2001 Yukon Y-pipe options

[bill9000]

Hi, I have a 2001 Yukon all stock, except a welded in Flowmaster Super 44 in place of factory muffler.

I believe my cats are plugged and want to replace the y-pipe. But I don't want to put headers on this...
I have found this item which appears to be a direct fit:

but I was wondering if anyone knows of any catless options that are also a direct OE bolt in?

Thanks!

Does the Flowmaster sound good? Trying to figure out what exhaust I'm going to put on mine. Debating a Carven

The Flowmaster sounds really good, nice deep tone. I personally like extra extra loud. And it does sound real nice... but if I am having to replace y-pipe then I'd prefer catless as it'll be louder with the same deep tone.

But to answer, yes it's very healthy and good sounding.

Well if you are going to delete cats then might as well just take it to a respectable exhaust shop (that will delete the cats) and just have them fab up their own catless y-pipe. Might even be better (and louder) if you go for a catless h-pipe

Yeah, all the shops around here won't do it though.

Oh ok. Then yeah I'm sure some aftermarket exhaust company has one

I’m pretty sure all the off-road y pipes are for headers. You’ll have to find someone who will cut your cats out and replace them with pipe. Tell them it’s for an off road truck you’re building. Obviously you’ll need to bring just the y pipe by itself.

I thought Summit sold a catless Y for the 800s, maybe it was for the 400s.

Did you ever end up doing anything with your truck?

I have a broken honeycomb in my cat so I’m going to take it to the exhaust shop today to have them straight pipe both cats.

I’m thinking while I’m there and changing the exhaust to maybe customize the rest of the exhaust.

I’m considering having them make me a custom dual exhaust with the single flowmaster 40 series. 3in piping. Right now everything is stock. Anybody know what the outcome of this will be if I do that? It will be similar to this already made flowmaster system

Or I’m not sure if I should just have the cats removed for now and keep everything else stock
