I got to readin some other posts about exhaust and read one about a "too big" exhaust would hurt the velocity of the exhaust gas exiting (Joe if you're readin this, you was in on the post I'm reffering to). I got to thinking about some exhaust tips I've seen on other newer diesels. The tips have about four flanges bent INTO the exhaust tip. Looks like it was designed to pull air into the tip of the exhaust to creat a vaccum to create a steady flow of exhaust gas out of the engine rather than going back towards the engine. How far off am I?
yep.. to Paraphrase what I said in that thread.. at some point, with a "Daily Driver" engine that has been Mod'd [some], like we, for the most part, have done or will do... Harmonics comes into play.. with exhaust pipe diameter, length and flow design.
If you think of it in terms of... What "Headers" do for a gasser (?).. Pipes of equal length and design..that "Tune" the exhaust flow.. for the specific engine.. to achieve the best Flow.. at the end of the Collector pipe.
Go to BIG ? you've lost the effect~effecientcy. (Looks good though
) To Small (?) It could be.. choked off.
Make any sense ??
A good, strait, clean 4" exhaust with a Flow Thru type muffler*.. is as good as it >needs to be<... on these [Daily Driver], PSD's. JMO guyz.
I'm not a "Guru" on the subject guyz... nor do I pretend to be.. My inputs on "Stuff" just comes from 50+ years of Tweaking/Building engines, that I either towed home, with Parts in a Hefty Bag.. or drove home... with a Trophy in the Passenger seat.. and [Somthimes].. some money in my pocket (not that often though).... With.

*or strait pipe.
