Default 3 inch exhaust options

Trying not to trigger the salty replies is hard on this one... so be nice I'm seriously having a hard time trying to find what I'm looking for.

I'm looking for an all 3" exhaust from the cat back to a street muffler for the NA chassis. I May, or may not run a cat. Trying to avoid the high flow straight type mufflers seems to leave me with little options. Any good suggestions? I have some options out for a custom setup, but I've been struggling to find what my options are for a prefabbed done deal. Note that it has to be all 3 inch.

Sorry for the nooby questions! But what would be the smart option for the downpipe if I'm trying to go for a complete exhaust. The 2 bolt flange kinda like stock, or 3 inch v band?

Thnx

Is this going on a turbo car? "3 inch exhaust" and "trying to avoid high flow straight type mufflers" seems contradictory to me. Either you want flow or you don't want flow. On a n/a or mild FI car there are plenty of smaller off the shelf exhausts that are going to flow plenty for sub 200whp. If you're turbo and want flow, straight through is the way to go. If volume is the concern I've got a 36" long 3" resonator to a big magnaflow straight through muffler that everyone runs and the car is super quiet.

I see.. Thanks for clearing things up. I am trying not to sound stupid loud, so the resonator is probably a good thing.
Planning on going the efr 6258 route, so you're right, I do need a high flow muffler.

I'm looking for a muffler to fit in the stock position like the oval type magnaflow ones. I don't mind it being a little louder. But it would be sick if I could get a resonator same size as the stock cat, just to swap in the cat for MOT. As far as I can find, it looks to me like most 3 inch resonators are a lot longer than my 475mm cat.

I'm thinking Kraken has me covered for the whole deal but let me know if you have any more suggestions!

Best to get a full 3" if you already have the turbo manifold and 3" downpipe sorted from said vendor. If not, some places like ARTech might ask to send your setup so they can make you a full custom 3" exhaust.

I run the big *** magnaflow muffler and nothing else, efr6258 to kraken 3" Downpipe to custom fabbed 3" exhaust all the way to the big magnaflow.
its quiet. Not stock quiet, has some nice and throaty sound when you get on the happy pedal, but cruising around it's almost stock quiet.

if you dont mind not having shiny stainless work of art piping, any shop can make you a 3" exhaust. Just provide the pipes, bends, muffler and resonator if you want.

my downpipe had a stock 2 bolt flange, so I can put my stock header back in if I need to remove the turbo, which I've done.

You've done what? Haha

Anyway, thanks for all your help! I went with Kraken to do the whole deal. I had not bought mani and dp yet, so this is probably the easiest.
