Eventually I'll be taking out the motor from my 94 hb 2wd for a teardown and refresh. I was wondering if getting a new exhaust manifold and full exhaust (rusted out) would add any power gain? Would a 240sx ka24e manifold fit the truck ka? The truck is just a dd, i don't want a loud truck and still decent mpg. If stock is best, I'll just stick to that. I saw this for the 240sx ka: https://www.protuninglab.com/hds-ns13.html
Thanks for the info. |

You might be able to get a couple HP from a header. A header will likely change the exhaust note a little but with a nice quiet muffler it shouldn't be much if any louder. Headers work best when used to support other mods and by it's self it may not make much of a difference. Or it could make a noticeable difference. All depends on what else you do.

Any recommendations for headers? That link is currently out of stock. The only concern for using 240 ka24e headers (if applicable) is the routing of them down under the cab. Not sure how it compares to one another.

I have heard freeing up the exhaust on these trucks frees up some ponies but if it isnt a significant amount im not sure its worth it. I myself have a 97 hardbody so I have to work around two 02 sensors. For me a thought was to do a header and 2 1/4 exhaust from there back with a thrush muffler ( sounds very similar to a flowmaster at half the price ) and then just ad a 02 bung for the down stream 02 sensor
