Does dual exhaust cut down in horse power? What's better on a crx SI? HKS, Apexi, or Tanabe?

Duel exuast on 4 Cyl. =

 

Quad exhausts on a 4 cyl though = (joking)

A rule of thumb I believe is that there should be one exhaust per header. Something like that, may be someone could correct me on this if its wrong.

 

Id say thats a good rule of thumb but my sisters 3KGT VR4 is a V6TT and it has 1 muffler and a resinator on the other side. Odd thing is that when I was looking for a system for it all I found was single exhausts with the exception of the Bozz Speed off-road system.
Take it for what its worth.

You dont need a dual exhaust on a honda motor not enough back pressure there to make it worth anything. And also its just more weight on your car. For all show say if you had a black widow rear then maybe it would make sense to do dual exaust outside of that its a waste of money.

 

Dual exhaust will end up hurting you. When I first got my B16a CRX (About a year ago), it had dual 4" tips on it; coming from a FloPro muffler (Made for a V8). I took it off and put on a canister, and it was MUCH better. The dual sounded like shiet too.

only thing your doing is weighing down your car.

 

The only problem with dual exhaust is the cost. Do you think Honda would put daul exhaust on of its fastest 4cyl car if it hurts performance?

 

That's a Hi-Po engine though.

 

If that's all true, no one would have a header. Exhaust would be blowing through the radiator.

ROFL,

You're comparing a S2k engine vs a CRX Si...

Lets go ahead and add the rear wheel drive to this CRX while we're puttin on the dual exhaust.

Your ignorance astounds me.

 

if you have enough exhaust coming out to merit a dual, then do it, if not don't worry about it

 

get two obx mufflers and run 2 3/4 and it helps and sounds great

 

thats not a true dual exhaust, that is a dual outlet muffler...

 

ijjz's right. there's no point to have one pipe that branches out into 2 when it gets to the back of the car. The stock S2000 might have 2, but the Spoon Sports and other Super Taikyu racing S2000s only have one. Makes you wonder.

 

What does the car being rear wheel drive have to do with it?!

I realize that the exhaust on an S2000 isn't a TRUE dual ehxaust so to speak, but it IS what he was talking about.

I do realize that there are better options on really high HP applications (race header) but I don't think you're going to lose HP with a dual exhaust.

 

Don't do it man, I'm sure the drivebility will be great around town and it'll sound good too tho

 

Its not a true dual exhaust.. most of those dual exhausts are for looks... If you added a dual exhaust were the pipe runs into a muffler that has two exits.. it wont hurt anything.. but if you took two of you headerpipes and ran that to a muffler, and the other two pipes to another muffler, that would be a DUAL exhaust system and the car would run like Toby from the Po po.

The S2000 isnt a TRUE dual exhaust. it goes from teh header, to one pipe, to a muffler with 2 exits..

whtever.. dumb thread.. just get an exhaust.. no big differences anywhere in horsepower.. just sound.. asnd looks.

 

Exactly, only thing worth getting an exhaust is so it can breathe. If you are looking for HP you might want to plop your money else where for now.
