V6 Exhaust

Samuel1881 · March 30th, 2008, 10:02 PM

On my 2004 v6 mustang I have dual flowmaster exhaust. However, it is still lacking in how it sounds. Below 2000 rpm it sounds fine, quiet but fine, once you reach 2500 rpm's or higher it looses that good rumble. Is there anything you can recommend I do to improve how my v6 sounds? As a side note I am considering removing my catallitic converters and running straight pipes into the flowmaster mufflers, any thoughts on this idea?

I would say cam it, intake, and new heads. Im sure someone else will have a different, less expensive idea, but with the cams, intake, and heads, you will see a deeper sound and better performance.

cams, intake heads and many more!

what about removing the cats?

jdansby1 · March 30th, 2008, 10:32 PM

My new set-up wont have cats, but some will argue that having high slowing cats will give it a better sound.

Samuel1881 · March 30th, 2008, 10:39 PM

Ok, thank you. How do you think it would sound if i removed the cats and had straight pipes into flows and, would I have to do anything to the computer?

you'll have to get mil eliminators at least

flows, no cats, x pipe.

Not a huge fan myself.

thanks. sorry to be a dumbass but what is a x-pipe

ItaliStang · March 30th, 2008, 11:44 PM

Hpipe... BBK Shorty H-Pipe (96-04 Off-Road)

X-pipe... Pypes 409 Stainless Steel Off-Road X-Pipe (96-04 V6)

(for a gt though, dont get these if you have a sixer, just using for example)

it's the midpipe that connects from your headers to your cat-back

A stock v6 has a y-pipe at the end of the catalytic(sp?) converters.

An x pipe usually, from my experience, eliminates the cats and has a X crossover creating a true dual set up.

ItaliStang · March 30th, 2008, 11:49 PM

you can get catted x pipes...

if you need to pass inspection...

otherwise, don't bother

jdansby1 · March 30th, 2008, 11:51 PM

You can, but like you said, dont bother, haha. Alot of places will pass without the cats aslong as you have mufflers. Such as the set up I went with. O/r x and pypes violator catback.

Pypes 409 Stainless Steel Violator Catback with Polished 304 Tips (98-04 GT)
