I was thinking about putting high flow cats on my 2011 g 37 or getting a clean exhaust that sounds real nice.. borla maybe?

Get Magnaflow catback, its a bit louder than stock with a nice growl the only thing it does not mix with high flow cats- too raspy then.

Forget Borla & Magnaflow

Look into Fast Intentions, Invidia or ARK

If you want to go for subtle change in loudness get Tanabe Axle Back.
You won't regret it.

I am in the same boat as you are....want a nice sounding Exhaust but not too loud. Lot of people on these forums recommended Invidia Gemini.

I am yet to listen to Invidia(in Person)...so please take this with grain of salt.

i havent heard the tanabe in person but i've heard good things about it, i had the megan racing axel back as my first one. It was a also a nice subtle change, currently still sitting in my garage haah

well if you want clean sound then Invidia or Tanabe mufflers are all the way to go..

Others are either loud or raspy

I have the Gemini. I think it is perfect for me. It doesn't have the LOOK AT ME volume, but it has an amazing tone. Def. louder than stock though.

besides stock, Tanabe is the most popular one. There's a review on the Tanabe with vids but I think he has the full CBE and HFC I'm not sure. https://www.myg37.com/forums/intake-...nd-y-pipe.html
