I have a fairly decent drive home and it always gets me pondering engine and car improvements. I'm convinced my old rusty exhaust system is choking the life out of my 914. Having put SSI HE's and an M&K muffler on my 911, I noticed what an improvement to performance changing one's exhaust can make.
I've looked at all sorts of options for my teener ('74 1.8) and that got me thinking. Why do headers have so many curves and HE's have more subtle bends to them? Couldn't headers just go straight back to the muffler? For a two in and one out muffler. I know there's a reason. And I'm sure it's performanced based. I'd sure like to know. Thanks. |
