Ok so I was talking to a friend of mine about exhaust options. He claims
that crossover pipes (H-pipe, or X-pipe) is not really true dual exhaust
and doesn't sound as good as two seperate pipes with cats on each pipe. My
question is, which sounds better, and which adds more power? Crossover
pipes, or what he claims to be True dual exhaust. I know most H and X
pipes add around 20-30hp or so. I have no idea what the seperate pipes
would add. I want to have a good, loud sounding exhaust, but of course one
that adds some performance as well. I was expecting to spend around 700$ on
a Bassani X-Pipe and then maybe some Flowmaster 40 series, but he says you
can do the seperate pipes for much less. What is your take on this?
Thanks for any input
Finally an option for me...I don't not have an un-idea, but it doesn't not
sound cool :laughing:
I can help though, to visualize:Bassani X-Pipe:
I don't know much on exhausts, so...I can't offer any input :ohcrap:
if h-pipes and x-pipes didn't work any better, people probably wouldn't do them, b/c they can be a pita to install (non premade, at least...)
I could be wrong, but wouldn't the straight dual exhaust be better
cause of the fact it has no major bends or kinks to block gasses?
but i dunno about sound, mufflers and the material of the pipes will determine
this id say:2cents:
I thought x pipes gave maximum flow. of course Im wrong alot
:thumbs: Yes I am still unsure as well, so hopefully someone knowledgable such as ChrisV will hopefully come and shed some light on this mystery.
i still vote true dual for most power:mrgreen:
comon someone who knows for sure....
Straight pipes with no kittys.
yea i'm pretty sure garfield cant help exhaust systems... :laughing:
Properly tuned crossover will give better response and better sound.
that's what i'm saying... google it, people...
Google schmoogle, it's a well known fact in performance circles.
I must admit though I have never considered a 20-30hp gain. What it does do is flatten the power curve.
I was referring to crank power, and thanks for the info wally.
i'm saying google for those folks w/o reliable performance circles...:wink2:
The difference between the two would be backpressure for low end torque.
True dual with straight pipes would sound amazingly tough but at the
expense of losing low end torque yet gaining minimal amounts of top end
I wouldn't say there is a better or worse just a trade off depending on your setup and driving style. Of course if you are FI that is a whole different ballgame.
BTW: Crossover or not it is still considered a "true dual" A contrary example would be my car. A transverse mounted engine with a crossover connecting both mani's to a single downpipe then to a Y out to dual exhaust <-- not a "true dual"
The crossover pipe equalizes the exhaust pulses, and aids in scavanging.
This smooths out throttle response and increases low end power, while
providing enough tailpipe to not hurt top end power. It's the same
principle as using a collector at the header vs individual tubes per
exhaust port going all the way back.
Race cars that only use full throttle and higher rpms can get away with individual exhaust pipes, but cars that use their full rpm range need scavanging, and benefit from crossovers.
