Is it possible to make a traditional pushrod LS3 sound like a flatplane V8 by simply changing the exhaust? On today's episode Zac puts this theory to the test and compares two VERY different exhaust designs for the C6 Corvette. The results were shocking to say the least.

It’s like 80% flat plane sound, with 20% yank v8 bass rumble underneath it. Sounds sick!

I drive a 2011 C6 Z16 LS3 6 speed manual with the GM performance exhaust (which I have added a switch to). I have never heard a Vette sound more like a Ferrari than the Celeritech, but for me it's the American V8 rumble that I love and will keep.

So i had an idea for an exhaust to hopefully make a higher pitched sound, youd need to pinch the tubing and place a blade of some kind between them. Similar to putting a piece of grass between your thumbs and blowing to make a whistle

with how unique the celeritec system sounds it puts it leagues ahead imo

[@NXT_LVL]

I’d personally go the throaty route BUT have the Celeritech 8-4-1 setup for sure. The difference in sound also has to do with the substrate density. As Borla says, “it’s like tuning a pipe organ.” Now that you have the bones of the exhaust system you can swap mufflers to tune the tone deeper, mellower or just run cut outs. So it’s a Jekyll and Hyde setup

[@redlion145]

I've always known mismatched builds as Frankenstein setups. Jekyll and Hyde sounds like you've got exhaust baffles for flip-switch loud and quiet.

Tuned for a deeper tone if they can keep the drone to a minimum 🫡.

As for drone... everything drones, just depends on how much dynomat you have and what setup you have. All 4-8 DOD systems drone. Straight pipes on a daily isn't realistic either. The Spintech 6000 I have on my truck only drones at 25-30mph at like 1200-1400 rpm... at 1900 at 70mph its a mellow tone and you can still have a decnet converstion at normal volume... and it's side exit.

[@juangil5625]

first video recommended by this channel . Pretty awesome video. However, why did they just explain that the difference is equal length vs un equal length headers. The burble American sound is from the unequal length. Its similar to why a flat 4 or a flat 6 has that same burble.

[@fiddynutz68]

​@@juangil5625those were equal length long tubes.

[@Slysdexia2]

​@@juangil5625 The American V8 burble is because cross plane V8s are odd fire, not even fire like a flat plane Ferrari or the new Z06. Cross plane v8s run in a pattern that always has two cylinders fire concurrently on each bank at some point (which even fire never does). This creates an audible effect similar to an unequal length header, but via a very different mechanism. In general, V engine headers are rarely *perfectly* equal length, as the front cylinders are further from the back of the car, but that's a small effect versus the cross plane engine configuration. Celeritech emphasizes equal length to specify that each runner has an identical length which does help scavenging when you're going as far into it as they are. Their specific sound comes from pairing the cylinders together to avoid the clash of exhaust pulses that help create the burble.

[@dons1932]

​@@Slysdexia2 What are you even talking about? You can build equal length headers with paired cylinders for any V8 engine, regardless of whether it has a cross-plane or flat-plane crank. The wailing sound comes from joining both BANKS of the engine together, usually with an X pipe, but they have essentially created that via a merge collector making one giant long X that joins the banks into a single pipe, then spreads out again. The closer the merge of both banks to the engine, the higher the pitch. That is THE ONLY reason that exhaust sounds different, with the one that has the X pipe way further back. A flat-plane crank engine only sounds different because it is essentially like having two 4-cylinder engines bolted together.

[@Slysdexia2]

@@dons1932 If you can't hear the difference between a cross plane V8 using an X pipe and a flat plane V8, I don't even know where to start. Yes a merge between banks changes sound on a cross plane V8, and quality X pipes at the correct merge angle can produce a noticeably higher pitch, but this does not change the fundamental odd-fire behavior of a cross plane V8.

[@adamarndt7617]

That's the most beautiful, professionally designed exhaust system end-to-end I've probably ever seen (Celeritech). All the Calvin Elston high-speed exhaust magic. I wish they made one for C3 Corvettes. (They'd possibly sell 2 or 3; lol!) I vote to keep the Celeritech, but maybe get mufflers put on it to reduce the total sound output... It's WAY more unique and that high velocity and mid-range torque with increased cam overlap is just FUN! The torque you can use every day.

[@Ky_Mycology]

I've gotta say the Celeritec for the win! That thing sounded nasty with that full Titanium setup, plus the low and midrange power gains are not to be ignored!!!!

[@MrFindoutman]

Mannn, I’ve been wanting to do a higher pitch, more exotic sounding exhaust for my truck (especially since everyone’s sounds more or less the same) and it’s a for sure thing now after this video! I guess no one other than these guys can make a equal length, 4-2-1 header tho huh?!

[@adamarndt7617]

There's usually SOMEONE making 4:2:1 headers for trucks, because they tend to help with that low and mid-range torque and MPG. Then you just need to merge the pipes from each bank into a single exit to get that sound. It's also easier to physically make a 4:2:1 header for a lower RPM application like a truck, as the tube lengths need to get shorter and shorter as your target RPM goes up, so they get harder and harder to physically fabricate.

[@john.f.remedy.237]

The celeritec is my choice. Sounds real crisp and sings in the higher rpm’s and it’s unique…

[@jakegardner3181]

I have a pontiac g8 with a ls9 and if I could get the celeritech,I would. It doesn't sound that great at free Rev, I agree, but it is such a unique sound under load, I like it. I like unique though. If you can stand out from the crowd, I like it, and that system does that.

I agree, I absolutely love the traditional sound, but every one and their mother has it, also the haters are probably too broke too afford it anyways.
