Default Gut Ludespeed Cat

Was wondering if anybody gutted their cat in their Ludespeed downpipe?

I figured I would ask because I figured my cats are long gone anyways after running rich so I might as well.

I'm assuming the Ludespeed uppipe is catless correct?

there is no cat in the ludespeed downpipe.

that is a flex section. I have one sitting in front of me.

This would not be a catless setup however because unless you eliminated or replaced your stock cat pipe the ludespeed bolts up to it.

Some kits came with a high-flow cat on the downpipe, I know since mine had one. I put a flange on it, and now its catless.


Also, the kit does not have a cat in the upipe.

that is incorrect, you do not use the stock cat pipe with any of the turbo kits, header goes to uppipe, goes to turbo, goes to downpipe, goes to midpipe to muffler. you eliminate the cat section.

and yes, some downpipes came with, and some without cats. I would recommend cutting the pipe before the cat and welding on a new staright pipe, but to do that you'll either have to do it yourself, or take it to a less than law obiding muffler shop.

Thanks for the correction

in that case, I'd really try to find a local shady muffler shop that could just 'delete' that section

my cat gutted itself , tuning was not my strong point. i was running the stock muffler at the time and had no power at all. when i got my exhaust done we foung that it was cloged completly with the cat, and when i looked inside the cat, it was totaly cleaned out.


i might still have that map if you want to try that jk

hmm, i would imagine that is exactly what my cat looks like with my car running crazy rich, but I am trying to eliminate some things now with my hesitation and clogged cats supposedly can do it.

i found with my cloged muffler i would launch hard and then the power would just die, or on the fly it would put you in the seat when id punch it and then just die. i dont know if id concider that to be hesitation or not, is this similar to your problem?
