Will it make any difference?
I think it'll just add more weight and be all slow

 

A full catback is not needed on an N/A car. Most people get them for the looks/sound, the HP gains are VERY minimal if any.

 

Change the exhast... If you like to hear the roar of the engine... I do. An I like to set off alarms

 

yo sexima when are you gonna update your homeP?
hurry hurry... <--- Red Devil... OH~~ KOREA OH~~ KOREA
dang this worldcup turned out really good eh~ did you have fun watching em games?

 

Sexima you'll probably gain 5hp and 10db with a cat-back so it's up to you. But if you want more power and already have intake/y-pipe it's probably the next step.

I"m thinking whether I need a catback too.. My stock exhaust started making a weird noise, which means there is a hole somewhere...

I wonder if a catback will help a lot for NOS'ed people.

 

Its not all about HP, its just to open up the air way so your car can breath a little, most maximas chock a lot around 80... getting a cat back will help your car breath and pull harder as it gets higher in MPH...and plus your probably not getting the full HP out of your Y pipe because its letting a high air flow threw from your engine, but is trying to squeeze it out your stock cat back, witch is just creating back presur, and can atucly be slowing you down

yea, when they installed my y-pipe, they said there was a leakage somewhere down there, there was some water coming out of muffler instead of all gas...recommended me change my catback but wouldn't kill my car so i said the hell wit that

 

Jesus, never go back to that shop. I guess it never occured to them that a by-product from a catalytic converter is H20

You'll shed about 10-15lb in weight with a catback.


Dave

 

hot damn... who's that model in your sig sexima?!

 

lol, so it IS common for water to come out of muffler....

 

yea that korean game was hot
haha I'll update the page!
The babes section haha ok?
I got new pics of my car.. it's 5am right now and im tired
hmm..
does full catback and just muffler sound different?

 

Just added my Apexi WS 3 days ago. Its loud, and i haven't felt any real hp gains but i can tell you that i have lost torque. I will tell you that 5-10 hp gain is BS! but the Apexi ws sure does look nice on the max.

 

has anyone experienced this problem with a greddy cat back??

 

There is a piece of the b-pipe that is crushed down to 1/2 the diameter it should be....It's sickening why nissan would do this. One rule to apply when upgrading your exhaust is: "Your exhaust is only as good as it's smallest part." Yea it's nicely opened up at the downpipe section, but you still have to cram all that air through that crushed section. It ain't gonna flow any faster and it'll create backpressure. I put an apex'i catback and the difference is night and day. I think that the gain felt just as big as the addition of the y-pipe. Gave me top end power I didn't have b4. Do not hesitate to get a cat-back...It's well worth it. If you're on a tight budget, get the B-pipe.

 

you will still run fast times with just a ypipe. if you're like me, i pieced my entire exhaust. i have the courtesy bpipe which is fine, but you might want to try the new warpspeed SS model when it comes out. or the stealin one because sometimes my pipe bangs when i hit a really hard bump. the rear axle comes up and meets it slightly. also, have a muffler shop weld you your universal (i highly recommend borla turbo/proXS). if you feel like being a test mule, try one made for an suv. my theory is it will be quieter on our cars since it was made for a larger engine/load. you can always go back to the stock rear section provided you keep the stock rear section. see what i mean? best of both worlds.

 

You really felt a difference with Apexi WS???????
Does it help out on high speeds? (above 80mph)

I used to have a custom catback, but I took it off because that thing was too loud.. I want to get a bpipe now..

Please post your detailed before/after analays of the WS..
Oh man, I sound like a newbie, sounding like a catback is gonna give me 25 HP. haha. But I am very disappointed with my off the bottle times. I need to do every little thing that helps.

 

Yes, the Cat back is going to help your car have more top end... If its to noisy for your taste, they get piping with a resonator that will muffle some of the sound. I can tell you off hand it helps because when i was stock, with just a pop charger, my friend had an Olds Alero 99' and 0-60 i would kill him, so i was like ahhh yep my car is sooo much faster, i would even sit right next to my friend with a 96 Impala SS... once on the high way, i raced my friend with the alero and the impala and from 75 + and the impala killed us, and my friend with the alero sat right on my *** i couldn't shake him, i was confused I thought if u can beat a car 0-60 you can beat him from any mph no matter what, i dident know about low end power, top end power....well finely i got a cat back with 2.5 inch custom piping, and a straight threw HKS muffler... I raced my friend with the alero from 75+ again to test it out.... This time he jumped me, i wasent even ready, and he had a car on me, and from last time i dident think i could catch up but not only did my car pass him, i keeped pulling and pulling and pulling, i was so happy...at the time i thought it was the best $130 I spent into my car.

Im sorry that was long but really, if your into speed, and what every little bit out of your car...I would recommend it, to anyone

-ChRi§

 

Do you have a y-pipe though?

 

So the $130 was for the 2.5" catback piping and HKS Muffler? Where? I'm on the tightest of budgets (college starts monday...damn books!).

 

Yeah I paid $130 because I was a smart shoper

I asked around, and my friends told me the best place to go around here (Jacksonville, FL) is to Rainbow Muffler...they said they do good work and have good prices, look around there a chain so im sure there in your area.... I bought my muffler on my own so I can save money, I went to ebay and typed in performance muffler, and read all of them and found one that was HKS style, stainless steal, and was chromed out nice and shinny...it was $50 I bid, and won it for $50.. I went to rainbow muffler and gave them my muffler and asked them to hook me up with 2.5 inch piping all the way to the cat, they did for $80 so all together i got a nice cat back system for 130 im very happy with it, if yall want you can e-mail me i have PIC of my muffler, and of my cat back on the car i can send yall if you want..

Come on guys, how can you not suggest a Cat-back exhaust system. You will gain power! As far as loosing torque I doubt it. If you do loose anything at the low end due to loosing some back preassure it will be minimal, but the high end hp and torque gain will make up for it. Normally you will gain at least 5-10 horses depending on what you have done. Remeber the horse power that will be gained is a percentage. The more you have done the more each part will give you. Say you add an intake to your stock max. The intake might give you 5 horses. If you throw in a y-pipe. Your intake might produce 7? The y-pipe alone might give you 15 horses, but if you have an intake you might gain 20 from the Y-pipe instead of 15. Capiche?

 

I did the same thing expect the idiots cut off my muffler's flange and weld it to their non-maderl bent pipe! Egads....

 

Did i feel a difference?: top end- yes. Keeps pulling past like 5500 instead of dying off

Used to have a Custom catback? a catback is just a b-pipe and a muffler. Try to get a mandrel bent one. Why did you get rid of it? If it's too loud get a quieter muffler....try dynomax, i hear they're really quiet.

 

No offense but I think you all are smoking dope. I just put my Apexi WS on and gained about 1-2 HP at most and lost torque. The cat back was absolutely no comparison to the y-pipe which is by far on of the best mods made for the money along side of the cold air intake. I think it's its all in your heads especially after spending the $400 plus for the exhaust.

 

You might be right about a catback in comparison to all those other mods. A CAI and Y-pipe go great hand-in-hand... then a b-pipe and keep your stock muffler. Does anyone know about those racing "black cats" from custommaxima.com? Anyway... I think I'll save the $400 from that catback and then wait for another $200 or so to get that MEVI. It looks awesome in the engine bay with that cover.

Catbacks? What's the use? They're really only good if you have NOS, SC, or Turbo...right?

 

That is my concern regarding the Y. I like the power gain reports of the Y, but I don't want to F with taking the ypipe on and off every year for inspection...

 

Before I put on the catback, I had the PRCAI, and the Budget Y-pipe. My air flow was opened up because of the intake & y-pipe. All that was missing for a full free flowing exhaust was the catback. I noticed a much bigger change than you because I had these two mods put on prior. Obviously putting on a catback alone isn't gonna do much for you if you don't have increased airflow thru the prior parts of the exhaust and intake. Yea, first get the intake and y-pipe, then catback. Trust me, you'll notice a difference. Like I said before, your exhaust is only as good as it's smallest piece. So do a little reading and look at your stock b-pipe more closely. So, it's all in my head? No offense, but I really do not think you understand the basic concepts of a car exhaust.

 

just stop f-ing around and just do it. saves time. i did the same thing. just do it already and be done with it. it really does work! trust me it's all good

 

would you recommend the Borla over doing the whole nine yards with Greddy? I'm talking about performance gains for the buck...

 

i think he forgot to mention it, but hes already got the prcai with a cattman y pipe and he still felt the loss after putting on the apex.

 

Maybe he's one of those people who never revved it past 5000 rpm

Also, I don't know how it would feel on an auto maxima. Since I have a 5spd, low end torque isn't an issue.
Even if he has an auto, a catback would be beneficial.

 

hes 5sp and he takes it over 5k on a very regular basis.

 

HP for dollar, go for my setup. my whole exhaust from the ypipe back is T304 stainless (minus the stock Sbend and welds the shop used to install the borla) and it costs less than the $500 that the nonstainless greddy goes for. you can get an even cheaper setup if you opt for warpspeeds non-resonated bpipe (which probably fits better and eliminates the stock Sbend than the courtesy nissan SS bpipe). skip the test pipe or get a non-SS one and it's the best bang for the buck exhaust you can get!

 

cool, thank you! i just need one more power mod before i hit up suspension.
