      Popped these bad boys in, a noticable difference for sure. I swear it even sounds better. Tits.

        Torsen 3.46 should be nice and help with mid range punch.

        What kind of injectors.

        Next time you see Bruce, shake your head at him from me

          I'll probably be shaking my head at him for something else even if I forget.

            Nice work mate!!! ;)

              So I'm trying to get my exhaust sorted out.
              Right now I have the 14815 magnaflow muffler, though it sounds great above 3.5k RPM, I just absolutely hate exhausts that have a resonance at cruising RPMs. More RPMs & more gas should equal more sound. I think I'm going for the IE catback instead (from eBay though...) but I would consider a nice muffler with custom tubing if it doesn't drone.

              What are your guys' opinions for headers? My lazier than usual smog guy seems to have caught some heat for being lazier than usual, so I'm trying to find something friendlier for CA smog. I might settle for the IE shorty headers, because I can easily remove them come smog, get a shop to weld a flange so I can swap them out easily every two years.

              It also dawned on me that long tube headers would make it difficult to install a cat, at least in the stock location. Not a fan of my car smelling like garbage and intentionally polluting just to gain like 1-2 hp. What's more, is it seems to be incredibly difficult to make them interchangeable with a stock system come smog.

              I'd appreciate any input or advice. Anybody running the shorties? How do they sound?

                Do you necessarily need to place the cats in the stock location? Are you still considering ITB's for future modifications?

                I've always thought Digger had quite a nice exhaust setup on his car, and he runs two cats that seem to be placed a bit farther down stream. A similar setup might keep you within emissions and keep future performance goals in mind?

                  California smog is very strict, by the book they won't let you touch anything from the intake to the catalytic converter unless it has a carb EO number. I could probably get away with it a little further downstream but it has to be a single cat if that's how it was factory.

                  As for ITBs, my car isn't even close to done right now so it's kinda hard for me to think about it lol. By the time I'm ready to do that I'll make sure I have a solution for smog beforehand I think.

                  I want to avoid redoing my exhaust like 3 times if possible. Are the shorty's just a total waste of money?

                      Just impulse bought IE long tubes because of the black Friday sale lmao.

                      Did my first full oil change. If anyone was curious this is what a magnetic drain plug looks like on a brand new motor...



                      It's got some shit on it. Not too exciting

                          those IE are longtubes. should make better torque than shorties lowend and midrange

                            this is really making me want to build an m20. Have you figured out a smog situation yet? I may have a few lines on lazy smog guys around oakland/san leandro if you need em

                              came across your thread. I recognize that car! This is what it looked like summer of 2016. I grew up a few miles down the road

                                I thought long tubes will give you better power/torque in the upper RPMs while shortys are better in the lower RPMs?
