pipe. Even though it was louder, we all agreed that the sound was “streetable” and still retained the sound quality of the Power Pulse system.

Conclusion:
A lighter weight alternative to the resonated connecting pipe, the Sport Pipe offers a modest sound level increase over the Power Pulse Pipe, but in our opinion this pipe is adequate for street or track use.
