R exhaust

[MO1182]

Hey guys and gals,

I just picked up an R last week and love it. One thing I’m kind of surprised on is the volume level on the exhaust even with the valves open. I think it sounds great but was expecting a little bit louder. I’ve read aftermarket like Borla and Corsa don’t affect the volume at all more the tone. Just seeing if any R owners has any input on an aftermarket exhaust? I’ve also seen a few just swap our high flow cats but looks very pricey.

thanks

New HFC systems are limited production now due to EPA actions. Only one company I am aware of that makes them currently is Fabspeed that can fit OEM system. ($2900 or $3800). If you want to go long tubes then Kooks and Stainless Works make them for their complete systems with LT. Maybe Corsa too. Or search and hope someone puts up for sale a catless pipe system for OEM connections. You may have to tune with any of these systems. Not everyone is clear of CEL’s popping up at any point.
Good luck but the R at 4500 RPMs plus should be good enough.

The Borla ATAK system is a bit louder. I’m super happy with mine. Nothing is gonna be cosmic louder; you’ll only get soo far with stock cats in place. Just how it is.

LOL. ride behind it with valves open. It's not quiet.

May want to reconsider if you plan to track it anywhere with sound limits. These things are pretty loud right out of the box

try driving with the rear seats down (assuming you don't have the factory delete) ;)

Please PM me. I have a set of B Line Motorsports "free flowing" mid pipes that connect to the OEM or aftermarket exhaust and headers. I can provide details and pics.

This! My R was so freaking loud that I added small resonators!

Do what you want, just be aware you’re drawing unwanted attention to yourself not to mention the already mentioned track sound restrictions.
Some have experienced being kicked off track with stock exhaust.
My stock non R is plenty loud and I’m half deaf according to my wife

My wife thinks I’m totally deaf.

... and I’m half deaf ...

What??!?

Surprised you think it’s too quiet; I suppose you mean inside the cabin? It’s plenty loud, as others have mentioned you’ll exceed track limits. However, if it were me I’d look into 3” piping; don’t know if there’s any off the shelf kits, otherwise have one custom fabbed along with high flow cats.

Are you in NY or CA? I ask this because in NY, they’ve made it illegal, or at least enforcing with a higher fine, changing your exhaust to be louder than stock. The shop that did the work, if you don’t install yourself, can be fined as well. I know in CA they are major ball busters.

I put the Ford Performance exhaust on my R and love it. I wanted a bit louder in “normal” and it is - probably somewhere between normal and sport with the stock R exhaust. The “loud” mode on the Borla is definitely louder and maintains the stock characteristics. I have always mostly driven in normal mode with both exhausts and save sport for being more aggressive.

Forgot to add that though the red line is 8250 power seemed done by about 7200 which was a bummer to me and the Borla changed that allowing the motor to feel like it's still building power to 8250 That exhaust and a QA1 driveshaft and the motor just snaps to 8250 - as I feel it should.
