I know there are tons of threads about this but I've looked through a FE already but kinda find myself in a weird situation. I have kleeman(super sprint LTH) and agency power valvetronic exhausts without the electronics installed yet. I want to reduce the odor and maybe keep some low end torque while keeping most of the hp I can if I install 2.5" 200cell metalic cats. I ran across these http://m.ebay.com/itm/182100539858?_mwBanner=1 on eBay and ordered two of them. It says 17" I'm wondering if I have room in between my kleeman LTH and AP exhausts and if so well I benefit from this H set up or can I some how make an x pipe. I'm not too knowledgeable so go easy senpai

is that the same diameter as the LTH and AP exhaust? PLM seem to be good quality, there was a good write up here of their headers a few years ago. There should be plenty of room to fit them length-wise IMO.
Look at this picture from ACG of an MBH headers install with cats. The primaries are tucked in close to the shielding. Those flanges on yours may need to be cut, and then the cats welded in.
Ahh so helpful . Those are secondaries right after the initial header tubes right? There's only secondaries I'm seeing. Ty for that. Apparently super sprint makes lth that fit with the oem 2ndaries. As much as I love the freeflow the odor makes it hard to enjoy when your lady friend is chocking on the fumes and not something else. I hope the aforementioned eBay listing I bought 2.5"(general oem diameter)" 200 cell won't impact my hp too much I'm also looking for some low end torque...
