Testing: Invidia N1 Single

Invidia N1

As we are at the final stages of developing our own race inspired exhaust system, we were invited to help Invidia perform testing on various designs of exhaust systems. Videos have been posted on IG & FB #rz1usa

After a fun filled day with the boys at Invidia, it came to decision time.... A clear winner - N1 Single.

We prefer the OE look but sound wise, it was night and day:

Deepest tone & closest to the 'rumble'  - Just had to be the N1.

Invidia is Not our Sponsor nor are we getting paid for promoting this product. It's on our car because it was the best selection and we think you'll appreciate it. At least until we bring out the Street Legal Race Spec CAT Back Exhaust System in a few more weeks!!

Note: Our Race Spec CAT Back Exhaust will be on a brief introductory sale when its ready for release. Images and sound clips will be posted here and on our social media. Stay 'Tuned'
