Hey guys. I have a LM1 that I'm about to take off and replace with a dual/dual from my buddies 02 SS. I know the dual/dual flows pretty well but should I expect any significant power loss? I expect to lose a few hp but hopefully nothing I feel. Thanks guys.

I wouldnt expect any power loss if anything a few HP, pretty much all the catbacks for these cars have flow through mufflers so it affects sounds, but doesn't really impact performance as far s muffler/no muffler

I swapped my LM1 for a DUAL DUAL because with my H/C set-up...the RASP was unbelievable. I didn't like driving it in the morning because it was just too loud, would wake all my retired neighbors and it's kinda overkill, not necessary! I didn't notice any power loss and at WOT, it seems just as loud as before, or damn close.

I got mine from my best friend for free. He installed a LM with a Manaflow bullet and gave this to a friend of ours that ended up not needing it as well. You can find them complete and uncut in the $300 range on tech classifieds sometimes, but they're getting harder to come by.

My brother has Factory Dual Dual on his 02 35th SS. He, so very badly, wants to invest in a GMMG Setup. I told him if he eventually does go thru with the swap that I want his Dual Dual for my Firebird.
I currently have LM1 on my car too. So I'm very curious to know how you like the swap and whether or not you feel a difference in throttle response & overall power between the two.
Please keep us updated.
