Invidia Midpipe - leave it in or remove?

[Murfman89]

Hello, 

I now have the Invidia midpipe installed with stock exhaust (IS 250 2012). So far I am not happy with the investment. Very little sound change and comes to find out that I won't pass CA smog when it comes to it. 

Getting a custom Magnaflow Axle back muffler (Saturday) exhaust and wanted to know should I stick with the Invidia midpipe and add the Magnaflow? Or pull the Invidia midpipe down, sell it and install the Lexus midpipe back in, install the Magnaflow and maybe have the resonator replaced with a glasspack or cut out entirely. 

Thoughts?

I plan to keep the Invidia midpipe installed with the Magnaflow custom exhaust and just swap the pipes when it comes to smog check time, which is 1.5 years away. 

Thanks.

By now you have Magnaflow installed?

Yes, the setup was way too loud and the drone was unbearable.   I had the Invidia midpipe removed/sold, OEM pipe reinstalled, now just have the Magnaflow Axle Back installed which sounds nice.   A little drone at 2000-3000 but if you drive in S mode it takes care of most of the issue with drone. 

Honestly, I find if you don't have a stick shift car, you really shouldn't mess with the exhaust very much since the cars shift sooo low now.   My MCS with JCW had the resonator deleted and never had an issue with drone noise, but the cabin was louder and that was stick.

Good info on Magnaflow. I have FSport exhaust with similar results on IS350.
