i know that you can buy a flange for it but i was wondering what downpipes can hook straight up to the hush?
so far ive only seen the hks. im planning on doing stg 2 cobb soon too so ill get an uppipe also.

 

Hey nerdy,

Im looking to do the exact same thing... How much is it running you to get all the stuff? Have you found any other downpipes that will hook up to the Borla Hush? I wanted to get perrin... but I dont wanna have to go through all that work if i can solve it by getting something else....

peace ty

 

I'm using the cat-ed Cobb downpipe (Nice piece!) with Borla hush catback and AP with stage II, 93 octane tune. The downpipe and catback fit right together. Yah, they neck down to 2.5 in. at the inteface, but the flow restriction is minimal over such a short length.

I figure why not get the downpipe that Cobb tuned with. They don't claim much improvement from a catless up-pipe and it's pretty important for startup emissions, so I elected to leave the stocker in.

I also installed Kartboy hangers and a Cusco heatshield at the same time. I'm very pleased with the performance.

 

Huge difference between catless up-pipe and a catted one. Especially the stock up-pipe. Best mod to relieve turbo lag. Definately a noticable difference.
