Ok my old car had a sohc d series and now I've got a b18b1 it has I/H and muffler but I want to increase the piping size in the midpipe. What size do the b18b1 come with stock for a midpipe 2inches? and I'd assume 2.25-2.5 inches is best for a n/a setup?

 

yes comes stock with 2"
i think you should get a 2.25 inch bpipe.. and get a 2.25 inch header
dont get diff sizes.. n depending on wut your plans are.. 2.25 is good for na i think.. 2.5 may be a bit big.. but depends on your plans.

2.25" piping is good for about 180whp. So unless you plan on making more power, it should suffice. However, I can't think of any mass produced header that has a 2.25" collector. Most are either 2" or 2.5". There is nothing wrong with getting different sizes, just as long as you don't neck down.

 

and u can go with stock itr Bpipe, they r 2.25 too

That's what I'm using on my car. Just make sure to get the bottlenecks removed.

mid 14 is easy for u bcz u have a lighter car..

 

Stock exhaust is acutally 1.75 so 2.25 will do you a world of good prob 3-4 whp. I got 2.25 on mine and its sufficient. hope that helps.

You can have one made at a muffler shop for half that price.

if you would rather have crush bent aluminum piping with crappy *** flow for half the price...or you can have a shiny stainless steel mandel bend piping with a resonator and flanges...i personally would invest a little more for mandrel bent stainless piping...your choice

Personally, I couldn't care less how shiny it is, as long as it does it's job. I always coat my exhaust systems to keep them from the elements (not that there's many elements in So Cal). I have no crush bends in my midpipe, as it was mandral bent for far less than 116. You could even have U-bends cut and welded for less than that.
