Hey guys i got a 98 expo with a 5.4 currently has not cats goes straight from the manifold to a two in two out magnaflow with dumps, its loud as all hell but im just not as happy with it as i know i could be, im thinking about gettin some pacesetter headers and throwin maybe some straight tube cherry bombers or glass packs in it to a side exit, let me know if anyone has a similar setup or maybe some advice...thanks

 

just have your existing Y-pipe modified or run dual flowmaster 50 series mufflers with an H-pipe

if your trying to go the cheap route go to a midas shop and get some ravin (raven) mufflers with either an H or an X pipe


many people run either an H pipe or an X pipe to help keep the rasp down when running no cats

 

Headers will surely volume it up, but a cheaper method would be a muffler swap. If you swapped to dual 2 chamber Flowmasters or Dynomax Bullets, oh it'll hollar loudly through the neighborhood for sure.

 

thanks tera but there is no y pipe its got a seperate pipe coming from each manifold and a two in muffler

 

Dual pipes. I would call it true duals but its not if it goes into 1 muffler.
