LT Headers to Corsa X pipe
I have a Corsa Xtreme catback with the x pipe and i’m looking at getting longtube headers so I have a few questions
will I be able to just bolt it right up or will there be cutting/welding?
what will the cat situation look like? i’d like to keep my cats
Ive mainly been looking at speed engineering due to price, but would it be more worth it to go with something like ARH with their catted mid pipe, then sell my corsa x pipe?
Should I just go catless? it’s a daily
Please give me any pics and info you have relating to my situation.

Most header systems have an xpipe with cats to match and then bolt up to existing axle back. Probably better off doing that and then selling the corsa xpipe. And don’t go catless, it’s to loud and literally stinks.

I have MagnaFlow cat back and their X pipe. When I bought my Kook's headers they came with their X pipe and cats

i went with ARH LT and 𝕏 pipe with billy boat axel back ... my experience with ARH was horrendous, took 6 months to get them, welds look like ****, customer service sucked, for the price of ARH i was not happy and I ordered the headers without EGR and I got EGR. If I did it all over again Id go billy boat the whole way, their axel back was beautiful real craftsmenship and welds were amazing. you can tell they TIG welded their exhaust and ARH did a sloppy MIG. Billyboat also exceeded the original time frame. Rant over lol but yes id sell your corsa 𝕏 pipe and do the combo LT headers and 𝕏 pipe will make like easier IMO.

what companies besides arh and kooks do this? i’m not wanting to spend 2500+ on headers. would rather just get speed engineering and lost cats at that point.

Yeah. Everyplace has a weeks long wait and there is not much available used. I have
been on the hunt for a 1 7/8 set and X without cats. ARH or Kooks ideally but they are built to order now and weeks out.
I will look into Billyboat.

I have LG 1 3/4 header, not sure if LG sells these anymore, also have cats, Billy boat bullets, I’m the original owner of my 2004, almost 90k miles on it and have had the vehicle like this since 2005-2006, never had a problem with anything, 20+ years, I’d say the quality has held up.

I disagree because he mentioned speed engineering. If you go that route you could use the LT headers and keep your corsa x pipe. I did this with my Borla X pipe and Stingers. I used the 3 to 2.5 inch pipe reducer that came with the kit to bolt to my x pipe. I didn't use the speed engineering x pipe because the Borla x pipe and axle back have a nice flange set up and I wanted to keep that. I also went catless, yes its loud but not insanely loud and it doesn't smell after it was tuned. I recently swapped cams again and need a retune so presently it does smell (running too rich) but I hope to tune that out again.

yea i’m in an odd situation, I wasn’t planning on doing headers for a while so I just went with corsa exhaust and x pipe. but then my coworker got long tubes on his and it sounds so good and I wanna do it now lol. he’s catless and I hate the smell but it does have a nice sound. if I can get the smell tuned out I will definitely go with something like speed engineering. my coworker is running kooks long tubes to corsa x pipe and mufflers

You can’t get that smell out. Catalytic converters have a purpose, and so do high Flo cats. We will put you in the back of the line on every club trip if you remove the cats. The person behind you will not want to smell that on a 650 mile trip to bowling green. My neighbor removed the cats on his supercharged camaro, the tuner said he will tune it so it doesn’t stink, guess what, it stinks. Now my neighbor wants high Flo cats.
These are just suggestions, you do what you want.

Respectfully, I don't drive my car to be apart of clubs and do trips. It's just a daily, I take it to car shows occasionally. I don't mind the smell, but it would just be nice to have it be not so potent.
