i got a 93 f-150, 5.0. right now i have stock exhaust, except its a turndown right after the muffler. im thinkin about buying either a dynomax welded muffler, dynomax bullet race muffler, or a magnaflow muffler. im going to do a turndown after the muffler again cuz i dont really like the look of any tailpipes or turkey shooters(out right before the tires). so i was wondering would it make a difference loudness wise if i would go for the single in-dual out muffler instead of a single in-single out muffler?

 

LOL I GOT A TURKEY SHOOTER... i know them as "weed burners" HAHA and well i wouldnt think it would matter... if u get a SI/DO it wont hurt if ur wanting it to be louder. Im not a big fan of the exhaust pounding under the cab thats i i went with a cheap and easy "TURKEY SHOOTER"
