So I have finally decided to go with an ARK grip cat back exhaust, BERK high flow cats, and Stillen G3 intakes for my 2010 G37S coupe. I'm going to have them installed by a local shop, but was wondering if it is ok to have all three installed at the same time. I don't know much about modding so I don't know if you should install one at a time so they break in or what-not. Any info you can provide would be nice.

 

All installed at once is the best way to do it bro Less on labor

 

Thanks man. Just got a quote for installation of all three from a local shop and they said $350. Done deal!
