Dual Exhaust to Single?

Hey there, ME family

I am not crazy about the raspy highpitched sound coming off my duals on my 3.8

I need guidance on conversion to a single system

Is it a bad idea? Expensive? I don't want to put much into it since I have other more pressing issues for my 2000 convertible.

Basically I just want to lose that tin can, rice-burning sound at higher RPMs

Btw, I don't have much auto experience but my bro-in-law is a pretty good SVT mechanic with Rousch. Haven't ran this by him yet.

Looking forward to your help first. Thanks

What kind of dual set- up do you have? I may be able to help a little. Single conversion is a little pricey

Re: Dual Exhaust to Single?

I believe what you would like is to ditch the H pipe if you have one and instead of an X pipe, create a X pipe with an elongated center made of 3" exhaust pipe. A flow tube of sorts.
This makes a nice size chamber for all 6 cylinders to dump into, equalize and then split into duals.
This way, you hear all 6 cylinders out of BOTH sides of your tail pipes, instead of the 'glug-glug-glug' sound you get with an H pipe.

If thats too much work, you can make a nice 3" X pipe easilly.

I made a few in the past.

X pipes make v6's sound raspy. H pipes give a more rumble sound. What mufflers are you using OP

H pipes make it sound like a redneck truck.

If you get on youtube and look up 94 mustang 3.8 glasspack its a vid of my mustang with dual glasspack side exhaust. I paid 270 and they run straight from the headers back and out the side. No h pipe or x pipe.

This doesn't sound too raspy to me. I think it sounds great.
Mustang V6 2004 with x-pipe and flowmasters - YouTube

just my opinion and all...
don't take the redneck truck thing too seriously.

I know mines custom made, so it's a deep tone all the way thru out the band, I had a friend drive it for the first time so I could hear it, and it sounded mean for a v6, it was deep deep and growled a little, nothing like a v8, but close enough that I'm happy, she got it all the way to re line with it and it didn't sound raspy at all.

Just go to to a salvage yard pull the stock y pipe and by a new flow master 40 to go with it and itll give you some sound but not raspy and shouldnt be expensive

I checked em out. Sounds a little like a bike, different. Not bad, I'll think about that, especially for the price.

Thanks, Scott

MIKE

THAT is what I sound like but I don't even have the deep rumble he's got unless I'm idling or around 1k rpm

I guess it would help to know exactly what my system is comprised of

Re: Dual Exhaust to Single?

Looks like you already have an X pipe into stock mufflers? Or do the muffs say anything on them? Like super turbo or another brand?
You might want to consider new mufflers. If you don't want to hear the engine too much, you might consider stock gt mufflers.
Do you have a recording of this high pitched sound? Kinda shooting in the dark here.

Heres a nice sounding v6. I'd be happy to have this setup.


Hey AK6, can you tell us what size piping you have? It didn't look like 2.5"
The diameter of your exhaust piping has a lot to do with how much of a rumble you can hear.

you should have 2.25 in exhaust pipe, if so then its mostly in the mufflers, you should go with a two chamber mellow muffler to lower the annoying sound down to a normal level so you still maintain sound but at a level that the overall quality of the sound is good. OEM GT mufflers are cheap and do the job for most.

Spector

Great advice. I'm picking up the simplicity of focusing on the mufflers here.

Do the oem gt's need to match my year?

Thanks a lot

Re: Dual Exhaust to Single?

looks like a 1 in 2 out fake dual exhaust...no wonder you have higher rpm rasp....time to go true dual OP....and don't even think about an x pipe lol if you care for your cars sound

as for your mufflers the higher pitch tone could be a tubed style muffler like a thrush turbo or magnaflow...i agree on looking for something chambered.

Its a real X pipe. Notice the two O2 sensors before the X.
