Customized Y-Pipes / Resonator Delete

My135 · 06-12-2009, 01:22 PM

I am thinking about remove the resonator and replace it with a customized Y-pipes. It looks like Magnaflow is selling a Y-pipes (see below) with differnet inlets and outlet size. I think it may work with additional piping and welding. Have any one gone this route with a customized Y-pipes instead of completely replace the mid-pipes? Please share your experience here. Thanks.

Would get pulled over in an instant in cali. No bueno

It's only a resonator delete. The performance exhaust has resonator delete and is perfectly street legal. This is legal. There are probably more modified cars running catless in cali than in any other states!

I would expect some drone after removing the resonator. Isn't that what it is for?

This will be very similar to the rr system. Unless you know someone who does welding and fabing for cheap your best bet is to pick up a used rr system for $350-400 shipped.
