need catback opinions please I currently have LT's ORY and an LM1 catback with a Magnaflow 3" bullet muffler....car is LOUD and somewhat poppy (lacks good tone). I was wondering, should i just add a different muffler to the system in place off the bullet muffler, but wth would fit there? Or, should i have the LM1 cut over the axle and put in a "normal" crossflow mufler, and if so which..like the Hooker. Or does anyone here wanna buy my LM1 with the polished stainless Magnaflow muffler and i just buy a new catback? Is hooker about the best bet with h/c/i car for sound?

You can try the SLP powerflo conversion kit (p/n 31086). It will add two small straight-through mufflers in the tailpipes.
I have this kit on my car and it sounds very good with my h/c package + headers + high flow cats + loudmouth II resonator. It's loud but not too much, and deeper in tone than my original catback (dual-dual).

Here's and old post with pics of my exhaust:

BTW you can also add high-flow cats. It will help to improve the sound of your car.
Good luck!

The stock OEM muffler cost him 19 rwhp. But that's on an LT1 f-body. I don't know for an LS1, but it should be very similar IMO.
