Looking for ideas to make the car quieter

Talk to tGA. I think he runs a back to back resonators and is around upper 80 db.

I'm running a pair of these Walker Bullet Mufflers in series with a center dump in front of the tank, and I'm usually low- to mid-90s at NHMS. Dyno numbers are "very good".

How much power is lost? How about lost top RPM?
Thanks, MM

Versus what? I've never tested it any other way. No desire to get into any kind of significant development expenses, just wanna race.

But when you do, please pass along the results!

P.S., and no, I'm not spending money at Burns' Stainless; eBay China copies work good enough for me!

The only info I had was from David Vizard's book "how to build HP vol. 1"

He goes into how to test and which brand names had the best results

Walker dynomax, Cyclone sonic, Thrush turbo (all V8 testing)

Stuff like that

Also hot rodding 101 was never use a cherry bomb muffler they are laud and they kill power
