My 67 with the Indy crate 360,i have tti headers(nice fit!!!) I've always loved the sound of the short glass packs, I'm going to run 2 1/2" do you think you lose power with glass packs over flomasters, or is it just preference on sound?
 
For the most part, a full bodied muffler will make more power then a glasspack with the same input/output diameter in my experience. And i don't personally care for glasspack's. But with that said, i don't know that there is enough difference if you really like the GP sound?



P.S. Just to clarify, What I was getting at on the in/out comment above was, that years ago even with a 2 1/2" glasspack, the core diameter was usually reduced to keep them from being crazy loud. I'm not sure about the ones available today?
 
you probably wont notice +/- 3 horsepower to be honest. you are counting hairs on a mosquito's *** at this point.
 
"witch way to go?"

I would go the way this witch wanted me to go.

use most any modern glasspack and you wont lose any power,look at borla,dynatech,dynomax,Magnaflow for alternatives. flowmasters usualy cost alitle power and might cost your mind.
 
Glasspacks would be a waste of some really nice Headers.

TTi's and Magnaflows .....Now your cooking with gas !!!!

i dont think youll lose any power.there are some really nice gp mufflers out there if you know where to look.jones exhaust makes some with a great core design that flows well,summit sells them in a bunch of different configurations for a fair price.if your interested ive got a few different sets of gp style mufflers on the shelf,some of which i made.including a set of stainless steel packs and a set chambered mufflers....and well just about everything else you can think of.

Call it what you want...Magnaflows dont go WaaPaaaPaPaaaa when you let off the gas. Sounds great on a low rider, not a Muscle Car.:D

depends on the application...true dual(no crossover) 1.75" or 2" pipes with some long cherry bombs on a low comp chevy 350 gives the sound you describe.and i agree it belongs on a low rider.however dual 2.5" or 3" with an x-pipe with a set of dynomax bullets or jones thunderbolts on a mopar sb with some cam and compression will have a different note....

Spiral mufflers they r an inline muffler so it looks like a straight pipe on the outside but when u r driving it has a snarly sound in normal driving but binder hard accelerations and upper rpm range it is a completely unreal sound . I use these in my big block 67 and on my v10 ram both have 3.5 inch exhaust
