Re: What muffler on a 4.3 sounds good

What version Flowmaster do you have? The only what to get a V8 sound is by dropping in a V8.. Our 6 bangers have their own sound.. Go with a Flow 40 series<a target="_blank" href=http://www.flowmastermufflers.com/web10/productsf5.html>http://www.flowmastermufflers.com/web10/productsf5.html</a>, open up the pipe after the cat to 2 1/4", Replace cat with high flow, JBA headers, And finally throw a tip on the end so it trumpets the exhaust sound.. Now every cop in town will hear you coming and your neighbors will hate you..[img]images/icons/wink.gif[/img]

Depending on your local laws and how <font color=green>green</font color=green> you are.. Opening up the cat does give it a lower tone and some volume.. Not sure why I know that.. [img]images/icons/blush.gif[/img][img]images/icons/wink.gif[/img]

Re: What muffler on a 4.3 sounds good

if you want it truely good and loud....don't put a muffler on. leave the cat but no muffler at all. i did that and it sounded great. fyi - i have 3" pipes though. it was soo loud that i couldn't hear the engine, so i put a flowmaster series 40 on it. good sound but honestly pretty quiet compared to the old sound. but now i can hear if something is going foul.
