I was just wondering what size piping i should get for the KA24DE i plan to do an SR20 engine swap sometime and was wondering what size would work for the KA24 and the SR20 i dont want piping thats too small and only good for the Ka but then again i dont want piping thats to big and only good for SR20 what exhuast do all of yall out thur suggest i pick up.
I was thinkin Apexi N1 or HKS Hi flow.

 

Wit a turbo engine u'd want 3'+ piping. And on a N/A Engine it is really loud and at times annoying to some people. I'm doin tha same thing only I'm gettin an RB20 since not a whole lot of people have em around these parts. I say get ur engine first then put an exhaust. Or get an exhaust that's 2 1/4 or 21/2 piping then sell it when u get ur engine.

Both Apexi and HKS are great exhaust. A buddy of mine has tha Apexi N1 and it sounds pretty nice, its on a Integra. And I know another guy that has a 95 240 like me with tha HKS Hiper super silcence. It doesn't make ne noise but get tha same amount of power. With exhaust it's pretty much wat ur ears like, try to go to a meet with lots of different exhaust and see which one u like best.

 

i have a n1 3" its way to big for a stock kade but you could deal with it till you did your swap its loud i have a test pipe as well...

 

you could put a high flow cat to creat some back pressure if by saying too big for ka24 you mean loss of low end...

 

i know this the loudness doesnt bother me

 

The torque loss shouldn't be that noticeable either. The KA is already a pretty torquey engine

 

dunno wether this is of any help,but on my uk s14 i've got the blitz nur spec r system,its full system with no cat on it but don't tell the uk police,and its hooked up with the blitz sus air induction kit,and car is at tuners at mo hvin a stainless steel manifold,jun cams,greddy boost bontroller hks pulleys,etc,etc,etc. sorry got carried away,the blitz exhaust system is awesome,drive down the street and its so loud people stop and stare

 

It all depends on wat ur ears like..

 

u r rite there,its all down 2 the individual! in 1 way it saved me money,as i don't need a big stereo install,im 2 busy listening 2 the engine,sad i know

 

i to got the blitz nur spec-r catback system on my 240sx(ka24de), except i don't have all the mods u do (neilstaford) just an inktake. i just slaped it on a few weeks ago and it sounds really crisp, popy and loud like u said "it turns heads" i would really like to hear a sound clip of it with a turbo or even with just some minor mods done to he engine like cams, intake mainfold, pulleys, etc.

 

its the only music i like when im driving
