H or X are best, then true dual, then Y. duals off the Y pipe are very restrictive, and you will only get a different note. the H is deeper and X and H flow evenly on our even-firing motors.

I suggest mac long tubes, short off road H pipe, and cat back for the GT of the same year to all bolt up and sound/flow the best with gains exceeding 25rwhp

Get a system with a H or X pipe then your choice of dual exhaust catback. The 6's sound a lot better with this type of setup then a true dual with no crossover. You either can get shortie headers and a direct replacement offroad h pipe to meet those or get longtubes and an offroad/catted H or X pipe and from their you choose your catback. MAC longtubes would be the best route to go and start with __________________ New block with forged internals running 16psi, tuned by Lasota Racing Too many mods to list... 3.73's and Truetrac Finally Done!

Sorry to hijack, but the cross over what would it do I have heard good things and am considering getting it over Christmas.

Makes it sound better too since we have even fire motors. I wonder if their are any non even fire six's in existance and if so i wonder if you could make one of those sound more like a v8...

... aight im a little retarded when it comes to electrical work about the enigne... what controls the even fireing... and isn't that controlled by the coil pack... is it different from single fireing?

lol oh wow. it has nothing to do with anything electrical. It refers to the way the pistons fire. To try and explain it easier. V6 mustang engines are even fire as are pretty much all 4 cylinders known to man. Which is why are engines sound ricey above like 3500rpm. In our v6's a piston fires every 120 degrees rotation of the crankshaft. With the the V8's they all fire at random degree intervals which give them their distinct sound. there also known as "odd-fire". This is also why it is impossible to ever make a v6 mustang sound like a v8 equivalent.

Here is it in technical terms:
"An even-fire engine is one in which the firing of each cylinder is separated from its predecessor by the same angular travel of the crankshaft. An odd-fire engine is one in which each cylinder fires at a different rotational spacing from its predecessor."

ours fire like this
1-4-2-5-3-6
and this is what our engine looks like
3-6
2-5
1-4

the odd fire is something like this
1-7-2-4-6-3-5-8
and this is what their engine looks like
4-8
3-7
2-6
1-5

make sense?

i have a question. since y pipes are so restrictive then why do f-bodies (camaros and firebirds/trans am's) use them?

97tunedmustang hit the nail on the head but my way is a bit more user friendly to someone who doesnt under stand what he meant. im just backing his post up.

so more money can be spent on the aftermarket? Chevy/Ford love to put stuff on cars that you will replace! Just a way to make alot of money...Restrictive so you buy more, or at least that is my way of looking at it!

It doesnt really matter that much in what order their firing, but the timing between each fire that signifies and determines whether its an evenfire or oddfire engine.

Two V6 engines have the same firing order 1 6 5 4 3 2

-One has a piston fire every 120 degrees of crankshaft rotation, this would be an even fire motor.

-One has a piston fire in this sequence. every 150, 90, 150, 90, 150, 90 degrees. this would illustrate an odd fire engine.

Both have same firing orders just different intervals between each piston fire.

Also an answer to your question about the y-pipes used on camaros, firebirds, and trans am's is due to the way the undercarriage was made on the vehicles it is virtually impossible to run a dual exhaust. It must of been a collaborative effort to design all these vehicles at the time to only work with a y pipe exhaust setup. If you look at the underneath of one of these cars youll see there are ares designed to route the stock exhaust, which youll notice cut quite obtrusively into the passenger footwell, and because of this prevent you from ever running a real dual exhaust out of without having the pipes be practically resting on the asphalt.

srry didnt even see this post..

but normally...it wont be exactly there
and sadly since yours is a custom exhaust like mine..long tubes are either guna have to be done by a muffler shop,or your gunna spend some time under the car cutting, welding and fitting

but the cross over tube is rather easy to do with the right tools

they have clearance issues and sit lower to the ground, the few nasty times i have driven a camaro ss and firehawk you feel like you are laying down, to me

usually this is the breakdown for the duals or single exhaust setup:
