I don't know why people think straight pipe 1UZ sounds good, or most cars really.. xD The H-pipe really helped tone the car down a little. The crackles part of the straight pipes are nice, but otherwise it's just obnoxiously loud and doesn't sound good. Having a proper exhaust set-up or axle/cat back system always sounds better and can still be loud if you wanted it to! The only problem with exhaust systems is they're costly but much more enjoyable and don't get old as fast.
Not back pressure, exhaust scavenging. Essentially a vacuum was created where the crossover was installed. The prior pulse helps pull the next one into the collector as it exits…
QUESTION hope somebody knows. Can you make a LS 1999 have the same sound as this sc400 before the H pipe just dual straight pipes? Because they have the same 1UZ
Watched cause was wondering what my 2020 mustang Gt would potentially sound like but now won’t go true duals. No one has that anyways Ik no one will reply didn’t plan on anyone replying
I had 2.5" true duals on my 91 LS, I wanted to do an H pipe but there wasnt enough room underneath. I'm not a fan of 2.25" exhausts, it just sounds too raspy for me
Pure true duals sound good on engines like this. But I would add an x pipe or h pipe to any fuel injected vehical just to regain some scavenging. Helps with low end torque more.
@@jethermukisa9554 when a crossover (h pipe or x pipe) is properly utilized (spaced evenly) between 2 separate cylinder banks, it allows the separate pulses to cause a vacuum, essentially sucking the next exhaust pulse out. Better flow means more power.
my experience with true duals. It got old, FAST. Best for my ears is the h-pipe and chambered mufflers (on cars that let you put the mufflers in the middle like older Mustangs or Lexus LS400)
@@henrywal Because mufflers can create a beautiful sounding exhaust without being obnoxiously loud. There are many muffler brands out there to give your car a unique sound to your liking with good harmony, where an H-pipe into straight pipes out the back, or true duals is just unsynchronized, no harmony and stupid loud and sounds like crap most times. Unless you're still a 13 year old that just thinks obnoxiously loud, with no harmony is cool. I think doing a custom muffler axle back with a resonator delete is a good option for loud in hard acelleration, but quite in low RPM/idle with a nice tone all around.
My 93' LS400 is a full bolt on build..planning on ported heads and an intake manifold from 1UZTECH which is local to me but my exhaust is a 3" header back.. Custom fabbed Long Tube headers, 2 high flow cats, cat back straight pipe with an X pipe
