EDIT 2: I guess you don't think this is good because it's a glasspack, right? I've always loved magnaflow's stuff though...

This is what I used for my "extra" resonator.

That glass pack will degrade over time.

Either of these would probably fit without headshields and probably be considerably more effective than a 4" body one.

I looked at the Dynomax Bullet, don't know how I feel about that...

Also looked up the Moroso Spiral Flow but IDK. I googled it and read up on it and people have reported that the spirals come undone and buzz like crazy and that they rob you of a good amount of horsepower too. I just don't want to fix the damn exhaust like 5 times.

That dynomax has ceramic sound deadening... looks like it's intended to meet basic regulations for a "muffler" on race/drag cars.

Magnaflow is probably the best way to go.

If you don't have a resonator at all now, it will reduce volume... and get rid of what I'm going to bet is a TON of rasp.

Drone is always going to happen, period. You will never get rid of it, just muffle it more. The OBX V2 and Cattman setups both seem to resonate in the 2500ish rpm range. That's just how it goes.

When I had the 3" non equal length Y-pipe installed, it only droned from 1200-1800 RPMs and was dead quiet when the cattman is normally droning.

Should fit fine in the B-pipe area behind the cross brace. Worst case you'll need to remove the heat shields so it doesn't rattle against them and possibly get stiffer hangers if you don't have them already.

You can go with a. 30" magnaflow resonator that's sure to quiet things down a bit

I don't think it will drone with a Walker/Dynamax/Quietflow nor will it drone with these 3" exhaust tip silencers.....AEM p/n SIL3000:install for street remove for track!!!!!!!

This message goes to Spideymon....."If you do find a 3" Quietflow muffler have the muffler shop copy the rear muffler section (the top picture) they shouldn't have to cut a thing on your Cattman system!

Spideymon here is where I suggested the samething concerning having a muffler shop build that Walker Dynomax VT to fit up to the slipjoint!!!!!!! This will be an easy fix...........................
