Running stock s14 ex mani with a down pipe and high flow cat?

[s13pignose]

I was wondering if it will all bolt up? I believe stock s14 downpipe has studs coming from it that bolt onto the manifold, but I would assume all you need is bolts for the new one to put the two together.

I kinda got the answer I was looking for here...

But the cat I was thinking of running is the catco high flow cat that fr-sports sells

Would I run into any problems, I really didn't understand the whole floating flange thing.

Thanks for any help

ok so you want to know if you put a high flow cat in if you have any problems you should as long as its made for your car and the floating flange thing to my knowledge is to allow for an easier install and to make it work with custom setups but know you shouldn't have any problems ran a high flow on my stock ka for a long time till i upgraded to the sr

You don't need floating flanges unless you're using an SR downpipe with the KA manifold. That piece will line right up, but there are no studs on the OE downpipe, you'll use nuts/washers/bolts to mount that one in.

Yeah well I saw where you mentioned them in that thread, the floating flanges I mean. Plan is to keep the stock ex. manifold, bolt a 3" down pipe to that, and then hopefully the catco cat will bolt in behind it.

I saw on ebay they have downpipes for KA's, but maybe they just say that and they're really for sr's and ka-t?

There is one company that had some, flex pipe welded in, can't recall the name. Fitment sucked and the transmission bracket was welded on the wrong side.

i suggest you just weld it in flanges in exhaust always end up leaking
