Hi,
I just had a few questions. If I get a new Y-pipe, cat, and B-pipe from warpspeed performance, will it still be able to pass smog tests? I got a new muffler, but I wanted to change out at least the B-pipe before I have it installed. I guess one possibility is just getting the WSP B-pipe, and having the muffler welded on to that, but I kinda wanted to replace the whole thing. I was just wondering if it would still be able to pass smog. Also, does anyone know the diameter of the piping on the stock B-pipe? The inlet for my new muffler is 2.5". Thanks for the replies!
One other question, on an unrelated topic - My car makes a funny humming sound, especially after high speed turns. It's hard to hear from the engine bay, but from the inside of the car it is easily audible. If I had to guess, I would say it sounds kinda like a belt somewhere might be worn or something. It makes the sound more audibly when I'm turning, but it's not tire rub because it still does it after I've straigtened the wheel, and even after I've stopped completely. It makes a slightly different noise under acceleration in 2nd and 3rd gears - it's sounds a bit like that humming noise cars make when they go in reverse. I guess that's not the best description, but if anyone can help me out, it would be appreciated. Thank you!

I think that you will be able to pass emissions, but since you live in Cali., I don't know? I'm pretty sure they're strict as hell about emissions. As for the sound, it could be your suspension or your axle? Make sure nothing is leaking and check all of your boots for grease marks or something of the such.
