i know this really dosent pertain to the tC but ive wondered why most drift cars have angled exhausts. i have the ZPI exhaust myself and its sort of angled as well. i personally like the look of angled pipes but is there a reason why they are like this??

 

poor taste? :p

 

JDM Tyte

 

There is a "performance explanation" to this. Instead of going into this big technical write-up, I'll just copy and paste a description from HKS website:

IRONICALLY....most people don't know this, and just do it to try and look cool.


EXAMPLE

More Restricted





Less Restricted

 

I think the trend just caught on after they saw what all the VIP cars were doing...

 

except on a tc it is useless

 

compared to the stock design, how is it useless to put a straight pipe out, then the muffler?

 

I didnt say that running straigt pipe and exhaust was useless, but to get that "JDM" looking angle on our car you actually have to put more bend in the pipe.. at least from everyone I have seen. You could run the pipe much straighter without trying for that angled look. The angled look came from cars with the exhaust closer to the center of the car. The angled tip got rid of the need for an extra "s" at the end of the piping. On the tC they are adding more bends just to get that severe angle on the tip

 

I disagree. My exhaust is pretty straight. Not to mention that the JDM lean exhaust really only differ from a Straigh exit exhaust at the Rear Axle Section of the exhaust. They are pretty much the same up until that point. It's that last section that hinders the flow of gases.


You did look at the post I made previously right. How can you say that the top pic has less bends

 

I dont see how it makes more bends, the only option is to have the muffler to make that severe angle.

 

^^Thanks Zero. It's not the pipe that bends, it's the Angle of the muffler that does. Therefore, the Pipe is straighter and flows more....HENCE the JDM LEAN!

Albeit, the ZPI Exhaust is a cross breed between JDM and a Straight Exhaust. But still flows more than the traditional Straight exhaust setup.

 

the only way a straight exit would be less restricted than the angled version is if it exited out the center of the rear bumper.

if you look closely you have to move around the right rear lower control arm. so you only have one bend (around the control arm) and exit compared to the bend around the control arm and then another to straighten it out.

 

Want to know why drift car's have JDM lean? It's because more than likely they are running boost, and if you got enough money to run boost, and burn tires in an hour all day, then you can make your exhuast the straightest path, and have the JDM lean, you earned it.

 

angled exhausts first were used on race cars in the Taiku N1 endurance race series in Japan during the early 1990's (later renamed Super Taiku). This is long before drifting became a professional motorsport in Japan. Japanese companies like 5zigen, HKS, and Apex came out with long cylinder style mufflers that could be angled to restrict bends in exhaust piping (what someone wrote above in a previous post). The rest of the world was still manufacturing oval multi-chambered mufflers (like traditional Borlas, Walkers/Dynomax, and Flowmasters). In the last 10 years (as japanase tuning gained popularity), other non-japanese companies began making mufflers similar to HKS, 5zigen, and Apex's original designs.

I argue Apex was the first company to market the round-cylinder muffler and the "JDM lean" look during the mid-1990's with their N1 exhaust (which is named after the race series they developed it in).

The "lean" was put it in so the muffler could still exit out the rear bumper cut-out. These mufflers traditionally dont have extended exhaust tips, so you have to mount the muffler further back to meet the bumper cut-out. In that regard, you have to angle it up or it'll scrape on driveways.

The ZPI muffler doesnt have a true "JDM lean" to it since it uses a separate pipe to angle the tip.


True "JDM lean" mufflers have the tip on the canister (or virtually no tip at all), requiring the muffler be pushed back. If not, it will burn the bumper.
Apex's N1

HKS' Hi-Power

Tanabe's Racing Medallion

5Zigen's Miracle (although the Border exhaust was the original)

 

Looks like I may stand corrected I had it in mind that there was a straighter path out of the car than having any bends back there, but after looking at mine, the control arm would make this too low to the ground.

 

still looks pretty dumb on tC's.

I highly doubt you'd see a difference between PURE JDM SLANT! or just the normal straight exit. Unless you have a fully built motor pushing 15psi.

 

i think these angled N1 styled mufflers are played out. So 1990's. LOL.

i always loved the Dual N1 from Apex. Unfortunately they only make it for 240SX and RX7.

 

oh my....

 

everyone is entiled to their opinoin. personally I love the slant look and according to most people I am a trendy homo because I like the whole jdm style. even though the tc was only marketed in america. I have no Idea if it is sold in japan yet.

I think the angled tip makes it look more agressive and more for a purpose than than the straight exit, especially with the burnt titinum tip, even though that looks sick too and was a jdm trend before it hit american streets.

I guess it all depends on preference.

 

I do like 1 angled exhaust on the tC, it's an Apex'i N1, not as drastic as the HKS.
