Hello club240 forum members,

I have a quicky little question, hope to get some good suggestions.

I recently bought an HKS Hi-Power Cat-back for my 91' 240sx. The cat was originally for a s14 model, i think a 95'. The question is, will it be able to fit on my 91' with no problems? Will it lose performance? Any custom mounting and welding will be done? Thanks.

 

prolly wont have any negative effect on performance...and for fitment...y dont u just go try it on?

 

I would think not but like Ayuaddict said try it since you already bought it. I know that sr exhaust will fit KA but I dont know about different Generations.

 

This is kinda off topic... but where can i get an 85mm (piping) Hi-power exhaust for a 97-98 240? all the ones i've seen are 65mm

 

Get an exhaust for an SR for 97-98 if you could find it...Those should be 85mm cause of the turbo

 

yea u have to find the silvia exhaust for ur s14 and year 95-98 will work the same, it will be the 85mm piping
if u search for a 240sx one it might only show the 65mm one
they both work the same

 

I'm pretty sure i have 3" piping from the catback, but i dont know what i have from the manifold. Isn't it stock 2.5? I want to buy headers and a cat, but i was wondering how i would do that since i have to go to 3". I havnt' had really time to see how my catback was installed. any help

 

so... an sr exhaust will fit on a ka 240?

 

yes, but due to the piping being larger for the turbo motor it will be alot louder on the KA

 

Yeah larger piping on NA equals.....VROOOOOM VROOOOOOOOM *blues and reds flashing behind you*.

 

^^ HAHA yeh thats so true, my friend has an Accord like that and he's always getting pulled over for it.
(off topic)

 

can you get silencers for it??

 

HKS for s13 and S14 are diff i got mine and my friend and i got it on he has the same Hi power for his s13 and his had alot less placement holders and just overall looked diff he said.
