We are the only maker of complete cat-back systems for Fiat 124. Dyno data on the site with ton of details, more videos, pics, numerous configuration options, etc.. www.good-win-racing.com/Mazda-Performance-Part/61-2104.html
I actually loved the full roadster sport exhaust with the resonator and muffler delete, until I installed the high flow cat. Now it's too loud, what can I do?
Note this is the SystemOne video, not RoadsterSport. As noted in the video, we found we wanted BOTH a helmholtz resonator and a rockwool resonator in the setup after we changed to the highflow cat. Assuming you actually have RoadsterSport brand, put the stock cat back in, or have a muffler shop weld in a much BIGGER magnaflow resonator in the midpipe.
Just ordered this exhaust! Thanks for all your hard work.
Driving you 2012 CN Street PRHT Build, and still, love it!!!
I wish I could drive with my top down in Houston
What are the hp / torq gains, and is the switch back all the way down to muffler California legal?

A right hand drive car or is the video just flipped?
Not sure why the video flipped, but indeed it did and we have 'normal' left had drive 124.
