*Anyone try Side EXit exhuasts yet? *

LITEWAITM3 · #1 (**permalink**) 06-03-2003, 10:09 PM

Has anyone experimented with side exit exhuasts?

It would be a solid day of work in the exhuast shop, but I think if you use some nice cylinder mufflers, and 2.5-3" SS it can be toned down but still sound ridiculous, and most likely have a tad of gains. For FI it would help moreso.

I think it would be pretty cool, since its already being used on a bunch of club and pro racers, It would be something to look into.

Anypone who has pics, or even better videos of such a setup either on street or some club cars, please post them.

Thanks

Yeah i wish i had an M3 GTr also dude... =) Hehehe.

Sounds like a cool idea though. I've never seen such a setup on a "street legal" BMW. If someone were to pull it off it would definately turn heads.

If you're talking about what I think your talking about the exhaust would be too close to the gas tank and sit too low. If you removed the tank, you;d have no problems. Kinda looked into it a while ago.

And this mod would be useful only for V8 and V12.

What Portal said is correct. Every and all race cars we deal with have there standard gas tanks removed, replaced by a fuel cell that is "supposedly" more fire retardent and are much lighter. It is also put into the trunk so there is no way for anything to hit it. If you did a side exit exhaust on a non-fuel cell car, you would run a HIGH risk of making the gas tank too hot, igniting it. I don't think that would be good...

The gas tank on my vw's is under the trunk area, right over the exhaust, and they have no problems in the past 15 years....I'm sure you can route it to be safe.

And GirtzB how come it would only be usefulk on a v8 or v12 ???

because of the configuration of the engine, on a V8 there are 4 cylinders on each side. so there would be a 4-1 exhaust manifold on each side of the car.

Well who said it was for both sides? Just like the Wc cars,exit out one side...

Ive seen JPPerformance done this on one of EVOSPORT's E36 race cars. Sounded awesome and looks cool too. I'll try to see if I can get pics later since the pic on the site isnt the updated one.

Side-exit works with any configuration.. BMW did this back in the day with S14 4Cyl E30 M3 race cars.

Here's the only street car i know with it, but again, it has the Fuel Cell replacing the gas tank.

He also has the other coolest mod out there.. onboard air jacks (~$4k from AP Racing)

DTM car..

Thats Alex for ya

Thanks for showing Side exit is used in many cars, even 4cyl touring cars over seas use em.

And about the quickjacks on a street car, thats just ridiculous! The $4K system is not the standard setup, the standard setup is about $2K of components, maybe $4K with custom subframe mounts for the install...needless to say it ispretty cool, useless, but cool.

Also on that car you posted, his rear "stress bar" looks like a but nmuch haha

That car doesnt look too street friendly. I see many aftermarket mods to the drivetrain and suspension in that picture. Probably a weekend track car. Isn't it the same car with the fuel cell? Those air jacks are good for the quick wheel swaps he might need. Just a thought.

Yea its definitely a sick car, but I am guessing weekend tracker, or show car since it has all those "race oriented" parts. Would be pretty handy though... but you have to either carry around or have access to a powerful aircompressor

That guys car is exactly like the one this guy owns where I live. I think it was also featured in performance BMW.
