    ISR exhaust system really made a huge difference!
  

*by J***. on Reviewed in the United States on April 9, 2022*

Going from a stock exhaust to the ISR Exhaust System really made a huge difference in sound! Paired with long tube headers you’re able to shoot little flames while driving hard.

    BUYER BEWARE
  

*by R***. on Reviewed in the United States on January 17, 2023*

This exhaust sounds so good, but! If you have strict parents this one aint for you it is quite loud over 3k rpms and it does sound pretty good. It was very easy to install on my 1.6 miata other then the fact that the cat would not fit correctly and I had to use different bolts to get it to work. If you have a lift it'll be 10x easier. Exhaust note is pretty deep and has a little bit of rasp at higher rpms.

    Sizing Isssues
  

*by C***Y on Reviewed in the United States on February 6, 2022*

1991 Miata, overall good how ever the sizing is a little iffy, it doesn’t line up great with the headers so there is a small leak, can be fixed with after market headers, also one of the hangers on the muffler doesn’t line up. However the other three fit well. Overall sound is good.
