''X'' pipe

I posted this over on the''other'' forum regarding replacing just the resonator with an ''X'' pipe. I also thought I'd incorporate an electric cutout(s) somewhere in the install. Any thoughts, experiences etc?
Thanks

Ping Pete n Bob G - their setups are similar to your idea. Pete is using a pair of bullet resonators and they're both using the vacuum flappers attached to one of the two muffler outlets on each side. Pete said once that after installing the flapper, now he can carry on a conversation.

Now, on mine I did the SW X-pipe and muffs only, and it sounds great at idle, but makes waaaay too much - attention getting - noise at heavy throttle (for me), and then there's that resonance issue. I doubt a cutout would do the trick (for me).

One of the FBI guys, Phil(?) is using a pair of 3x18" chambered stainless muffs in place of the resonator. The claim is there is no resonance. Taking him at his word, I bought a couple ("Power Sticks") and we'll see how that works (once the machinist hatches an egg and finishes my valve job).

After hearing Pete n Bob's systems, I too am interested in a flapper. So, my exhaust is not welded anywhere yet - still a mix and match work in progress (SW headers n X pipe, MF twin tube muffs).

Exhaust systems...

I'm not really interested in redoing my entire system....just the ''X'' pipe install. I see you did exactly what I want to do by just replacing the resonator. So it begs the question about drone ......and that is what I'm trying to avoid. In your opinion would I be better off leaving things alone? (if it isn't broke don't fix it ) I'm after a deeper sound without creating a bunch of harsh noise.
thanks

Leave it alone

Had a TriFlow exhaust I bought new. Drone wasn't terrible until I installed the x-pipe. Leave it alone.

Thanks guys. I think that is good advise about leaving it alone. Maybe I'll just sneak a couple of cutouts in the system instead.
