Exhaust H-pipe
Hallo
I'm puting new exhaust on my 75 dodge w200 with 318 engine. I'll put 2 pipe exhaust that I'll custom build. Is it a must to put the H-pipe to connect the pipes. Is it the H-pipe in that engine runs better or why??
I never quite understand this, becouse if I look on some already made exhaust systems for the cars, some has the H-pipe and some don't.
thanks
