Depends if you are external or internal – either way, bigger does no harm at all.
Couldn’t agree more.
I’ve seen cars make 350rwkw with a 3” as well. Swap it over to a 3.5” and boom, another 15-20rwkw and better midrange. Some are users here (some have also posted, which is good)
Just because it makes the power, you can get a 3” to 400rwkw no problems, doesn’t mean that putting something bigger will not provide benefit.
Well with 2x 3.5” straight through mufflers (they are massive), I’m around what, 90dB, so it must be possible
Mufflers weren’t cheap, but they certainly have some effect.
Not really no, 3” with little bends and straight through mufflers is plenty for up to 250-300rwkw.
All you get is noise @ that level.
