v6 exhaust? - Page 2

Anybody ever try an X-pipe on a V-6? They do seem to blend the exhaust pulses together on V-8s for less of a distinct rumble. Maybe what a V-6 exhaust needs is something of this order to "fill in the gaps" of the missing 2 cylinders.

You mean a FORD v6. I know of gm's mostly any muffler (besides glasspacks, flowmaster 40 series and cherry bombs) dont sound bad. I believe it is the firing order on the car in question is why anything will sound like crap. Just like the way you can tell the difference between a stock. 5.0 with flowmasters and a stock 4.6 with same muffler also.

But gerald, you might be right , that may help it out some.

no, it will still sound like ass. Greg has a prochamber on his I think, and it sounded like straight shit. If you leave the cats on, it wont be too terrible.

Does not matter what the firing order is or the manufacturer. V6's sound like crap, period. I've heard many of them, different makes, and they all sound terrible.
I love Buick GN's, but if I had one I'd make it as quiet as possible b/c they sound like crap too.
Some sound OK while idling, almost like a V8, but as soon as you crack the throttle there is no mistaking how many holes are firing.

I don't know. The V6 in the GT1 car sounds pretty killer. Of course it is breathing through equal length long tubes and a 5" straight through muffler turned down under the car. Loud as ballz inside the car, though. Still sounds sweet at 7500-8500 revs.

Hal's comment on GM V-6 exhaust systems sounding decent just gave me an idea. Most of the V-6 GM cars I have noticed run a Y pipe up front with a single feed into one muffler, and dual out the tailpipes from there.

Try this out. Up front use a Flowmaster 2 into 1 collector to form your Y-pipe up front. The Flowmaster 2 into 1 collector has a 3" outlet. Run a single 3" pipe from there into a single 3" muffler of your choice. One 3" pipe flows just about as good as dual 2-1/4" pipes, as the total cross sectional area is nearly the same. Dual it out AFTER the muffler to keep your dual look at the rear of the car.

Way back when I had my supercharged 5.0 1993 F150 longbed, this was how I ran the exhaust. It ended up sounding identical to a 5.0 mustang. All the other longbed trucks at the time with a 5.0 Mustang powerplant with true duals did not sound near as good as the same motor would in a Fox body. After my truck's big single exhaust sound came out identical in sound to a true dual Fox body 5.0, a bunch of us came to the conclusion that the reason why truck true dual systems always sounded different was due to the longer run of pipe.

I believe your best bet is to run both sides of your engine into a single muffler and dual out from there.

With a v6? I think a turbo sounds the best.
