Megaphone exhaust on 4 cyl. Options

[krazykonrad]

This may be my inner redneck talking, but how about megaphone exhaust pipes instead of a muffler on a 4 cylinder? Other than being loud, is there enough back pressure in the system?



Thanks in advance,

well that straight exhaust was terrible so i made my own muffler for it. i kept the bus manifolds and used a bus muffler. made extension pipes to the inlets. I cut an opening in the muffler so i could drill out the pipes inside it make it flow better. i cut open the baffles too. I ran the original single out exhaust pipe to one of my tips and cut a hole directly in the muffler for the second tip. so its a bit offset under the car. but it flows evenly both sides since I opened up the original tail pipe pretty good inside. and the tips are placed just like they were with the straight pipes. sounds good now not too loud but definatly not too quiet. just how i like it (IMG:style_emoticons/default/smile.gif) lots of cutting and welding and drilling but only took about a day and well worth the effort
