I put my whole new exhaust system on back in july. I put on a warp y, high flow cat, resinated b w/ muffler. Now recently I have noticed its loud right underneath the engine, and not much noise coming from my muffler. When i step on the gas and look under my car all my exhaust piping moves? Does that sound right? How would i check for an exhaust leak ? Would something be broken or not sealed right since its loud right underneath the engine??

Has anyone else had a problem with warp y pipe?

 

No that doesn't sound right. It's probably just that the Y-pipe is loose from the stock manifold. Beter check that. If you say the noise comes from under the engine it has to be that the Y pipe isn't attached properly with the manifold.

I have the WP Ypipe and never have I had that problem

 

Yea, ill check that, Is it possible it could have worked itself loose?

 

Well if it wasn't bolted on tight enough during the installation then yes it could've worked itself loose.

If it's loose then this is why all of your exhaust moves when you accelerate the car. And since it isn't sealed in correctly most of the exhaust leaves through the manifold instead of downstreaming through the Y pipe and finally through the muffler and hence making the noise under your engine.
