Allright, ive been thinking of the true duals over/under the axle for a long time now. i think i want to do it with the stock manifolds and cats or whatever then go back from there. my question is about how it will sound compared to other vehicles.

One of my friends has a 99 TA with a loudmouth.

The other friend has a 2002 TA WS6 with : longtube slp's, highflow cats, Ypipe right into a corsa.

My cousin has a 2000 or 2001 silverado with the 327, he has duals with each pipe having like a 20 inch glasspack.

Will mine sound like any one of those? Louder? More Aggressive?

 

it will probably sound most like the LM or the truck.

the corsa will be much more refined due to the muffler.

it will depend on what muffers you use and if you do an H or X pipe.

 

there are vids with sounds at true duals

that should help ya..

 

"True Duals" means true duals...not an x or h pipe..its not the same...yea itll flow better then an exhaust without one, but dual exhaust means tubing coming off the header into a muffler..one for each bank....and let me tell you TRUE Duals sound 10X better then an x pipe of h setup...you can actually hear/feel the harmonics of the exhaust pulses under the car...that is soooooo friggin sexy...


That white formula sounds the meanest

 

well man...then i guess you better correct the hundreds of guys on the board who are running X and H pipes and are considering them "true duals"

while you're at it, correct the handfull of companies who are designing, building and selling exhaust systems with X or H pipes and listing them as "true duals"

i think it is you my friend who is mistaken

there is still a pipe for each bank, but there is power to be gained from adding the X or H

wow..would you look at that..true duals that have an X pipe

i'm curious what you think these systems should be called

 

true duals means "true duals" and not X or H :-)

not trying to sound smart but........can you imagine sidepipes with a X or H pipe ? The sound is different....

 

True duals means two pipes that leave the manifolds/headers and have 2 mufflers (one for each pipe). You can throw an h or x pipe in there to equalize exhaust pressure between the different cylinder banks increasing in an increase in hp most of the time.

The alternative is a y-pipe system where the pipes leave the manifolds/headers and merge into one pipe running to one muffler then it can either split back into two pipes or not.

The reason people call them TRUE duals with f-body's is because the factory exhaust has two outlets and appears to be dual exhaust but is not so when people have dual exhaust on an f-body they say they have true duals.

Now as for the original posters question I would say it would probably sound most like your cousin's truck since it is the same exhaust and similar engine.

 

I didn't mean to sound smart when I said that it doesn't mean X or H or Y..... but look at the setup that we have in our LS1s, the Y-pipe kills the sound - and I do not mean noise or HP losses.... a true dual setup will sound great, actually "true", I'm currently building one: emission legal with the catalyc converters and trying to make it over the rear axle (BMR has a kit that provides additional clearance)... I'm more into the real V8 sound than into 5 or 10 HP gains which the H or X pipe will give me... hey, I'll post again once my setup is done...

 

I'm having a little trouble following what you are saying.
What are you saying here? No one said a y-pipe was a dual exhaust system, and if you say it kills the sound then you do mean noise.If you listened to the clips in the link psycho posted you would see you can have the best of both worlds.

 

i just really heard the TA with the long tubes my friend has and its really not that great with the y pipe. the truck im talking about has absolutely no connections between pipes, and i can tell you it sounds bad *** buddy. i hope it sounds like that. Puttying the H in the pipe for 10 horsepower doesnt sound as inticing as the sound of TRUE duals. 10 horsepower wont gain you that much anyway.

 

theres 3 posts in a row from people who need to be corrected

like WE just said..True Dual exhaust means no crossover of anysort...it will never sound the same...itll help scavenging and add some ponies, but if theres a crossover it aint a true dual..

 

Wow, of all the posts I've read on this board this is the first time I have seen anyone say that having an h or x pipe is not a dual exhaust. Whatever, I'm not going to argue about it it's all terminology anyway. So if you insist on saying dual exhaust can't have an h or x pipe fine, but there are a lot of other people out there who will need to be informed of this new rule.

 

there's a pipe for each header

there's a muffler for each pipe

what's not "dual" about that???

 

I agree with mullet and teke... You guys are nuts. Try telling every 03/04 Cobra owner they do not have a "True-dual" exhaust system because they have an H-pipe. A crossover is simply a complement to the true-dual setup .. If you guys can't see it that way on the basis that the sound changes, you need to go get a cat-scan

 

true duals are just that. True. No connection, if they are connected they are just duals right?
