I know there is a lot of discussion on this, and I have read all of it, but am still indecisive. I have an IS250 with Greddy SE axle-back exhaust. It sounds great, but I think I want something with a little more growl without being too loud.

One option is to cut out the resonator, but I think this may be too loud.

A mid-pipe is out of the question, because I want to stay legal.

Another option is replacing the resonator with an aftermarket muffler like a MagnaFlow or glasspack or something.

Does anyone know what the sound difference would be between a stock resonator and an aftermarket muffler/glasspack?

Thanks

your best bet is deleting the resonator. my .2 cents

The only thing I am worried about deleting the resonator is that it is going to be loud and "ricey". Does anyone have a sound clip or video of a res delete with Greddy SE?

It shouldn't be too bad if u just delete the resonator

So, what would be louder? HKS Hi-Power + Invidia midpipe or Greddy SE with resonator delete?

My understanding is that the HKS Hi Power is one of THE loudest exhausts alone. With the Invidia mid pipe...it'll be crazy loud.

I've heard 2 IS350 with F Sport intake, F Sport exhaust, and Invidia mid pipe and I think they're annoying loud with cabin drone!

So let me ask you this. Would there be any difference between leaving the stock resonator there or replacing it with a Magnaflow glasspack or muffler?
