Where can I find a stock exhaust for a VTEC? I can't find anything here, eBay, various classifieds sites, etc. I'm pretty sure a 5th gen won't fit a 4th gen...right?
a 96 VTEC exhaust on a 94 VTEC won't detune any engine mods, right? Only the ECU determines it? I've heard there's something extra in the exhaust of 96's that determines emissions?

There is an extra bung for a 2nd O2 sensor for OBDII.
Just plug the hole with a short bolt and your good to go.

So you dont have a loud annoying buzz/hiss.
An oil drain plug from an early model GM vehicle threads in the o2 bung quite nicely. At least I think it's GM. Don't know...just go to your local parts store, and go to the oil drain plugs and find the right one.
Wait, the o2 bung is in the cat, not in the exhaust, what are we talking about?
only if your running odb2 does the engine/ecu actually have the sensor that goes in the exhaust.
since your running 94 your engine is odb1 so it doesnt have the sensor. meaning, you'll have nothing to put in the exhaust so it'll be an open hole ... creating an annoying buzz/hiss.

You still said "An oild drain plug from an early model GM vehicles threads in the o2 bung quite nicely..." But you did correct yourself.

They are not the same. The bolt pattern on the cat is different. You can easily modify one of the other to fit since the piping dimensions are the same.
Originally posted by alvin the bolt patterns are the same. I know because I have an Si and I bought a VTEC exhaust.... still fit...
Many members have posted that one of the three holes needed to be modified for the exhaust to bolt up. Why are there different models then for si/s and vtec exhausts?
weird... my N1 fit.... i remember because i lived in ak when i installed it... it said for vtec models and i was like SH!T its the wrong one, i didnt want to go through the trouble of shipping it back being in alaska and all so i called the company and they said it was the same... turns out they were right....
