Power Pulse Connecting Pipe for 90-97 Miata


A Power Pulse Miata Connecting Pipe is required with the Racing Beat single or dual outlet Power Pulse muffler assemblies on all 1990-1997 Miatas for proper fitment. The Racing Beat Power Pulse Connecting Pipe is constructed using stainless steel tubing and features our exclusive cast stainless-steel flanges for positive gas sealing. This connecting pipe incorporates a pre-silencer that has been tuned to provide our Power Pulse Miata Mufflers with an aggressive, deep exhaust note.

Racing Beat NA Power Pulse Mid-Pipe 1
Racing Beat NA Power Pulse Mid-Pipe 2 Specifications:

- 2.375" OD Tubing
- 304 Stainless Steel Materials
- Includes catalytic converter/header-to-connecting pipe replacement gasket.
(Muffler gasket is supplied separately with the Racing Beat muffler unit.)
- Includes connecting pipe-to-muffler mounting hardware.

Note
: This Racing Beat Miata Connecting Pipe section does NOT eliminate the stock catalytic converter unit. All Racing Beat Miata Connecting Pipe sections for the 1990-97 Miata bolt directly to output of the stock (or comparable) catalytic converter.

If you prefer a slightly louder exhaust note for your Miata, you may want to consider the use of the Racing Beat Sport Connecting Pipe. The Sport Connecting Pipe does not include a presilencer.


Test Parameter
Racing Beat used their 1990 RB Miata (1.6 liter) in this test. The car is equipped with a High Flow Intake, Racing Beat 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) Sport Pipe (without presilencer)
Idle: 74db
3000 RPM: 82 db
5000 RPM: 87 db
Idle: 75db
3000 RPM: 89 db
5000 RPM: 92 db
(Legal limit for California is 95 db.)

Evaluation
Racing Beat was quite surprised with the sound output of this Sport Pipe! Quite frankly they 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 is louder, Track Dog Racing agrees that the sound is "streetable" and still retains 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.
