I saw a post on here a week or two ago and some guy, I think from Europe, had a nice crx with a sick dual exhaust. It had four tips, all bent at an angle upwards. It looked really nice. Anyone know what exhaust that is? I can't find the post.

 

^^what he said.

I bought the duraflex type-m flared body kit... the rear bumper just screams for duel exhaust... and if possible id like to do a true duel, rather than a fake split at the end.

 

i know what rex your talking about. he is converting it to rwd with a ca18det from a 180sx. i dunno what exhaust it is tho, kinda looked like a pep boys special to be honest

 

Why would you want a dual exhaust on a CRX? The only thing it will accomplish is making your car have less power. Regardless, I'm interested to see what kind of hacked up pathetic routing the piping would have to take...

All around terrible idea for all but the worst cars. CRXs everywhere should weep.

 

It's not your car, so shut up.
He wants to do it proper, and for the look. He could care less about functionality. Didn't you know that things only appeal for the aesthetics? If the iPhone didn't look so pretty, people wouldn't buy it.

I'm guessing an exhaust such as this would be custom... Cost-wise, it isn't worth it. The gains you'll receive won't be worth the end result, so, only do it if you really really want that dual exhaust. There shouldn't be a bolt-on out there, I don't think.

 

It's not my car, so shut up? How about hell no? Why would I want some clapped out POS dual tip muffler on a CRX? When a device claims to be about horsepower gains but in actuality makes no gains and looks like welded trash, then it's about as aesthetically pleasing to me as a malignant tumor such as yourself.

"If the iPhone didn't look so pretty people wouldn't buy it."

OH DEAR JESUS! DANGEROUS RETARD IN THE HOUSE! SOUND THE ALARMS!!!!


There are going to be NO GAINS. Period. Don't waste your time with dual exhaust... it will kill your low-end tq, and not make anything back up top. Plus the only pathetic way to get a dual exhaust system on a CRX would be to split it just past the rear wheels. Stupid, stupid, stupid... But, I wouldn't expect anything less in a suggestion from you.


When did this forum stop being about performance? I believe you and the other guys want to head that way ---> [points to appearance/cosmetic]

 

So you want to run 2 cylinders out to the back on one pipe and the other 2 to the back on another pipe? I suppose you could do that... and be prepared for the power loss as stated before. You will have less than adequate back pressure and scavenging will not occur. V-8 guy don't even run this way anymore. They pull the pipes together somewhere under the vehicle to do a X-pipe like this


Your front wheel drive car does not have any accommodations under it for space to make such a X-pipe.

I feel your best bet would be something like this


That's from a Lancer Evo.

 

I heard that a dual exhaust gives you at least double the horsepower of a single exhaust, so that would be at least 40 extra horses....Lol I'm just kidding. I just wanted to know if anyone knew what company made it, I've never seen one before on a rex. I'm sticking with my sleeper exhaust to keep the popo off my back. That megan exhaust is sick for the EVO.

 

I was actually thinking along the lines of running two smaller pipes in the same pattern of the stock exhaust. I realize it means a custom fabricated exhaust, but hey thats what makes it fun!

 

had it on a Civic of mine about 10 years ago. aesthetically speaking, looked great. i didn't care about losing power since it was an STD anyway. but va beach laws prohibited modified exhausts, so it didn't stay on long.



for some reason people just can't get in their head that someone wants to modify their car for their own personal satisfaction and not to please the masses

 

Ok, but why?
What is the absolute purpose?
Regardless of the size of pipe that you use, you still want to pull it together somewhere like an X-pipe. However, if you honestly think about what is going on here, you might as well just join to pipes together and go for one larger tube.
I guess (if you had a nice boosted setup with big displacement) you could benefit with sort of a long tube header design that goes with two separate tubes as you are thinking. Then join those two together into one larger pipe where you start the tunnel under the car. If you so desire, get a muffler like the one I pictured above and get your aesthetic exhaust tips.
Think... why isn't a Lancer EVO, which requires better flow than a Honda, using prehistoric dual exhaust? Or why don't the muscle car V-8's use ancient individual bank dual exhaust anymore?

 

Because it's his car and he wants it on there.
Okay MR. Veteran. Okay?
He never said he wanted it for gains.
He wants it to match his rear bumper.
You're just coming off as a jackass, on the internet of all places.
Your cyber-credibility is now all gone...
You've got no reason to live now...
Might as well just crawl back under your blanket and remember your youth, the good days, when you had a soul... when it mattered what you did, instead of just growing up to be an old grouchy man, living on his own, wishing he had kids or a wife that loves him. Your parents are gone now too, aren't they? That's the last of the unconditional love you'll ever feel... What? You're adopted? Well, nobody loves you, hence being put up for adoption... Whatever your background, it's just rude to insult someone's plans for no reason at all.
He wants to be a ricer, let him be a ricer.
You were one at some point too.
Also, Honda-Tech is no longer about Tech. You'd have to find the Tekh site for that.
It's about seeing who can make the biggest fool out of the biggest fool. I definitely hit a sweet spot with you though, getting you oh so angry... Mr.Lonely is mad, sitting behind his monitor...

There's someone that helped in this thread, giving a good logical explanation of things. It wasn't you, it wasn't me. Try actually contributing sometime instead of just flaming.

 

there is a lot of good info on this site, but its hard to find through all the flaming that goes on here..... how about if someone starts a thread, you answer whatever question is asked, or give a link to the info needed, then go outside and yell at the wall instead of wasting space on the server telling him how stupid his idea is?
as for anyone who thinks backpressure is necessary, or 'scavenging' etc. please copy/paste this into your browser and scroll down to myth #5 http://autospeed.com/cms/A_111396/article.html
this is a fantastic site for DIY and cheap mods.

 

Read it, but that's just some guy posting his experiences without a single dyno chart or any rhyme or reason to his 'mythbuster' .. ahem.. "facts".
And his example for suggesting shoving a potato in an exhaust isn't even fair as that creates a blockage. Blockage isn't something anyone would want to do.

I do agree that EXCESSIVE back pressure is bad - heck, I would even agree that back pressure is bad period - but with a stock engine I have to stick to my guns saying appropriate is necessary.
Savaging is a real thing. Unless the cam is tuned for the correct overlap and you have a tuned exhaust (or run open header) to support zero back pressure the engine can get some help from the velocity of the previous exhaust pulses to help pull the burnt charge from the cylinder.

Try this article on for size. If you aren't happy with it, then write their editors and tell them how Julian Edgar from autospeed.com debunked this 'myth'. Please copy and paste their reply to you so I can have a good laugh. K?THXBI!

Hey I finally found the same exhaust I was looking for that the French guy had. http://cgi.ebay.com/ebaymotors/EXHAU...Q5fAccessories
A little pricey imo, but hey it looks cool lol.

 

Ohhh, eBay. That's where you find it.

 

Lol, ebay is where its at!

 

... for a Del Sol

 

Lol, I know. It would fit though. And just so everyone knows I am not buying this nor thinking of installing anything similar. I was just curious as to where that guy had got his, I had never seen it before and thought it was unique.

 

Back in the late 80's I did a dual setup on my crx... I used a 2 1/4" piping from the cat all the way back to a muffler that was meant for a camaro (1 in 2 out) I didnt lose any power as someone on here said. In fact that car ran 14.2 all day long. Back then that was pretty quick...

I think those of you that want to hate need to go somewhere else. But then again. Misery loves company.

 

I was actually going to suggest the camaro exhaust too as I had a friend who did the same thing. It worked well.

 

Pacesetter made an exhaust for the Rex that had dual, dual tips. I had one on my 86 Si. Of course, that was a long time ago.

 

What year range camaro?

 

Dont remember the part number. Its been 20 years since I did it. But a Mid to late 80's IROC/Z28 muffler was used.

Shortly after I did that , Ron Bergenholtz bought a dual axle back piece for a Miata. He used it on his Integra. It seemed to work well also

 

Oh sweet lord.
