3'' catback on ka24de?

[nlzmo400r]

well guys, id like to get an Apex i' N1, as i like hte way they sound, or possibly a HKS Hyperback, but im pretty sure hte apex is a 3inch, i plan on going SR within about a year to 18 months or so, and id have to buy a 2.5'' now, and then have to buy a 3'' when i get the turbo engine. Should i just get hte 3'' or would it totally suck down my low end?

[AZhitman]

It's gonna have a minor effect on your bottom end, but it should actually free up some topend power...

Hell, it's only for a while. You've lived with it being slow all this time...

Let me know if there's anything I can do - I know "this guy" *ahem* who builds some pretty kickarse *ahem* catbacks for the 240....

I have a apexi gt spec and thats close to 3 3/4" piping on my stock ka24de and i haven't noticed a reduction in low end whatsoever

Any specific reason why you have that enormous exhaust and a cone filter.. I'm assuming your looking to boost right?

I think he means the tip from the look of it, piping is 3" maybe. Pic could be misleading, let us know.

[FrEaK]

No thats the actual size of the piping... it's on the Apexi site...

[MECPInstaller]

yeah its 95mm roughly 3 3/4 i believe and the tip is 115mm or close to 4 1/2 and yeah when i get the money i wanna try and eventually get a turbo kit.

[jdmfreak]

Damn thats pretty big for an N/A!

[Altiman94]

might as well get the 3" now so you don't have to spend more money later. I'll be going with a 2.5" later this week, but I'm not planning on boost unless I can get a CA clip for around 1400.

[bentsprocket]

I have a 3" catback on my KA and didn't notice any low end torque drop. I thought it did and put a tunable silencer(junk) in the end of it. There was no difference so I took it out ASAP sounded like chit! Muffeled up sounding. I like the one I have just a alot to polish.

Here's a ? Do you like straight or angled exhaust?

[USDMSTALKER]

I have a 3inch Blitz Nur spec and love it. Sound awsome and gets lots of stares because of the sound. But have an sr waiting to be put in

[TurboKA37]

i just but my exhaust in two weeks ago w/ 80mm piping. didnt notice any torque loss but did give it some better top end. ill be going turbo soon

[MECPInstaller]

i bought the gt spec with intentions to eventually go ka-t with either the greddy kit and fmic . Also i bought it for the wow factor it seems to give people. Nothing like a girl saying oh my god thats huge about you then realize shes talking about the muffler tip:( The only problems i'm having with it is that it is very loud which is cool but at times its alil to loud when your trying to get around town without attracting cops (small town with cops that have nothing better to do) And when you downshifting it backfires like crazy in quick little pops its a good deal though was 469 at enjuku and 85 for shipping to illinois and got here in 5 days.

I got an Apexi N1 and love it.

[marshun]

i say just go with the 3" now since youre going to boost it later. i mean why spend more money than you have to?

my 240 is just gonna get 3" straight pipe. its only for track drifting anyway.

[nlzmo400r]

well im just going to go ahead and use the 3'' since all of you guys say u didnt feel a drop in low end. Oh, and just for hte record, i LOVE the angled exhaust, thats how im doin mine, just gotta get it mandrel bent i suppose

[JayPat83]

so your 3 in catback sounded better without the silencer bentsprocket? maybe i'll have to take mine out then.

[irax]

im going to get like 2 3/4 or 3 incher for when i get a P&P job on my head and pdm racing cams and header and cold air intake from pasinger tirewell.. and ported intake.. but im still going to keep the stock exhaust tip i like stock looking stuff ^_^

[bentsprocket]

Well IMO I do like the sound better but it is loud azz hell. Really loud when it echo's off cars, retaining walls, bridges, and in Asheville tunnels lol. Stay off Patton Ave with it.

[JayPat83]

bentsprocket, you live in asheville too?!?

[bentsprocket]

no I grew up in Marion and Moved to Cali now I am back in Winston Salem.

[95_Nissan 240sx]

MECPinstaller...do you have anymore pics of your exhaust? And you dont use silencer do you?

[bentsprocket]

Here is the exhaust My nephew has and no problems just loud It was purchased at SSautochrome

3" catback

[SilviaS14KA24DE]

rofl wait! You don't need your apex'i n1 to be mandrel bent. it's already angled that way.

the reason they're angled is to have less bends in the piping to improve exhaust flow. usually right before the last resonator (the big canister you see) they make a horizontal pipe to make the muffler sit horizontal. Now, apex'i i believe started to not make the horizontal pipe, and instead, made it angled to improve exhaust flow, also avoiding another bend in the exhaust pipe.

[89240sx]

hmm that was the only thing keeping me away from getting aftermarket exhaust because everyone states you lose bottom end power....

well AZhitman I might be hitting you up soon on that exhaust you have the hookup for....

Do you have twin tip (s13)? Also is there a silencer? is it needed?

maybe 2 3/4? I may or may not boost in the future... I have not decided yet

hey i have an apexi n1 dual for sale. it works very well for both n/a and turbo cars. here thes link with pics..

[nlzmo400r]

I think id rather the single N1, however it is a nice exhaust, but i also dont really have the money right now. I dont wanna sound like an *******, but ive seen cheaper also, sometimes as low as 25o plus shipping in good condition, i like your 'gold' look though

I laugh every time I see one of those monstrosities grind on a speedbump or a driveway.

"Mandrel-bent" does not have anything to do with how the muffler sits. Mandrel-bent means the piping for the ENTIRE system is bent in such a way that the entire inside of the piping retains a constant diameter (for better flow).

The "angled" muffler has nothing to do with improving flow, regardless of what they'd like you to think. It's purely an appearance thing, as is that enormous canister. It is a good system, just more style than substance.

I really need to work on my "Top Twenty Exhaust Misconceptions" list for the BRM website...

[TurboKA37]

my exhaust comes out at an angle but it does not have any clearance issues. probly the same clearance as the stock exhaust. plus the one less bend they have to make gives you about 15hp
