I Have a 1980 silverado with 350 in it right now it has flowmaster muffs and has cats.. ima pull of the cats hoping that will make it louder if thats not enough what can i do to make it LLLOOOUUUDDD
wanna bug the neighbors.!! 
Thanks guys!

I have headers and duals, replacing the muffs with pipe makes it A LOT louder, but here in CT not legal so I went back to mufflers. Now I have cut outs, so when I need the truck loud I take off 6 wing nuts and my truck is loud. You could try keepin the cats, and removing the muffs and replacing with pipe. That way the cats will quiet it a little. If you not worried about being too loud, go with open headers, nothin louder than that!

open headers are definetly the loudest! just run straight pipes, no mufflers or cats. the neighbors will here you comming from blocks away. my buddy had;em like that on his 4 banger s10. we knew he was comming about 2-3 minutes before he got to us.

2 chamber flowmasters..............
-
purple horny glasspacks
-
I'd say straight pipes. With turndowns after where the mufflers would normally be if there were any (just after the back of the cab).

Im not sure if you guys watch the show "Trucks" but on the project "Copperhead" they are running a "Y" off each of the headers and running dual exhaust, with muflers and just your basic regular exhaust setup, and the other part of the "Y" is straight piped out the side off the headers. The "Y" has a butterfly-like setup you can buy from Jegs or any aftermarket shop and it runs to a switch inside the truck and he can flip from regular exhaust or over to open headers. Its quite the setup, insane! Go to www.Trucks.com to check it out

glasspacks are old and sound gay.........get some 2 chamber flowmasters and dump the exhaust before the rearend......sounds tough.
Toys are my game

rsbad454 you r right glass packs are gay
i have a 350 also and this is what i did . headers in to true dual 2.5 inch pipe with no cats and 2 chamber flowmasters that run all the way back and then dumps behind the rear tire wiht an angled cut chrome tip that i had bent at the muffler shop so taht you could not see the weld . turn downs are also gay and strait out the back is played out. my exhaust sounds really nice and loud too but it also does not have that popping stupid sound taht you get from haveing too big of a pipe . if you wnat something classy and loud o with something simmalar to my set up.

i dont see the need to be loud ... espically with glass packs or strait pipe.... i run a full exaust with cats and muffs.... with it exiting in front of the rear wheels... and i cant creep up on a def man... i just say have a little more class and go with an origional setup... dont let em know ur comin until u rev it...

I have a 6.2 Diesel with headers and only about 4ft of straight pipe on each side!
EXTREMELY LOUD!
-
ive got headman long tube header, no cats (for now they started emissions up again in ct), and flow masters 40 series. oh ya and im running true dual and my truck is very loud!!!! I had the truck on the road for a little bit a few months ago and i was putting harleys to shame.
-
I have headmen headers 2.5" pipe with 40 series flowmasters with a h-pipe( this makes it quieter evens flow) no cat( you can still get through sniffer tests without cats ). This isnt a quiet system . I run my exhaust all the way out the rear bumper. The h-pipe makes it alot quieter( because it balances the flow) and improves lowend torque. running it to the rear axels will make it loud in the cab. Maybe not loud outside but loud in the cab. Myself loud in the cab gets old fast. Running the pipes out the rear bumper the sound goes outside not in the truck. Edited by: 78chevstepside at: 12/24/03 6:22 pm

I dont like TO loud either. Ive always felt if its THAT loud, it better be awful fast..& most arent.
Im runnin Sanderson shorty headers, 2.5" exhaust with Dynomax turbos , with Vettes tips through the roll pan. its alot quietr than many that are much slower.
-
I have open headers on my 82 custom delux i put the 3in to
2 1/2 in conversion that came with the headers on and they sound even better!!!
-
Bigger pipe can usually make for deeper, louder tones than smaller pipe. If you don't want to be totally ghetto by running open headers, you could do dual 2.5" straight pipe with turndowns. Be wicked loud outside AND inside. Or even go with dual 3" if you want to lose a lot of torque. I'd say go with the electrically-operated cut-outs (what Copperhead has). Flip the switch and be LOUD.
I got some vids of my old Dakota R/T that had a gutted 3" cat, 3" straight pipe to a Flowmaster 3 chamber with dual 2.5" out to Megs tips, centered under the roll pan shotgun-style if you want to hear what that is like.
