Default 14' exhaust on NNBS

Has any tried a stock or aftermarket 14 and up catback on a NNBS.

It's time for a change in the exhaust dept on mine and Borla has a dual side exit exhaust for the 14 and up 6.2's that drops twin tail pipes right underneath the quarter panel behind the rear wheel. It's really hard to tell but the hangars look like they are in the same position and I know the frame is identical to the NNBS trucks and the Ypipe is unchanged also.

Looking at the Borla install PDF, it looks the same to me.

Check out the magnaflow exhaust. They have a bunch of options and I can get you good deals on it if you find a system you like. PM me if you find one and I will get you a quote.

What I would like to see is the Borla Atak system on a GMT900. The Corsa Sport seems pretty close in sound comparison.

It's more like a resonator.
