I'm thinking of getting Racing Straight Pipe. What do u guys think??
Waht do you guys think of Straight Pipe??
|
Like a big Dodge one??:confused:

WTF? Some of you need to do some reading...
First, removing the cat on a CALI emissions will NOT trigger a MIL, but might on a FED emissions since the FED has a 02 sensor after the main cat.
Second, removing the main cat and replacing it with a straight pipe will NOT "smell". Only if a cat fails does it smell like rotten eggs unless you mean as in crappy emissions smell. IF so, then you need to become a wine sniffer or something.;) 3rd, there are minimal if any gains thus NO point in removing the CAT unless you've already done a catback and Y-pipe and even then it's minimal unless you have FI. 4th, the sound increase is minimal UNLESS you have a Y-pipe and catback. 5th, the MAIN reason to run a "straight pipe" is to prevent ruining the cat by running N20/SC/Turbo or for a good EGT or A/F-sensor mounting point. Actually, it's probably better to mount those closer to the engine, but this is a convienent spot. There are more, but those are just a few off the top of my head. |

I put a test pipe on and it was REALLY friggin loud. And I have a Y pipe and catback. |

Re: Re: WTF? Some of you need to do some reading...
Take it from someone who has a race pipe.... I do not relay second-hand information.
1. No smell but definately a "hotter", more humid exhaust. 2. It WILL improve performance and the difference is noticable I repeat..This mod works. Could chirp in third easily with the race pipe. Without it...no more. 3. It is definately louder. IMO it is the best "bang for the buck" mod out there (30 bones) -Left |

just do it!:)

mmm...my friend with a S40 just replaced the cat with a straight pipe, now the car smells like ****. There was absolutly no smell of any kind before he did this. What might be causing it?

Sorry, but I don't know S40s exhaust design...
Originally posted by CharlieNewbieMax mmm...my friend with a S40 just replaced the cat with a straight pipe, now the car smells like ****. There was absolutly no smell of any kind before he did this. What might be causing it? IF he's positive the two are related, I'd replace the main cat ASAP and go to the dealer. It could cause engine damage, but I'm betting the ECU would have triggered a check engine light first. Just a guess though.:confused: |

Originally posted by IceY2K1 I wasn't necessarily directing that at you, since I said UNLESS you have other exhaust work. Yes a straight pipe installation would probably be more noticable with a cat back/y-pipe, but the high efficiency of the 2K2 exhaust probably makes this a moot point. I cannot speak for earlier Maxima models, but I imagine the cat is not predominant bottleneck in the exhaust system. We remove precats to get less restriction. Why would a cat be any different? -Sensitive Butt |
Sensitive Butt Dyno Man.....hehe
Originally posted by LeftCoast Understand your point, but I have to once again disagree. Removing the cat from ANY exhaust system will increase exhaust air flow. It does not make a difference what Mods you have installed. Decrease restriction = increase performance.

I cannot speak for earlier Maxima models, but I imagine the cat is not predominant bottleneck in the exhaust system. We remove precats to get less restriction. Why would a cat be any different? -Sensitive Butt In the other situation(already have a Y-pipe/catback) you are correct that the cat is a bottle neck, hence restriction. |
Re: Sensitive Butt Dyno Man.....hehe
Originally posted by IceY2K1 It's all dependent on exhaust gas velocity. The whole idea is to speed up the exhaust by removing any restriction(to a point, since some backpressure is good), however when you have a punny little 1-5/8" or whatever exhaust and you drop in a 2-1/2" cat/straight pipe you create a "pocket" or expansion area. This pocket doesn't promote exhaust velocity, instead it causes turbulance, which is a restriction. The going from small Y-pipe---to--2-1/5" cat or straight pipe--to--small catback is creating a turbulance in the column of air flowing out the exhaust, ie decreases the exhaust gas velocity. In the other situation(already have a Y-pipe/catback) you are correct that the cat is a bottle neck, hence restriction. |
Re: Re: Sensitive Butt Dyno Man.....hehe
Originally posted by LeftCoast OK, I'll buy that. I suppose the question remains of which is the lesser of two evils. Turbulance or restriction... I suppose we'll never know until someone actually does a dyno. Maybe I'll try to calibrate my sensitive butt while I'm there... :D |
You left yourself open for this....
STOP LOOKING AT MY AZZ YOU DAMN YANKEE FAN!!! |
I dunno if I believe it but custommaxima dynoed theirs and got 11 hp?

ok...i dont know what u guys are talking about, when i had my car striaght piped, not cat back, or any crap, my 2k2 felt pretty damn good to me, the sound from the car was just as loud as my friend w/ his WS6 w/ loudmouth, im sure kloogy knows what that sounds like, the sound was close but the max was a bit more raspy. THAT SUCKER IS LOUD~!! minimal difference, ha... the power and sound i got was well, lets just say "GROAN GRABBINGLY SPACTACULAR~!!!" the only thing is, i was traveling around 14-15 miles a galon so i decided to put it back on....U GUYS SHOULDN't act as though u KNOW until u've accually tried it. im not trying to start a fight, im just voicing my opinion

oh dude, i didn't see what kloog posted til now...hahahaha, where do you find a smilee like that???????

Originally posted by doublea Hey Woo Cho, check on http://www.custommaxima.com/RacingPipe.htm, I saw they have a nice SS test pipe that replace the main cats, I think they dyno'd + 11HP, plus it have a build in resonator. I will be buying one soon. Che Che AA ;) here we go again.. show me a dyno with this installed giving you a 11 hp gain... (i have one i know it does not) and the price it too high anyway.. :rolleyes: |

(i have one i know it does not) and the price it too high anyway.. :rolleyes: Hey redmaxpa007, here is the link to custommaxima website link for the dyno sheet, if the link doesn't work, just copy and paste the adress in your browser. http://www.custommaxima.com/RacingPipeDyno.htm (i have one i know it does not) and the price it too high anyway.. There might be many reasons why you didn't achieve equivalent result, to name a few, what year max you have ? Do you have, Y-Pipe, Intake, Catback, pullies etc... does your max is auto or stick, Numbers will vary from one application to the other depending on the car itself and the mods already in place. All theses factors will have an impact on your final numbers, there is no magic in car modding, think of it like an escalade of things, As for the price, 99$ for 11HP, that sound like as weat deal, a Y-pipe cost like 350-450$ and give around 12-16hp. I will certainly give it a try soon. Cheers AA |

Re: Re: Re: Re: Re: I'm thinking of getting Racing Straight Pipe. What do u guys think??
then you will be wasting at least 50 dollars.. cause i got one for $67 shipped more power to ya...:rolleyes: e-mail me and i wil tell you where to get one cheaper. 11hp.. hehehe Not sure what why all the animosity towards straight pipes. They work...Its proven. Are you simply standing by your original position just for the sake of arguing? If that's the case, then I'm here lead you toward light. Bring it... |

Bring it... i am only saying i can save people money.. and straight pipes will give you a gain, yes, BUT not 11hp (supercharged with NOS maybe on a good day) |
