Does it work with the vert braces or did you have to remove them?

I found this when i was looking on fastlanes web site

Granatelli Motorsports #500063
Fits 2010-2012 Camaros
Direct OEM replacement, won't void your factory warranty
Adds significant horsepower while improving mileage and throttle response
Straight thru design insures maximum flow but still no obnoxious sound or drone
T-304 stainless steel
Polished 4” tips with rolled edges
100% complete, bolts-on in about 1-hour with no welding
I would also install a set of long tubes if you want to get a decent gain out of it
hope it helps
