A lil problem


A few weeks ago I unboled my exhaust to see if it made a difference. Well it made a lil difference my friend was slugging with his 04 Stage 2 Redline unbolted and won a few times. I had a CEL so I put it back together and reset the battery and it went away for a few miles and then it came back. I also have the airbox mod done. It has some slight hesitation in the low RPM band but it straightens out after a second and drives normal. What do you guys think it is?

 

i don't understand what you did...

 

im with him...but if you ave a cel then stop by autozone and get it read

 

I unbolted my exhaust after the cat, on the flange....

 

What CEL did you get? Number or text?

 

Have not read my codes yet. Does Checkers(Schuckers for you down south people) read codes for free because we dont have an autozone here in town.

 

uhhhhh...... and what made you think that was a good idea???

are you sure you bolted it back up the right way?
