i want to get a borla hush for my 05 WRX Wagon. the car is bone stock no mods other than the grounding mod done to it.

My question is has anyone put their car on a dyno before and after adding the Borla on to their ride. how much HP did the Borla actually get you????

 

good choice

 

I would guess about 0-4whp on a dyno. I might be a little optimistic though. You won't see much if any performance out of any 3" catback on a stock wrx.

 

ok so i've got about $600 to play with what would you guys suggest i get a cobb access port or a borla hush. keeping in mind that my car is bone stock

 

sorry to revive this old thread but i searched and this is basically what i had a question about, the 06's uppipe is catless so im keeping that, i was wondering if i get a helix catless downpipe will it fit perfectly with the borla hush? also im waitin for the next gen AP, should i wait to install the dp and catback?

 

Hey man... Im also in south OC... and personally wouldnt recommend catless as the gains between a high flow and no cat are miniscule... like 1-3hp... Especially since youre going with the Hush... The catted Helix itself exhibits a pretty snarly rumble even mated against the hush... Id go catted.

What you need with the borla hush is a flat-flange adaptor... to mate up to the helix... Size-wise, they will fit, you just need the adaptor...

Some vendors sell the hush with it, some dont... check around.

Goodluck!

 

what is the next gen ap?

 

next gen ap is a cobb accesport version 2. it has some new cool features, but does the same performance wise as the first accesport. go to cobbtuning.com for info. this in my opinion should be the first mod done to a wrx

 

installing the downpipe isnt too bad...I went with invidia cattless...

 

Pardon my newbness but will a DP make you fail smog?? I know TBEs are illegal but DP aren't right??

 

Anytime you alter the smog equipment it's illegal. Because the downpipe has a cat on it, if you remove it, you've altered the smog equipment. I they don't notice and you pass smog, consider yourself lucky.
