OK y'all, I got my y-pipe in, my RVM Pulley and a CAI form warpspeed on the way. I have couple of questions. 1. Will the y-pipe increase noise on my car (I have a stock muffler. 2. Do I need to belts for the pulley? 3. Is it necessary for me to make a hole in my fender wall for the CAI, is it in my best interest? 4. What kind of HP gains should I get out of this? I doing this kind of behind my parents back ;-) so I'm going to keep the exterior of the car stock. Hence "SleepyMaxx". Well If anyone can help I'd be very thankful. :-D

 

• Yes, but not by much... you will notice it a little(your intake will be a LOT louder than your Y, trust me)
• i am not sure, but I think so
• Yes, and if you HAVE the CAI, then YES
• I would say about mebbe close to 20 @ the wheels!

BTW, you are not gonna notice full gains from the Y-pipe for a week, so if you don't feel that much of a difference at first, keep that in mind.
