I pay $16 everytime i change my oil on my sr ................... Delvac + K&N filter = pure win.
I run a cat on my sr and i haven't had a issue yet. I half to around here the home owners association makes me. If i take it off for even a day i get told my car is to laud and i got to park it on the next street over.

Yea actually i heard about the delvac the same way but some more advanced racers but was a little uneasy. I guess the next time i change my oil thats what im gonna do but the temp does change pretty drastically in new york so 10-40 for the winter now.
Also i doubt a cat will make the car Sound different if you still have your resonator and mufflers in. I dont think catalytic converters fluctuate tones or frequencies just the amount of debris and fumes cars emitt.
