Hello everyone. I am new to the forums here. I am currently driving a 2010 G37xS sedan. Haven't done any performance mods yet but I am looking to get started. I'm not looking to do anything too drastic, mostly looking to replicate the stock coupe sound on the sedan. It sounds like the best way to do this is to throw in a set of high flow cats. I'm also planning on installing a short ram intake. Today I stopped by a local custom exhaust shop and they told me that they had a set of Magnaflow high flow cats that would fit on my G37. I couldn't find any reviews of any on here. It sounds like Berk and Fast Intentions are the best route to take...they are the most widely used and get the best reviews on here. Has anyone used Magnaflow HFCs? Are they any good? I don't want to risk getting interior drone/poor quality on something that doesn't have very many reviews.

Thanks!

 

I have not seen any magnaflow HFC's for the G's magnaflow are usually universal cats.

The sedan exhaust is different size diam, and the resonators are larger to tone the exhaust down, You can try a set of axle back mufflers if you are just looking for sound. But I would really look at a catback system. BTW the RWD cat backs should fit out X sedans. I have a coupe RWD sysytem on mine before .

Short ram intakes EH:/ will pull hot air, maybe look at takeda's if you havent bought them yet.. OH Welcome!! Lots of good info on here also.
