Dump exhaust or no?

foxmustangman · Nov 28, 2008

What is the difference between dumping your exhaust instead of tailpiping it out the back? I've heard that some people like it and other hate it.

It really depends on the mufflers.

I had long tubes with a pro chamber and flows dumped with my built 347 and it wasnt to bad.

On my 93 I have now I had stock headers,mac pro chamber with mac flowpaths dumped and I couldnt stand it. You couldnt have a conversation it was so rumbly.
Now It has prochamber with quiet flows dumped over the axle and its nice.

I want an american thunder cat back.

I had the tailpipes installed back on the car after a couple months. Too much rumble... I like the way mine sounds as it is now, IMO much better.

go with straight tips...dumps sound like crap

If you get quiet muffs, dumped is the way to
go if the local police won't bother you and if it will pass state inspection.
I had em with racing bullets and it really wasn't too bad.

Long tubes, off road x and 3 chambered flows!

I'm really ineterested in this topic which seems to pop up every once in awhile. I have MAC 2.5 shorty headers, h-pipe and mac mufflers and I was thinking about dumping them. Too quiet for my liking.........even though I'm told they are. The rubbing and very little clearence is driving me nuts!!

I got a 306 built with shorty heads and an offroad PC and dumps....

I like it. But with my suspension setup I'm not sure if normal catbacks would even fit anymore.

Who cares if you can talk in the car or not.

Here's a clip

Tailpipes weigh 12 pounds!

I think on a stockish engine it doesn't sound so great, but on a raceir engine it sounds pretty good, but like mentioned it depends on the exhaust setup. Some mufflers just sound horrible dumped, some sound better with'em. Me personally i think i'm sticking with tail pipes from here out.

Yes and no.
While it can sound bad with certain muff's it can also sound very good with others.

Adding a cam is a sure fire way to make most muff's sound good. Like Doc's.
Im a fan of dump's.

Yeah that's what i'm sayin...i wouldn't consider my engine a race engine but it's not stock...just the more power an engine makes, the better it's gonna sound.

The more air you can cram "in" makes for a sweeter sounding coming "out".

The only two configurations where I've heard Dynomax Super Turbos sound good is either behind an off-road H-pipe (not X) with the side-exit design (inlet/outlet on same side) or dumped after an off-road H. Anything else, and they're just too damned quiet and tame in tone. The H makes the tone right, and with dumps or side-exits, they've got the right amount of rumble and no drone ... although the fumes rolling into the interior when you're at a stoplight can be kind of annoying.

dumps=drone=me no likey

25thmustang · Nov 29, 2008

I run dumps currently. I prefer tailpipes but dumps were easier at the time.
