The Stovebolt Site Forums The Shop Area Engine Shop What do 292 owners run ~ muffler for a 292 w/ Split 3+3 exh.

Hi guyz, it's good to be back online again.
I'm sure this has been hashed over so I'll do a check and search...
But
I'm gathering what I need to finish w/ the engine/drivetrain install. I'd like to put a quiet set of mufflers in this 3100 w/ a fairly stock 292. I have Langdon's split 3+3 headers and if my old memory serves me now I think he says NOT to install flowmasters. I think I've also heard they don't sound or work v-well w/ L6's, better for V8's, any. So what is a good muffler to use that's quiet. I believe I should run a crossover but I'm letting the mufflerman do that end of it. I also have a 500 edelbrock & clifford. I believe I should use 1.75'' pipe?? Another question is should the mufflers go closer to the engine or towards the axle?? Does that make a difference?? why?? Is there a way to have the two mufflers come out of one pipe right at the end. I really love the sleeper look. I don't really know what ''a classic sound'' or ''rap-rap'' is that's used in advertising mufflers. Any insites guys??
thanks for the help.

If you want to keep the Chevy six rap-rap sound, don't use a crossover. The closer the mufflers are to the rear the less cab noise you have, and they usually stay cooler and will last longer. I like the sound of Dynomax Super Turbos, not as loud as the flowmasters, but louder than stock. If you want quiet, you need to go with a stock Walker muffler. A good exhaust man will be able to answer a lot of the questions you have.

OK
Let me ask this... who has a 292 and what muffler do you run under your truck and how do you like it
dual or single exhaust tailpipes???
do you run a crossover??

On my '65, I'm using long tube headers with 1.75 pipes all the way out to the bumper. I've got 24" glasspacks under the bed, just forward of the coil springs. No x-over, just straight pipes coming off the headers. Normal driving isn't loud but, if I romp on the accelerator it gets pretty loud. I actually love the sound when the secondaries open up . I have a hard time staying off the gas 'cause it sounds cool which of course gets expensive.
If you want all quiet, all the time then yeah, look into the Walker: quiet mufflers

I prefer the huge walker mufflers on my 292 because I frequently pull a stock trailer through the mountains with lots of third gear and I like it quieter. Jim

caroline,

You're a relative newcomer and were not around the 2 or 3 years ago when I built my 292 (and bothered everybody here darn near to death! ) I have my engine in a 1966 shortbed stepside pickup and run the extra long 36 inch tube headers. The exhaust is joined together about a foot past the 2 1/2 inch header collectors by a makeshift welded "Y" pipe. The single pipe is 3 inches in diameter and goes into a single-in/dual-out FlowMaster 40 series muffler.

I like the results and look forward to doing a similar setup on my next engine. Only thing I'll do differently next time is use a smaller diameter muffler inlet (maybe 2 1/2 inches instead of 3 inches). The sound is different for a straight 6 (Woogeroo has heard it). Not a typical 6 cylinder sound at all. Most people think it's a stock small block. The exhaust note gets slightly raspy when you punch it really hard and hold it. On normal acceleration the exhaust stays deep and low. Just like I want it.
