Headers and exhaust problem Hey all. So during the week I recently had my pacesetter long tubes installed and a 3in dual exhaust put in. Now, there was some confusion at the exhaust shop and he didn't get what I wanted and made literal, true duals, no cross pipe on it. I asked for and x or h pipe, insted I got a ls1 that sounds like a farm truck. Luckily, he is going to fix his mess up and install an h pipe either tomorrow or Tuesday. But so my question is, my car seems so much slower.. Is it caused from the straight pipe duals or do you think I have something else going on? He deleted the EGR, i don't see how that would cause it. But I have 2 codes being thrown. 140 and 160 I believe. It's no activity on my o2's, we discussed deleting the rear o2's since they are not needed. But I'm at a loss as far as what's wrong. Any ideas?

Is this true? Safe mode for egr or rear O2's? I deleted mine with hedders and have not had them tuned out yet but i have not noticed any eccessive rich condition.

no it wont. the pcm will throw codes for no egr and no rear o2 but they have no effect on performance. the only time you will see a loss of power is with the front o2's. it is common for people to think the car is a little slower after headers because they shift the powerband around. you should get a tune though to maximize the mods
