This exhaust KILLS this car...
 

I am big into turbos, big into BMWs... and I almost like this car....

I have a few hang ups with the practicality of his build like the wastegate completely ruining your hopes of changing the s-belt in the parking lot, or the downpipe keeping you from being able to change spark plugs.... but once you get around that.... there's the exhaust...

Yuck! Ruined! I have a friend with a turbo M Coupe which was built with none of these issues on a larger turbo and has a nice nice rear end with exahust in factory spots but bigger... the crooked muffler looks hot on a supra or wrx... it ruins a BMW. Sigh :(

Thoughts?

i agree with you. any pictures of the rest of the car?

lol... with work wheels and tires like that... I think it's badass...

then I throw up

That entire car doesnt make much sense for practicality but that exhaust is plain stupid.

The car looks good except for the rear hatch spoiler thinger that a lot of m coupe guys run. Its a funky 3 piece deal that wraps around the back... but I can deal with that. The wheels are hot. The exhaust ruins it :(

Yucky

Not only does the exhaust not fit the car, it's got way too much angle going on with that dangle.

It gets worse

look at the bend needed to make that stupid angle

german cars look so much better with just straight pipes.

Who the **** thought that was even a good idea?!?

He's an idiot. Large diameter, dual straight tip is all it needs.

IMO they all look stupid crooked. To each their own.

Thats just stupid...generally cars like Z's, 240SXs, supras, etc..the reason the exhaust is crooked is because it goes over the rear crossmember, then under the axle and the angle is created by those bends. I know on a Z31 the stock exhaust runs that way, then the tips have bends to exit out straight.

You can kind of tell here when my Z31 was straight piped as a NA, I didn't put a bend back in it to bring it out straight, so it was at a SLIGHT angle, but not like that ricer angle

I think he did Euro+JDM style on that car. Exhaust or the muffler intself looks like it's HKS Carbon TI.
I agree the exhaust is angled kind too much.
But I am sure the exhaust is angled for back pressure to have a faster spool-up for larger size turbochargers @ low RPM, and I kinda like that
JDM wheels on EURO = SEX

No offense or anything, but that makes ZERO sense.

Yea but he could have just as easily ran a decent twin tip muffler or even straight pipes. In fact it woulda been easier to do that because of the stupid s bend they had to put in to get that angle. Plus, German and JDM do NOT mix, period. Unless it's in the sense of maybe like an E30 with a 2jz or something of that nature.

:lol::bigeek:

flow dynamics isn't something you're familiar with is it?

Well correct me if I am wrong.. I can't be right 100% but that's what I've heard and experienced from my past turbocharged cars with larger turbos in small displacement motors.
I also do work with many exhaust manufactures and that's I was told.

Say you put GT35 or larger turbo on 2 liter engine. You are likely to have the full boost around 4000+ rpm, and you gotta have 3" or larger exhaust pipings for the better exhaust for the turbocharged cars.
Larger exhaust piping=less response in lower RPM before the turbo actually starts to spool.
Yes you can go with straight piping but you at least give it a bend or angled out exhaust for some restrictions to the exhaust flow.
It's like you put a silencers on the exhaust and car all of sudden responses faster but of course it will loose power..
I have a toothacke for whole day and I am in pain so I can't really get it out but I hope someone picks up what I am trying to say. :)

In a word... no

So your saying adding restriction/back pressure by adding the muffler and the extra turns, helps responsiveness? Because...it totally doesn't. The free-er flowing your exhaust is, the faster your motor can push exhaust through it, therefore, spooling the turbo faster.

what does that have to do with "needing back pressure"? why would a negative force traveling against your exhaust gasses ever be beneficial?

if you were exhaling through a straw with all of your might....how would a pressure/force fighting against your exhale make it easier for you to continue trying to exhale through the straw?.....it doesn't....scavenging efficiency has to do with piping diameter at certain air velocities/temps....your exhaust pulses spool the turbine to be honest. ever wonder how a 1.3 rotary can spool a monster turbo the way they do?

Alright you got me on this, since all the cars you mention have straight pipes coming out the back, not crooked.

I think you mean aftermarket pipes come crooked

Because the stock exhausts have an extra bend in them after going under the axle, if you run it straight from the axle out instead of having that bend then they are crooked, which is what most aftermarket pipes do.

Maybe the owner is doin some mad tyte JDM drifting y0!

Honestly the car is ugly in it's very nature anyway, the exhaust ruins nothing at all. The Works were wasted, they don't work (no pun) on that BMW at all, plus the colors are off. Gay blue + gold wheels = puke.

About the only thing right on that car is the turbo and the Falken FK452s.

Big canister mufflers got played out 5 years ago. I do like angled tips but this dude went about it all wrong and The bend before the muffler is just poor design all together.

Nazi rice.

Got any reference pics so I can see these bends?

How can you own such a sick car and supposedly run a Korean sport shop think that additional bends in any piping will improve engine response? WTF?

I have always thought those cars looked like mini hearse's. The car was executed well, and I don't mind the muffler they used but the angle was a bit too intense.

lol..

I might be able to get pics of my DD Z's stock setup and how the muffler is actually mounted at a slight angle like many supras have their mufflers, but then the exit/tip has a bend to exit straight out the back...but it seems all my old pictures of the stock setup on my other car are long gone...

thats the new JDM M coupe. i like the wheels...but not on that car.and yea the exhaust????? wtf!!!! honda owner won the lottery lol
JK!!! lol
haha check out this shot in my driveway. (dont wanna jack your thread)

he washed this car i think once since hes had it. if there is a 30% chance of rain it aint even come out when it needs scheduled maintenance. makes my car junk when parked next to me :( lol

i have to see other pics of this car with other exhaust's. its not that bad. i guess if he likes it... get what you like.

I agree! I nice small sports muffler or even a smaller can slightly less angled would even be better. But the hks carbon ti muffler has to be the biggest one ever, so thumbs down. The rest of the bimmer is sexy though

A turn down muffler would be sick.

The spoiler is weak though.

Call me crazy, but I have mixed feelings about the whole car.

I'm back and forth about the wheels themselves too.

That thing needs some BBS Wheels on it and that exhaust makes that car look like a riced up BMW.

i saw this car on honda-tech and bfc before

im actually a fan of the 3 piece hatch wing, gold works on estoril, and the intake mani is beutiful.... but this would have made the car MUCH better

those style exhausts ruin every car they're on

Sounds like you need to stop talking to your friends in the shipping department.

Turbo's love sewer pipes for exhausts. The best exhaust is the biggest you can run for turbo cars.

Now in relation to spool up of large turbos, manifold design is the important thing...and there are many deciding factors involved with this. Heat retention, runner length, diameters...all play a big roll...

Free Flowing is only part of the equation. Velocity/scavenging are the most important.

I think that car, being rarer to see. Its ugly as ****. but that exhaust dont look that bad after he cut out the extra hole on the other side. but the cars really ugly so yeah.
