Dual exhaust conversion question for V6

ohtwoV6stang · 10-01-2009

I have an '02 V6..im going to put on a MAC off road H pipe and MAC GT cat back exhaust system. will i need dual exhaust hanger kit since it a V6? and has anyone heard the combo im going for on a v6? any help appreciated

If your going to go to the extent as to get dual exhaust I would advice just going to a shop and having them custom do your piping. That way you can increase pipe diameter freely, and pick whatever kind of muffler and tips you want. Also, I'm not sure about this but I don't beleive you can use a GT kit on a V6. I beleive the positions that the headers stop at are different so things don't fit right.

as long as you buy the v6 midpipe it will work fine and then i believe you can hook any gt catback exhaust to it.. i do know you will need hangers for the right tailpipe since theres nothing there on the v6 model.. im not sure if hangers would be included or if youd have to get them through some other means.

+1 and ya just go ahead and buy set of hangers... but just out of curiosity why h-pipe and not x-pipe?

x-pipes often give the exhaust a sort of raspy sound while h-pipes are deeper

ya I've heard, but don't H-pipes loose a little efficiency after 3-3.5k rpms?? where as x-pipes do not?

maybe I've heard wrong

yeah i ahave heard that too. Im only 17 so i dont have alot of money(hence why im going with MAC) and mac is the cheapest exhaust supplier for a V6 and they only make an o/r H pipe for the sixer. and i would rather have a deeper sound and o/r midpipes are o/r midpipes..

Indeed, H-pipes aren't as efficient at high rpms - the air just can't make that tight 90-deg turn at high speeds, and so all the air get rammed down one side (instead of flowing freely thru both sides, like in the X-pipe). However, the effect is minimal: 1-3 hp loss compared to an X-pipe, so most people choose the H-pipe for cost (cheaper, more available) or sound (deeper).

As far as the hangers - most kits come with them. If not, I think AM (american muscle) has them for sale in their exhaust section...

is divorced better than x and h pipe?

if i had to guess considering what silver J just said.. it would be about the same as an H-pipe.. possibly slightly better since it flows straight through rather than hitting turbulence as it tries to make that 90 degree turn.. also putting my little bit of aerodynamics knowledge into the situation.. it would flow slightly better (less turbulence = more laminar flow which is faster and straighter with less friction).. and usually better flow = more hp.. so take that for what you think its worth

Pretty much right... the true duals will probably flow similar to the X-pipe, since there are no bends. However it's path doesn't expand (like an X-pipe), so the cooling air keeps traveling along the same tube instead of being able to split and exit out two tubes. But it's such a small difference, I don't think you'd notice.

True duals have a tendency to pop, cuz even though our engines are even firing (and don't really need the balancing mid-pipe), each side is still firing exhaust blasts independently, though very quickly. The mid-pipes kinda balance out the sound. I do believe that true duals are the loudest, since there is very minimal restriction from bends.

I have divorced duals and it does like to be poppy when you rev it up and let off. It sounds mean as heck right through 2-3.5K.
You can get a shop to fabricate a set of duals with an H or no cross over for $400 or so if you shop around. That is even cheaper than a catback kit.
