Nice sounds crazy!!!

 

LEXUS "IS350" Intake: Exhaust Suruga Speed​​: EX Mani certain prototype manufacturer (type unequal length), straight pipes, PFS is a combination of speed loop sound muffler Suruga.

 

wasn't there a thread about this exhaust couple of years ago?

Anyway, yeah it sounds awesome, but expensive as heck. Someone please do an Ebay set up

 

holy ish! that sounds AMAZING! Deff doesnt sound like a V6

 

Did anyone ever do the eBay ballin on a budget project? That sound is exactly what I want out of my 350

 

I think I have watched all the videos in this thread like 5x

 

Which videos are you talking about? I'm considering running this setup with an invidia mid-pipe though I hear a true Dual with an X-pipe sounds better and the Suruga itself has one of those and I'd like to mimic that as closely as possible.

Anyone know of a good X mid-pipe thats comparable to an invidia in price I might be ab le to use? Furthermore anyone know A good, trustworthy shop near Tacoma Wa, where I can have those twin loops cut and re-welded?

 

Bump for info, anyone do an ebay set up? Lets figure this out.

 

Both of the sellers I contacted only had left sides, so I would have to cut and weld to make a mirrored pair (not a big deal). I am now stuck on the physics of the twin loop muffler. Has anyone had personal experience with one, or better understand the actual physics behind how it lowers the octave. I understand that a longer pipe means the frequency travels farther and stretches out, but how does that relate to length. Is there a formula? Is there an optimal length I should shoot for to get the deepest sounds without destructive interference? Any help would be appreciated.

 

You're best bet is to just mimic the setup that is shown within their videos and the couples of pics floating around the net.

To this day, I still want this guys EXACT setup...which include Suruga Speed twin-loop mufflers. Translation is "LEXUS "IS350" Intake: Exhaust Suruga Speed​​: EX prototype maker Mani certain (type unequal length), straight pipes, PFS is a combination of Suruga speed loop muffler sound." :

 

sounds amazing! someone try this so we all can haha

 

Still can't believe this thing is a V6....

 

Agreed. Is there any company in the US that makes something even remotely close to how this sounds?

 

Twin loop mufflers are more of an import design staple. Some euro muffler setup employ similar designs as well.

 

I Wonder if the car in the above video has some kind of aftermarket header setup as well as the loop mufflers. The English translation mentions unequal length and Mani (manifold?). It could explain why it sounds like no other exhaust setup for this car and why it sounds different to the other Suruga videos.
