i have only 2 mods done, modded cosmo racing intake to fit the lancer no problem, and the last 2 days we cut off the muffler and im gonna call it another muffler after the cat, put a straight pipe there and welded, same with my racing tip i had on my subaru but while we were in the middle of doing this, the clutch starts acting up, like its low on clutch fluid, my buddy thinks it an air bubble since i can still drive then it starts trying to stall out., im wondering what the hell is going on. any insight, im making an appointment at the dealer since its still covered.

 

what?

 

the clutch is acting up, like its low on clutch fluid, my buddy thinks it an air bubble since i can still drive but now it keeps trying to stall out.,

 

If the pipe is bigger than 3in, the back pressure is your problem .

 

troll?
when you removed the muffler(or whatever you did) maybe you removed the muffler fluid return line and you didn't notice. That could be your problem too!
