The Stovebolt Site Forums The Shop Area Engine Shop loud pipes

This will sound like a strange question: My 65 has dual pipes that are way too loud--would be perfect for a teenager but it's a long time since I was there...these are newly put on by PO. Is there bafflers I can put in or something else besides putting in a different type? They are all one piece -front to back--has a 350 engine and was set up as a muscle truck.
Thanks!

Redtruck,. the best way to tone down an exhaust imho, would be to swap out the mufflers. You are probably running 2 chamber Flowmasters or some other brand that makes the exhaust gas pulses ring out! My 69 Camaro has the 2-chamber Flowmasters and I probably should have went with 3 chambers or some other type alltogether... I don't know of a good way to tone down without physically changing the mufflers out. Maybe someone else with good info can chime in...

You need to change the mufflers. I use 30 in. glasspacks with 2 in pipes. Sounds great. A little deep rumble but no excess noise. If you have real large pipes you may want to go with stock mufflers. Either way they are much cheaper than the Flowmasters or similar mufflers.

I would have to cut the pipes or take the whole thing out. They are new--maybe someone would like to buy them.

Stop by your Pep Boys, Auto Zone, etc., they have exhaust pipe reducers, and more. You should be able to cut the mufflers and fit something else in.

So you're saying it has no mufflers, just straight pipe? Go to a muffler shop and have them install Flowmaster 50's just before the tailpipes go up and over the rearend. It will be a nice mellow tone unless you're really standing on it.

Thanks Larry, I'll try that.

bigtrucks, It does have mufflers just behind the axel--I think they are Flowmaster--they are welded togather. As Larry said I can cut them off and add something else. Can bafflers be put in like they use on motorcycle pipes?

Take your truck to your favorite muffler shop and tell them what you want it to sound like. An experienced guy will know what to do.

I installed 1 7/8" duals with glasspacks to my 57 235 with Fenton headers. That was way to loud. I replaced the glass packs with Flowmaster 40's and I love the new sound. It's rumbly but not to loud.

I had 64 SS chevy ran twin 2.5" straights really loud. When you got to town on Sat. night you could put a metal chore girl in each pipe with screen wire over the end to keep it in. Worked really good for about 3 hours or so this trick worked good on open headers too.

Something else you could consider, since the mufflers are aft of the axle, would be the Kerker SuperTrapp muffler. Their basically an oversized off road motorcycle muffler. They use diffuser disks to muffle the noise and are tunable by adding or subtracting the disks. http://www.supertrapp.com/product_sections/cat.asp?CatID=31

I had a supertrapp on a street bike. They are nice for low CC engines. Nice sound, much different than anything out there. I've never heard them on a truck / car engine before... other than a VW dune buggy.

If you ran dual pipes all the way to the back and put on a pair of these that would be interesting, might work real well. They make larger versions of them for larger engines.

The tunable aspect is VERY nice. Less discs, more torque, more low rpm torque. More discs, more HP, more high rpm power.

I don't know how rugged they are. They might not stand up to a daily driver use.

They're not cheap.

They were popular in the 80's on hot rods and pro-street cars before the Flo-Masters came along. They were originally made for off road dirt bikes and atvs, so they are very rugged. You're right though, not cheap. I only threw it out as a suggestion/ alternative to Flow-master.

Thanks guys
I'll look into those mufflers and if not way too expensive give them a try.
This forum is amazing--a great motivation kicker. Now I can really live by my motto and when something seems impossible just start doing it.
Way to go!!!!

If the exhaust has a really distinctive 'rap' check to see if there is a crossover ( or balance) pipe , it needs to be near the front of the system.

Having a balance pipe helps economy too -
