Would love to have my ride next to a long tube stainless power headers setup to see if there's a really going to be a $2k + tune difference in sound.
The volume goes up a lot with long tubes. Even with high flow cats, it doesn't hush the volume near as much as the OE primaries. From a performance gain perspective, it's hard to justify the price tag on exhaust shit these days. I did the entire exhaust on my '08 Mustang from headers to tips for less than half of what some of these brands want for just their mufflers for these newer vehicles. Say what you want about R&D. I went with the Extreme Online Store's LT's for this build. Quality is "okay" but one header flange needed a machinist's touch to put it right. Guy felt bad even charging me for such a simple tweak, but I dropped $100 for the job and $50 for the tip. Otherwise very happy with them, they fit perfectly, look good, and do the job. I could lie and say I had Kooks and no one would know the difference looking at them. If the heads ever to come off again, I may look at coating & painting.

First, how the hell are you passing CA emissions with secondary cats removed?? The entire reason these cars have secondary cats is CA emissions standards, they catch the shit that gets through the primary cats during initial startup while the primaries are still warming up.

Second, I'm surprised CHP & local PD doesn't pull you over constantly. Have seen numerous shorts of them harassing Camaro's, Mustangs, & Hellcats for running open valves or being in track mode. Even if you stay in touring, the valves will still open up at throttle. That's OE factory, not the driver.
