'12 LFX Cat Delete
Anybody heard anything about this? Would it really be beneficial? Since it bolts directly to the cyl. head, improving flow here would be similar to adding headers...but then again, it might not improve much. Thoughts?

In my opinion it would definitely be beneficial, and I think someone like SOLO needs to offer this soon. Their HFC + resonator kit for the 2010 and 2011s was dyno'd at an additional 15 HP over stock.
Have you looked at the tube before the cats? Is there a flange there that could be unbolted, or does the tube go straight to the cat as one piece? You'd think GM would have put a flange there to make changing the cats easier, but maybe not Anyways, I think this is really the LFX's best chance at getting gains similar to LT headers on the LLT engine. May not be quite the gains, but you guys area already starting out with more power anyways. I'd bet 10 to 15 rwhp with something like a SOLO HFC would be doable.

Well there are four NUTS (so even after soaking them with PB we're gonna break those rusty studs lol) and then the cat unbolts from the head. Then obviously disconnect O2's and the whole thing drops out. (Only a muffler clamp connects it to the rest of the exhaust.)

I'd like to see your theory proven, rather than accept the "butt-dyno" results. Frankly, I'm skeptical. Why do you suppose bigger downpipes will help? Why are the stock downpipes the size they are now? John B.

I don't see how you couldn't get gains from removing the cats, or at least adding HFCs. Its been proven on the LLT.

Magnaflow maybe, flowmaster.... Uh no.
Have you thought about a magnaflow resonated x pipe? It will probably do exactly what u want |

yeah i was told flowmaster sounds bad and that resonater would muffle the sound nice.. but i didnt want to put more ristriction but its better than putting the cats back on. what magnaflow though?? i wana try gettn the largest maybe? for that DEEP tone

The one I'm talking about is a dual in dual out that people replace the h pipe with. It reduces rasp drastically. I'm sure if u do a quick search you'll find it since so many have used it. I'll try to get a part number
