Hy,
anyone know or hear if the 50īs SLIM CASE Mufflers(2,5"):
http://www.flowmastermufflers.com/sh...oducts_id=3364

have nearly the same aggressive sound tone and level like the 40īs-...inside and outside?

Only what i found on the Flowm.site, that the slim case 50īs Deltaflow have an aggressive tone!

Any info would be very helpful.

I had Delta Flow 50 3 chambers on my 72, took them off, interior drone was terrible imo.

We talk about the same Mufflers...50īs Delta Flow (SLIM CASE)...if so,how itīs sound outside ,would they come near the rumble sound from 40īs "at idle"?
Do you know if its a big diff. "at Idle" than the original 50īs Delta Flow?
