clocks Posted June 26, 2009 Share Posted June 26, 2009 Had the MADDAD EL headers installed a few days ago (along with a MADDAD uppipe and LW crank pulley, all installed by GTTUNER). Now when I go WOT I get a sysyem lean CEL. Also are stock mufflers the best way to go to quiet down my new (honda sounding) exhaust (will they match up to the perrin pipes installed now on the car?)

PhillyWilly Posted June 26, 2009 Share Posted June 26, 2009 assuming you pulled the code for the cel. what is it? running stock tune? yes the stock mufflers will bolt to the perrin y pipe and will significantly quiet it down (i am assuming you are currently running perrin cans).

PhillyWilly Posted June 26, 2009 Share Posted June 26, 2009 you probably need a new tune but im not familiar with your code. Link to comment Share on other sites More sharing options...

tommypenguin Posted June 26, 2009 Share Posted June 26, 2009 I am currently running maddad ELH headers on my car, they never caused a CEL or for me to run lean. I didn't need a tune for them when I put them on, my logs told me so, but every car is different and to say that would be a general rule of thumb would be incorrect. Any chance you can take some logs? Link to comment Share on other sites More sharing options...
