Question '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.)

Good luck.

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?

I don't miss growing up in Peoria, IL. Nothing seems to rust here in Phoenix. I can unbolt exhaust systems that are 20 years old without problems here...as long as they haven't been 'there.'

I really don't think I'd go with bigger than stock pipes to replace the cats, and instead go with the stock size. I can't say forsure, but I'm guessing it is the same size as the beginning of the catback...which is 2.5"

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

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

Well if it were me, id take it one thing at a time. I'd try the x pipe and see how u like it then. If u want just a little louder, you could delete the mufflers and straight pipe or put some glass packs. If u want something more, then u could start looking into deleting the resonators.

yeah i thought taking out the cats would make me happy but terribly wrong. but yeah i want a nice deep tone. so ima go with wut u suggested. add resonated x or the magna flow resonated plus the magnaflow mufflers.. might as well get that all together so i dont pay later to weld and cut allover again . i would be happy though if i can just get an axle back .but im not sure if itll stop the raspy sound

The actual cats are the only thing in my exhaust that's still stock because I didn't want to have to deal with them yet. I removed the back cats (the ones AFTER the o2 sensor) and everything is 2.5" all the way through the exhaust and I think it sounds great, but not that loud. Since that's what I was going for, I was happy with it. I'd be interested in hearing how yours sounds after you're done!

Removing cats will definitely make the car louder and raspier, the easiest thing to do to get rid of it is to put helmholtz chambers on.
