Exhaust setup help
they will all match up, the 2 1/4 inch cat pipes into 2 1/2 inch y pipe pipes isn't going to make a huge difference.
none of it'll make a difference unless you get a retune ...
with that being said everything will work if it was designed for this car. Keeping the cats will help tone-down the rasp but anything without a bonafide muffler is going to be raspy...
go on youtube for sound clips before you pull the trigger on anything -

Edit: if I used test pipes instead of cats and just swapped them back when inspection time came around would I need a retune every time?

i was looking into getting a uprev tune as I have read some good reviews I just don’t want to go down the route of using test pipes than switching back to cats for inspection and than retuning to put back on test pipes

You will be fine. There are ppl right now with full Boltons as we speak and have no tune. You are just swapping the cats for inspection. Drive normally with the stock cats and swap back to test pipes.

my only concern is if I do get test pipes and get a uprev tune and switch back to cats for the inspection than throw the tests back on after would it have to be returned because of the swap
Bolt n go.
You can tune if you want like an extra 10hp... But most of that is with the tune aka adding timing, not the exhaust. Exhaust is mostly for sound. The 2-3 HP you gain should be an after thought.
But no you do not need a tune.

I would like to thank everyone for sharing information with me, I’m starting to understand everything now but I have one remaining question that’s been sorta answered. The tune as you said adds timing etc and just clears the code for the test pipes. If I have the tune on and take my test pipes off than put on cats than put the test pipes back on afterwards will that tune be unaffected (as if nothing ever was changed, check engine light will not come back on after the test pipes were reintroduced)? Hopefully that makes senseEdit: another way of the question that might make it more easy to understand is say I have a tune than I purchase a new part will that new part be at it’s full potential because of the pre existing tune or if adding a new part would it have to be retuned.

the tune does not change, swapping test pipes with other test pipes in theory shouldnt change anything.... now say you add headers, plenum spacer, etc... you would need to retune to get the benefit of those
