i am new to the forum & have read quite a bit on exhausts. i installed & welded my own exhaust & thought it was true dual. (no H or X pipe). are exhaust with & without an X pipe both called true dual? also i read about drone, what is it? thank you for any info.

 

They are all 3 called duals,. the x and h are just called a crossover.

 

thanks for the response. i just happened across the exhaust guide & that explained alot too.
