you won't get sleeper status. Too much airflow going through there. I was at 115-dB. Now at 90 dB. I really wish the phone app allowed for video posting.

Probably have to go with something more restrictive and cutouts if you want a true sleeper. Though I saw somebody else posted up about some other mufflers on this thread that were quieter

Hard to even tell the difference but both sound great!!! Definitely not quiet with the new setup, just not crazy loud anymore. My neighbors are already used to my stuff so hopefully I'll be ok when I get mine together.

Yeah, the vids don't really show much difference, but 115 to 90 dB is a huge difference. My neighbor across the street said he didn't know it was running until I came over to ask him if it was ok and he heard it when he opened the door. The little kids next door could stand behind it, where before they were covering their ears 500-ft away.

I doubt I lost that much to be honest. Air velocity is still very good coming through the tips

my neighbors love my cars sound. Though, I'm very mindful of them when driving late.
car sounds good, not a great difference in tone.

Sounds slow.

My neighbor kids stop what they're doing and walk to my yard when I back the car out lol. It's so funny and their mom said "you know they think you're like the coolest guy ever?" I'll take that

Sounds great man, can't wait to get mine back on the ground!

Ahhhhhh....

Thanks for the ear candy this morning Darth. I want to quiet my Nova down as well, I recently moved from an apt to a nice quiet residential neighborhood without a hotrod in sight I was wondering what mufflers to go to without restricting my HP or airflow any. Currently have Flowmaster deltaflow 40's.
