I too prefer the Stock look and when I go for a servie, I will swap the Y pipe over in about 10 mins before it goes in. Along with running 99 ron petrol (UK) I recon this set up gives a nice improvement over standard......Also the sprint booster makes it far more exciting to drive.

Yes, I did put the SL55 hose's & "Y" on mine, but it still looks OEM and it did drop my 1/4 time on a G-tech 0.4 seconds and gained about 3 or 4 MPH. But that did also include removing the resonator too. On my G-tech I'm doing a 12.3 in the 115's in the 1/4. I just don't like it when people take a piece of art and make it butt ugly for just a possable gain of around 0.1 to 0.3 seconds in a 1/4 mile run.
