I just recently bought the apexi ws2 muffler after reading all these great review
but now that i have it installed it sounds kinda like a fart cannon when i push it.

i have stock headers and high flow cat...would adding a resonator eliminate the sound or is that just how the exhaust is

 

The WS2 comes with a resonator. Did you not have the correct mid-pipe?

 

Your "hi flow cat" isn't helping your situation.

 

is it used or new? also is it a real apexi? or fake?

 

I bet it's a knockoff.

 

/ebay

 

Highflow cat/ knockoff/ebay isn't going to be the issue...op says it doesnt have a resonator. <------ ding ding ding ding

 

its real it has has the stamp and everything.....its used but in good condition....i dont have the midpipe

 

op...see post #7

 

So you bought JUST the muffler? i would say resonator should help :3

would have been a better deal if you would have bought the whole cat back kit... but hey everyone is on a budget.
