Bought these to replace my stock mufflers to go with my test pipes, with that combination, sounds amazing. Very burly and aggressive towards higher rpm. Look awesome too. Took 30 min to install. One bolt each and remove from hangers.

Have had these installed for ~8 months now and these sound awesome on my 07 G35 sedan. A low, burly sound at lower RPMs. Install was only challenging due to my exhaust pipes already being rusted. Shipping was quick and packaged very well
