up and down pipe question

hi all
does my hawk have a cat in the up pipe ?
can I get a decat pipe replacement for the downpipe cat and still keep the main cat?
I want to make the exhaust a tad quieter by leaving the main cat on as it has a hell of a drone on the motorway.
I am running a 3 inch turbo back catless at the min,
I am hoping also if I refit the main cat it will solve my overboost problem at high speed lol.

Get a quieter cat back system and a decent remap, would sort your drone/overboost problems.

As for Cat in the up pipe, if it's an sti, no, if it's a wrx, I would think so, just not certain.

Thanks for the reply mate . I have a blowing noise from the front end and was thinking about a new up pipe ? As I can't find any exhaust blows from the turbo back over ?

Yes there's a cat in a wrx up pipe

Daz is it worth replacing the up pipe with a decat ?

If you want more power you will have to

are all the up pipes the same ie classic,bug,blob and hawk ?

not sure on that one,an sti up pipe is easy to get

Get Alan as performance to flow match to your turbo

Anyone know if the up and down pipes are all the same for new age and Hawks ?

Yes they will be id just get a hawk sti up pipe

will this pipe be ok to bolt my original cat to ?

with there being 2 cats in the down pipe , which is classed as the main cat ?

Not sure but they are really restrict the flow... Forget eBay speak to Alan at as performance he's good with this stuff and will sort you out and explain all

thanks Byers,
