I recently replaced my stock exhaust with magnaflow cat-back and saw how pitiful the stock y was so i replaced that. I noticed a big differance at first and then the next day it felt like the power was gone. there is a deep noise coming from the middle were the y pipe and cat back hook up but it is only in 1st gear.. and sometimes at wot it feels like a mustang weak and useless.. so if anyone has a clue please inform me... much appreciated thanks

Hard to say.. best to get it up in the air and see what's going on.

btw.. that stock y-pipe isn't as bad as it looks.
