Do you guys get weird noises from you engine bay with a catless system. Iam hearing a Squeaky sound, but it doesn't happen all the time, and sometimes the turbo makes a growling sound when it spools down. Iam thinking its because its a 3 inch pipe that i can hear things that i couldn't before. And it doesn't sound like a good growl, more like a nasty rattle at times.

 

What about my question?

I don't think its the rsr sytem.I think its just because the piping is bigger so i can hear new sounds, like the turbo spool. But still get that sqeaky sound and the rumble sometimes. I dont know if the piping is to big so it rubs underneith the car making that squeak sound. Its a 3 inch and fits perfect.

 

I'm hearing wierd faint squeaking sounds also coming from the engine bay. Just noticed the sounds here recently and I think it might just be a noisy belt under the hood.

 

I've noticed in my friends car, Fatal Velocity, whenever he down shifts and lets the engine wind down, it sounds like a police siren. It's really weird. Not sure if that's the sound you're describing.
