Bumble-Bee Hondas
I've read veil_side_'s post about loud imports and agree. I hate hearing bumble-bee Hondas whiz by me with their primered body kits *shudders*. Anyway, I'm looking to get a 240sx very soon and the first thing I'd do is intake to exhaust (header to muffler). How bad would it be if I left the stock muffler until I could find one that I liked? Thanks in advance.

An exhaust will give you little to no gains. By little I mean maybe .001%. Its all for looks/sound unless you have some sort of "power adder" on the motor that will require a higher flowing exhaust.

ktom - you say you're getting an exhaust from the headers all the way back......but then you say you're gonna leave the muffler, i don't get it.
![]() riot - you're 100% wrong. an exhaust will create more power without any other modifications. somewhat significant power as well. |

But on a serious note...I've never seen ANY DYNOs that have proven over maybe a few phonies on way top end. I would NOT consider that "somewhat significant power"...but then again your idea of significant power could be 2hp...in which you may be correct. -ryan |

headers and exhaust do make a difference. yeah you can use the headers w/o the exhaust as well. dont worry. i have a nice RS*R catback. made 136.9 RWHP w/ it on a stock KA24DE. not bad i think for being my only 'power' mod. |

![]() if you've never seen any dyno's that show power, then you either haven't seen very many dyno graphs, were looking at dyno sheets of junk exhaust systems, or just don't know what the hell you're talking about. some people claim 15whp from certain systems, i think that's a bit of a stretch, others claim 5whp, i think that may be a bit conservative. figure an 8whp gain over stock comes out to a 8/130 = 6% gain. not bad. and that could be a bit conservative. i could come up with many more arguments for you, but you're not worth my time. |

Very sorry for starting a flame war, that wasnt what this post was meant to be. I'm just very eager to get my car, because it should be happening within a week or so. And about hating hondas, that's definately not true. I just see more "pimped out" riced up hondas than I do any other sport compact. Thanks for the replies.

for any mod, the dyno chart shows the the power graph..
in some areas IE 4500RPM-6000RPM a mod might add 10HP and then when it reachs 6500 it drops off adding 1 HP they take the largest jump no matter where the gain is and claim that gain . also make exhaust companys use turbo model cars to do dynos which shows greater gains. if engine has 200 HP a 10 HP gain is 5% if your engine has 140 HP a 6-7 HP gain is [ oh... 5 %!! ] |

I must disagree with you, Ryan. A good-flowing catback exhaust is one of the single greatest power-adders to an NA 240sx.
The stock intake system is okay, and the stock header is okay, but the stock exhaust is very restrictive. This has been proven many times over. -Kevin Quote:

Teg and ktom are right; it's the people, not the company. Honda produces good cars. Some morons have fun ruining them with wings the size of Wisconsin and purple LED windshield squirters, and it's a damn shame that "Honda" is identified with "rice" due to those people. If you say "Honda racecar," though, I'll think of the F1 cars that have won three straight manufacturer's championships. This company knows how to build fast cars.
Please don't generalize about Honda owners. You guys are smarter than that. Brand loyalty is a waste of time. Civics are light, often with double-wishbones all around, and will accept a huge array of inexpensive engine swaps. Even the almighty SR20 can't match the B-series for the selection of aftermarket performance parts. You do the math- a fast car for a little green is what we're all after and a well-built Honda can run with anything out there. If this was just about having the fastest car at any cost, we'd all live in boxes and drive GT-R's. You can go fast with "Civic" on your trunk just as easily as you can with "240." It just takes smart modifications and dedication to building a great car.

Oh yeah, and exhausts work. I've got an A'PEXi WS on my Civic and you can feel the improvement, even on an NA 100-hp motor. If you think exhausts don't make a difference, try running a turbo car on a nonturbo exhaust. You'll feel the difference in turbo lag and in overall power.

what about a custom 3'' exhaust on a turbo car? straight pipes... my friend has one on his mk3 supra... he got all his parts from jcwhitney... i think it sounds like his car has bad gas... like it farts too much kinda bad gas... should i expect this out of a straight piping custom exhaust on a turbo 4? im debating weather i should go through with it... i though i could cut corners on the exhaust.. but im having second thoughts... haha i guess what im getting at is does the exhaust matter on a turbo 4 cyl as long as its 3'' piping? will i feel a gain in power or lose depending on company and what not?
sorry if thats a dumb question.. im still trying to learn... ![]() |

The name on the exhaust doesn't matter so much as how it's built. Mandrel bends, and as few of them as possible, are the main things to making a good exhaust (n/a can have a lot more to them, but you asked about turbo). As far as the sound goes, you can cut back on it a bit with a decent muffler and by packing around the pipes with fiberglass (like you see on your factory exhaust).

WOW!.... you didnt just say that.... Hondas are NOT sports cars. A CRX is a commuter car, not a dragster. I dont know who the A$$ clown was who decided a honda was a race car but its not. Ill make an exemption for the s2000 but thats it. And if anyone calls me a honda hater, good. I hated hondas before I even knew this web site exisited and Ill hate them even after its gone. oh ya,... exhasts add horsepower, not much but enough. I feel this is mostly because of the age of the stock exhast however and not the all powerful greddy gods. Id say 5hp is about right. |

Yea. Technically my Turbo S14 isn't a sports car either. It was originally sold as a "Luxury Sports Sedan."
Anyway... exhausts are part of the entire engine's ability to breathe. It'll only be enhanced by either an intake or a cone filter on a turbo. They're not overrated, and a necessary upgrade to any path of modifying (NA, and FI). Just my thoughts on this. I'm not a 240sx guy. I'm a car guy, and I'd have one, if there weren't so many damn 10-11 second Civics around. Performance is beauty, and I don't care if a Viper or a Civic or even a Mini Cooper beats me, I'll have respect for *THAT* car. $.02 <-- -Jeff

my set Idea of a sports car is a viper, skyline, cobra (shelby), Supra, Corvette, gt 40, 300zx TT, 350z. That type of car is what I would think of when I think of a sports car. I just cant look at a honda and see a sports car, I know 240s arent sports carseither but they get close to it. There are alot of hondas out there that can move pretty quick but thats on a strip, Ive never really seen one do well on a track.

Hey Raptor, BTW, your name sounds pretty fearsome, I'm scared of you already. That's the kind of name somebody makes up in seventh grade because they think it sounds cool, and by the time they hit college they've realized it's stupid. I guess you never got there though. I have no patience for people like you. Call me an "A$$ clown" if you want, but your attitude is just pathetic.

I didnt call you specifically a clown. But looking at your info, I would. You say yourself, "Im a civic poser". Im sorry mister Spoon, I must have confused you when I said what I did. Ill stop using such big words, like and or that. You are exactly the type of person that I see around here all too often, and yet another reason I detest hondas. |

Personally, I think you guys are idiots
![]() "I just see more "pimped out" riced up hondas than I do any other sport compact." Wow, look at that, he actually said sport compact which is exactly what civics and 240sx's are...isn't it weird how you flipped out about how hondas are NOT sports cars for no reason? "Ive never really seen one do well on a track" How many times have you been to the track? "I dont know who the A$$ clown was who decided a honda was a race car but its not.

Can we cut the crap about hondas? I mean really, I thought this forum was meant for nissans and infinitys. If you really think about it, honda's are for low budget racers, PERIOD. If you think about it, everytime consumers buy a product, later on the price goes down eventually. Look at honda parts compared to nissan's. They got weapon r, mugen, spoon sports...etc. etc. And we have other's but not many US company's pay attention to us. So, really if there were really any real tuners out there, they'd pay attention. You can't compare a stock all-motor civic to a nissan turbo. Stop your guys' whining because if you're in this forum, if better be a good reason, especially about what car you drive.

ever wonder why half the people in this nissan 240sx forum drive hondas? hmm, i might be able to find more stuff about a 240sx on the honda forums.........no offense to the honda guys but dont you have your own forum? well maybe you got few cars? but i like the nsx its pretty sweet
and as for exhaust you can make or break the car with it......to small too much torque not as much horse power, and too big too much horse power and no torque..... my friend had 3 in on a na civic and it sucked, then he tried a 1 1/2 straight pipe to the back and it was kinda wierd with the torque, but he eventally went back to stock Last edited by ryan hagen; 02-17-2003 at 03:05 PM.. |
