Alright, well I got my exhaust welded on this morning at a very reputable shop. Bought some mandrel bends from Summit, Magnaflow Street Series muffelr and 31" Thrush in place of stock resonator and cat. My car pops like crazy at low RPM's when I release the gas pedal! Is there ANY way to solve this? All the welds under the car are kick ass and I would have to highly doubt that they leak. I searched here and SR20deforum.com, but no one has figured out why it does it. All they say is "Hey, I have that pop too, it's so cool!". Now I"m not saying it's not cool, but it isn't when it does it ALL the time. I'm sure others of you have it, but does anyone know how to fix it?? It's just buggin me! BTW, I'll get pics up. And I put my tach on last night, you guys will love the mounting spot . I'll take pictures later when I go to my dads house...digi cam = yay!
