Hey guys, I installed an Espelir Catback on my STi two days ago. Before at WOT I would hit about 1.2-1.3 bar. Now I only get to about 1-1.05 bar. What could be causing this? An exhaust leak perhaps? How can I check if it's leaking? I love this exhasut, but I htough a 3" catback would ADD HP, not make my car feel slower! Am I supposed to reset the ECU? Or is it ok not to? (I havent yet)! I really appreciate any help!

might as well try resetting the ecu. there's more air exhaust outflow so it may have disturbed the stock setting. (who knows...)

i had to reset my solara when i put the jic on.

 

Thanks! I'll try it! I just hate resetting everything afterwards...lol
