Yep it was about 800 for me after they were installed and exact same issue, maybe they make our 40th's extra difficult lol. I'm glad you like it man the art pipes just make it so much deeper and louder, is it a lot louder for you? Still no drone? That's a nice setup man. I basically want/ have the same thing, only difference is I'm thinking about doing the AAM midpipe or going crazy and getting the Motordyne shockwave omg have you heard it?

I got the ART pipes installed, 850$ later lol... Shop needed to cut of of my bolts off and it was a pain in the ***. But its ******* amazing... it's a race car now lol. Next **** I want to do... Stillin Gen 3, Oil Cooler, and ARK Grip catback, then tune =D
