Corsa x-pipe installed

Longtubes are definitely worth it in terms of performance gains and sound, and helps to set you up for other mods down the road. I do need to make a bit of a correction here though, and that is that you do not have to get Corsa headers to go with your x-pipe. I've never actually even heard of Corsa headers, as far as I know they make pipes and mufflers, but not headers. I could be wrong, but regardless - Pipes are pipes and although you may need to extend or expand some pipes to get things to fit, you can choose any brand of headers that you wish. I use American Racing Headers, but Kooks are also highly recommended for their performance and more importantly, their fitment. If you have to hammer a dent into a header to get it to fit, you are kinda defeating the purpose.

I would also like to add that H-pipes and X-pipes are usually used in forced induction or nitrous cars where the back-pressure can cause unwanted restrictions, and is typically added after you have done other modifications first. I guess my point here is that adding one in will not do anything to change your volume unless you are removing the catalytic converters and replacing that section with an X-pipe.

Sorry for the long story in my previous post, that was unnecessary.

Love the accountant in the passenger seat comment. It only becomes a problem when the accountant does an audit. Hide the books.

I have a 2015 Z51 with ARH mids, high flow cats, Borla catless x-pipe, B & B Bullets, no NPP (deleted and removed) and a Halltech carbon CAI. The AFM valves have been removed and the function deleted via a tune. The car is loud all the time, but reasonable, unless it's at wot. I think the headers will give you the sound you're looking for. If not, the mufflers are next. Enjoy.

I’m thinking of picking up the arh mids with high flow cats. I have yet to decide if I want a tune on my 19 gs or wait. I was told that the newer arh mids with cats don’t require a tune. I know you mentioned you did a tune on yours. How much gains did you end up with?

Sorry OP if you feel like I’m hijacking the thread I can start a new one
