i got a 2002 3.8 mustang v6....im planning on upgrading my exhuast to get a lil horsepower but im not sure what to get....can anyone tell me which system would give a beter result on a singel or dual exhuast....what would be the difference on the two exhuast....

 

I don't know much about the 3.8's but I would think a true dual system would be less restrictive.

 

h-pipe with dumped magnaflows, its louder but really tame at crusing and loud when at wot. my buddy has this setup with mac long tubes it sounds ok for a v6.
