Joker1315 Posted March 31, 2013 Share Posted March 31, 2013 Does anyone have any problems when you installed aftermarket exhaust and DP on 4th gens? I have STP intake as well and want to let it breathe a little more by opening up exhaust with an Invidia DP and SPT exhaust. I have a feeling this would throw CEL's because of the changein exhaust flow. PLEASE HELP! Link to comment Share on other sites More sharing options...
JJr Posted April 1, 2013 Share Posted April 1, 2013 I know it will need a stage 2 tune. I just threw a CEL by changing my mufflers LOL Link to comment Share on other sites More sharing options...

fahr_side Posted April 1, 2013 Share Posted April 1, 2013 Get the car tuned before you do any damage. Next time you decide to buy mods, research first.

fahr_side Posted April 1, 2013 Share Posted April 1, 2013 about that oil smell. it might be from my turbo to dp gasket. And it could be that things are getting hotter than ever before, due to you running lean because of that intake.

iNVAR Posted April 1, 2013 Share Posted April 1, 2013 Nono, that's another guy. He just threadjacked/derailed this one. He had another thread where he said he swapped his catless for a catted DP and noticed an exhaust smell, then suggested his cat was contaminated with oil and that the smell was coming from there, and that he was considering dumping gasoline down his DP to clean it out. I pointed out to him that exhaust exits out the rear by the mufflers, and that if he's smelling exhaust from his inside vents while driving at highway speeds, it's not gonna be "oil contaminating his cat" and it's much more likely that the smell is from under the hood, possibly from a leaky oil return line dripping oil onto his UP and the smell is getting sucked into the HVAC intake in the cowl. He might've loosened the line a bit while swapping DPs. For some reason, his thread got deleted... possibly from embarassment. Link to comment Share on other sites More sharing options...
