How much louder is the tomei catback and test pipe compared to just the tomei catback with stock cat? Is there any drone? How is it in the cabin in lower RPMs and high RPMs while driving on the freeway?

 

From what I can remember, the switch from factory cat to the test pipe wasnt that much louder, if anything at all. With the Tomei cat back, it's gonna drone no matter what (unless of course you use the silencer, but who wants to do that, right?) Lower RPMs sound awesome and aren't annoying at all (sometimes I drive with the radio off just to listen to it haha) As for high RPMs on the highway (cruising at about 3500-4000 RPMs in my 6 speed) there is quite a bit of drone, but nothing too crazy. You can still have a normal conversation with someone in your passenger seat. Overall, I absolutely love my Tomei exhaust and wouldn't trade it for anything else!

 

Everything drones IMO. But from my experience and hearing different setups in the shop, the Tomei one was one of the quietest. PM me if you are interested cuz i'm running a special on Tomei parts.
