Jack, after researching, I have no doubt the m3 exhaust system will be great to match up with the m30. The center section is actually from a standard e30 m3 (2.3 liter) instead of a sport evo (2.5 liter), but besides the fact, you have to take into account many different things. The s14 and the m30 are two VERY different engines, one revving to 7.8 RPM and the other revving to 6.2K. The s14 turns at a much faster rate than the m30 and with this among many other factors the e30 m3 center section was designed to withstand more than it's engine could put out. Another supporting argument towards that is (if I believe correctly) the standard e30 m3 (2.3 liter) had the same cats as the e30 m3 sport evo (2.5 liter) and so this somewhat proves the manufacturers put more than enough materials into the cat to make it withstand a higher power engine. All in all, I believe it will pass smog fine with the center section on, it will sound great, and flow nicely. I'm not planning on turboing the m30 anyways, the cats will be able to handle a stock m30.
Its not about the cat "being able" to handle the power or not. That cat would have to be as efficient or more then than the one that would have been mated to a stock m30 motor. The m30 is way bigger in displacement than the s14 motor. With that being said its definitely more likely to have polluted more since day one. The only way the BAR is going to be cool with a OE cat being used is if its the one that came off that e28.

I think that most are trying to help you out. Your comments like the one above only feed the fire. Remember, its your project posted on a public forum. If you dont like what's being said, ignore it and move on. As mentioned, those rails are worn bad enough that I might be concerned about what else is going on.Leave a comment:
