1993 240sx KA24DE header and straight 3" exhaust

[Shady2293]

suspension doesn't seems so stiff Lolll

[EmperorBenzRx8]

man, that sounds so deafening to the ears haha. How's the drone?

[OptimusP]

i used to be catless on my s14 with aftermarket dual, shit booked and was faster than most sligtly modded s14s with my stock POS motor, i put a cat back on for emissions and now the car has more torque on the low RPMs thanks to the backpressure but now the car looses torque on the high end although the cat muffles the raspy sound it sounds amazing.. i need a 4-1 header to get that power back.

[thomash1955]

nice way to post a completely incorrect comment dude. its not a 2 stroke. no back pressure necessary....... plus KA's are bulletproof man. noob

[TokyoXtremeDrifter]

[countanes]

@BarelyLegal23 Thats why a drive an volvo 244 for about 5000kr (450$)

[DoubleOhFresh]

listen to that ferrari PURRR :D

are your headers a 421 or full length?

[griplimit]

n/a or turbo, back pressure is never a good thing for performance! it is if you want to keep it quiet. you can check any tuner magazine on different cars, both horsepower and torque are increased!

[lordmace2001]

Nice way to blow up your engine.

Get 2.5 and a muffler you need the back presser.

[240sxdann]

Nice way to not know what your talking about. Go ask anybody that has dyno'd a KA24DE engine, 3" shows better gains over 2.5". it has a muffler and resonator now anyways.

[15g3k]

2.5 is better with AEM intake I heard. but 3 vs 2.5 is debated with every single car manufacture, isn't that interesting?

[darkmunchkin]

3" is perfectly fine.

[outlawstar98]

LULZ!

Dan dont you want a turbo? wait dont u have a turbo?? i forget LOL (not installed that is)

Turbos don't like back pressure there lordmace, The less back pressure = happier turbo.

On a N/A set up you could lose like 1 HP from a 2.5 to a 3" setup since NA you want at least some, but you don't notice anything at all.

[240sxdann]

3" actually has been proven on the dyno to gain better power on these specific motors. On many other cars it is not helpful, but with these it is. And I'm now running an 18" vibrant resonator and a blitz nur spec muffler.

[ChuukeseStink]

Was there a big in increse in TQ or HP when you straight piped it?

[240sxdann]

I dont really know. When I got the car it had an open header haha

[240fun328]

DUDE That sounds EXACTLY like my 240

Headers Test and a Strait catback

I fugging love it! and my car is stripped int he back with no sound deadening, and a welded diff

Try Daily Driving that! haha

But i get pulled over too much :(
