This catback is awesome in all respects except driving around with the windows up.

I've got some interior cabin resonance right around ~1500rpms. At all other rpms, things sound fine.

Any solutions on how to remove/reduce this resonance? Would installing a bullet muffler in the I pipe help?

btw, the catback isn't hitting/rubbing anything.

thanks,
Steve

I've got the same setup. The sound will change a little with time. Roll your windows down. Really about the only thing you can do is put in a dynomax bullet or a glasspack.
I didn't notice any cab resonance with mine (not to rub it in).
