To keep the stock ISF mufflers or aftermarket
I have a custom 2.5 x pipe straight pipe from stock headers to stock mufflers. No secondary cats and no resonator. My question is, should i change the stock mufflers? I like the sound of my custom exhaust set up to stock mufflers as it is quiet but i hate the fact that my inlet to the stock mufflers are smaller then my pipes. I feel there is restriction by the stock mufflers and I'm not getting much hp gain for it. I've seen the pics inside the stock muffler and it really looks restrictive. What can i do to get full exhuast utilization and no drone noise?

Going to be hard to get no drone, best route I can think of is the Borla axleback.. I would avoid custom exhausts, personal opinion, unless you get the work done for dirt cheap
