    You seemed to have some good info on my post a while back about me putting on a straight pipe 4 inch system and getting low boost codes and mad air flow sensor codes after installing it. I have not found any leaks in the boost system nor have I had any other issues. You mentioned that you have seen some trucks with this issue and it is because the emissions code installed on it. Is there any way to change this? Also have you had any luck on a fix for this. It honestly seemed that there was not air flow going to the turbo after I put this exhaust system on...I could not hear it winding up. It seems like it just needed a bit more back pressure to get going? Would adding a muffler or something help? I am just a shade tree mechanic and wanted to do this simple upgrade to give my truck a bit more performance. Just looking for some advise here. Thanks
