Are LT headers worth it with FI

[Superman112]

Hopefully this hasn’t already been discussed, so what does everyone think? LT’s worth it? Will have the VMP Loki kit installed in a bout a month or so and am deciding if I should just go with the headers when the SC gets installed? I’m not trying to go crazy hp numbers and I don’t hit the track. Just not sure if the extra $$$ is worth it. I’m looking at TSP headers or SW no carted ones. Any info is much appreciated.

I don't know about what kind of performance gains LTHs bring to supercharged setup, but if you are looking for NON catalytic ones, you'll have to buy a used set. A lot of manufacturers and major retailers have stopped selling them.

Yeah I know that sucks, unless I have a shop custom make me a catless x pipe or something I think the SW headers come without cats but looks like they may not line up with the borla mufflers that came with my car when I got it.

Long tubes definitely worth it, even more on boost. And a good shop can fab a connection if something doesn't line up in your exhaust.

Though not sure what the muffler has to do with the header connection, opposite sides of the exhaust unless you have some sort of mid mounted muffler.

probably 40-80hp with FI. Totally worth it...

Catless LT vs catless stock header is not going to make enough difference to feel maybe 30-40hp. Everyone compares catless LT to stock headers with the cats. Now that might be up to 80hp but not catless to catless.
Buy a set on eBay for $200 and get the exact same power gain as a $1000 set. The quality will not be as good sure but the engine doesn’t care. Same power 1/5 the price. eBay headers and wrap =$250
No matter where you get them I would get them fast because you just don’t know what is going to happen

Maybe I miss read. Are you really saying long tubes vs cat delete is 30-40 hp??? I honestly haven’t seen anyone post more than 10 hp difference between the 2.
No doubt long tubes makes more though.

with forced induction it will make more power with less work. Catted vs catless is mostly sound but I believe 5-10hp difference. As for doing just a cat delete, the kit is kinda pricey and for me I spent not much more and went stainless power LTH. Just depends what your plans are with it in the longrun I suppose.
