I have a 95 ka24de that im working with for my sohc to dohc swap. The problem I have is that the manifold on 95 wont bolt up to my sohc downpipe.

I was wondering if a SR20 downpipe would bolt up to the s14 manifold and to my exhaust.

i dont know but if u need a stock sr red top down pipe i got one $30 shipped lmk

undesiredshoe · 08-06-2006, 01:07 AM

sweet deal...what size are the stock ones? 2.5 inches?

If it turns out that the sr20 dp can be used with s14 ka manifolds, ill buy it.

Id RaThEr DrIfT · 08-06-2006, 01:21 AM

yeah its either 2 or 2.5" somewere around there just pm me when u find out if u need it

redsuns3838 · 08-06-2006, 01:30 AM

stock is def not 2.5 inches, id say 2.

i know that DOHC KA downpipe and SR downpipe are the same. so i believe yor DOHC motor will fit a SR downpipe well

SR downpipe will fit the S14 manifold however the flange at the back is clocked differently. You'll either need an aftermarket cat with floating flanges or a test pipe that you can cut, rotate, and weld back together.

I highly recommend against the floating flange. It's the type that swivels around instead of being fixed.

I snapped mine clean off the flange just driving around normally. Then the catback fell off.

Now I run a PDM Racing cat and I'm much happier. I highly recommend them, or at least get a muffler shop to weld one on for you.

yeah if you want to install an sr downpipe on a ka. Your going to need something with reclocked flanges on the cat.
