    Exotic Sound on a Budget

    thought i would bring this up again to see if anybody has any new suggestions. we are not talking bmw m5 engines or similar. lets keep this geared to budget solutions. ie, budget engines, exhaust mods, electronic sound mimickers ect. this thread is for comparisons and ideas, not arguing. we can never clone the ferrari or lambo sounds in our cars but we can make them sound exotic.

    I really like the 2.8 from Tiawan, the first video I thought was a dub over because it sounds like a Ferrari and it even has a "gear change" sound that wouldn't happen if you were just free revving it. But the second one sounds the same. SO unless he was able to sync his hand revving the throttle to a Ferrari sound track, it could be legit and VERY interesting! What did you stumble across?

    i dont want to spill the beans yet in case it doesnt work. but i will see if it makes the 2.8 sound less like a tractor or industrial generator and more like a performance v6.

    hint: if you youtube, "elh wrx" or "elh sti" you will get part of the puzzle.

    I owned a 545i, sold it for a x5 now. regret it. A few weeks after I sold it, i found this video online. meanest v8 sound ever.
    What do the bmw v8's run for? Cant be that expensive, a used 545 can be found for 15k now. Makes me wonder...

    Thats funny you mention Equal Length Headers. When I built up my1/4 mile car I worked with an exhaust guy who lived and died by the ELH theory. Well I blew it off and bought some off the shelf headers for my Talon. Pulled good numbers with it but when I finally saved up for a custom header setup with the ELH theory, I pulled 14 whp out of it and the sound was unbelievable. I also hit full boost on my turbo at 300 rpms faster! Dude it was night and day difference.

    The reason I keep calling it a theory is because with some cars It actually does the opposite. But in my case it worked great! You see with different length exhaust headers, wave lengths will vary among each cylinder. This causes different tuning requirements for different cylinders. This obviously will affect air/fuel mixtures and timing requirements, and can make it very hard to achieve optimal tuning. Equal length header tubes eliminate these exhaust-induced difficulties. It makes every cylinder equal. Tuning maps are much smoother. These are huge in the Import scene especially in the WRX scene as you mentioned.

    Im going to try this on the 2.8 to see what happens. Good find Twilight!

    If someone had ELH for the 2.8 it would be a top seller among Fiero and replica owners. DO IT! ;D

    if i had the money i would in a heart beat.
    i feel equal length headers would solve about 30% of smoothing/evening out the exhaust pulses.
    i will skip the hunch/theory i have about another piece of the exhaust puzzle and deal with the end of it. the exit. if you speed up the velocity that the gasses exit the tips, the pitch should raise. i experienced this with my 350z. there are a few ways to accomplish this task.

    1.taper the diameter down approaching the exit.(this seems restrictive so probably wouldnt help hp)

    2.go large diameter tubing onto a large chamber(basically a muffler shell with no baffles inside) and exit with single or dual smaller diameter tubing. the gas would collect in the chamber and be forced to speed up as it exited the tip or tips.

    3.build a muffler that cancels out mid and low frequencies. i happen to have a pic of this. the big chamber added before the muffler kills the low tones and the smaller chamber added before that kills the mid range frequencies. this is custom work, not an off the shelf item.


    these are my ideas for today. some may work and some may not. i hope people can try them and report how they work

    Would increasing the overall length of the exhaust help raise the pitch?

    Jim, think I recall you saying you couldn't rev it up b/4, so this solved that issue? If so how does it sound now at higher rpm?
    It would rev just fine before, ( http://www.youtube.com/watch?v=9nSojY0kDZ0 ) this is before the circuit.

    Now it sounds wicked. Talk about exotic sound on a budget.
    Engine $500.00
    Muffler $330.00
    Exhaust Pipes $220.00
