Would like opinions
Getting ready to install LG headers, have borla stingers on now. What would the differences be with and without the high flow cats? Car will have a tune. Car is a c6 manual.
Thanks

Performance wise, you would gain very little (certainly wouldn't "feel it") to nothing by removing the high flow cats.
Sound wise, it may be a bit louder ... again, not significantly.
If you already have the high flow cats I would just leave em.
I actually got pulled over for loud exhaust (headers and bullets), and the cop looked for the cats. And wrote me up for stupid ticket for illegal exhaust ... he was sure I had no mufflers (the bullets look like the old fashion cherry bombs ... just fatter piping .... I couldnt convince him they were mufflers)
If he had seen no cats I would have problems for sure.
