Do resonator hurt flow?

[Nomad666]

Just wanted to know if resonators hurt flow at all? I know they quite the exhaust down but dont really understand how. THANX

Yep, they hurt flow. But not a great deal.

I plan on having a nice LOOOOONG resonator put on to cut my noise down a lot.

That way I can put my test pipe back on and it wont sound horrible, plus the increase in flow from the tst pipe will counter-act the loss due to the resonator.

Why can't you just put the resonator in place of the tespipe(no cat back)?

my dynomax catback has a resonator on it. Muffler shop is going to take it out for me and weld a pipe for 40 bucks.

res. is a restriction, any restriction hurts flow.....

There are two types of resonators:
Louvered Core
&
Perforated Core

The latter of the two (perf) is the one you want. They present no (or might as well be none) restriction.

i got a test pipe with resonator but not a strait thru muffler so wanna take out my resonator and see how much louder or rumbly i can get it. If anything i would change the dynomax muffler for like an apex n1 universal or something like that and keep the mandrel catback.
