alright any and all would help. any comments even yes or no is fine. i have a y-pipe, test pipe, and 2 and 1/4 B pipe. i have the stock muffler on there also. so i was wondering, is the stock muffler holding me back from power i should have with those mods?? in other words, would a different muffler be better to let loose some more power, strait through and or some other kind. because i have the worst low end ever. ihave a VE auto. its been better but when i put those mods on it got worse. any help is appreciated, i just want my low end to be better so i can get a good launch. thank you.

 

mufflers doesn't add that much power. typical gains are like 1-3 HP

 

sounds like a knock sensor problem

 

thank you subs, it was my knock sensor. i did the bypass and it was noticably different. so thank you for mentioning that.

 

ok wtf. i did the knock sensor bypass and it worked. then the next day it was back to being crap for low end. i changed resistors to see if i burnt the other one, but that doesnt help either. what could be wrong here. it worked before but now it doesnt?? im confused
