anyone help me?

Im trying to install a cat back exhaust system in my legacy GT 2005 but the midpipe isnt going onto the stock dp because of a lip that is on the stock dp. this seems to be the next big step to get over and its really irritating. if anyone could help that would be awesome.

 

pictures? and what kind of exhaust are you trying to put on?

 

i dont have pictures and dont have time really right now to do it but im putting a Gimmick Motorsports cat back on my legacy and im pretty sure the gap between the stock dp and cat back is supposed to be there?

 

are u installing just the mide pipe or the whole cat back

 

i put that one on my lgt but i had a invid. dp im trying to think of the gap did u go with a 3inch? if so do u have the adaptor(do u need) so u can hook up a stock dp to a catback?
where are u in the south meto ?

 

the mid pipe right now then im getting the rest of the catback on after i get that pipe on

 

i dont have the adapter because i didnt think i would need it necessarily i have a 3 inch catback and i have a 3 inch cattless megan DP but im waiting to install that till i get a tune, i thought the catback would be a simple bolt onn

 

it should be a simple bolt on
trying to think of the lip on the stock dp

 

there is a lip that went into the stock catback, and for some reason the 3 inch wont fit all the way over it ( im not sure if it is supposed to or not) i just want this thing on

 

im in rosemount btw i didnt see that question

 

i do reme,ber with mine i found it easyer if i droped the dp off the hanger that was under the car and i had to do the top bolt first to get a good seal with no leaks

 

are u sure that they are both using the same flange. ones not using flat and the other using donught

 

without pictures all I can think of is you might need this http://www.importimageracing.com/p/3-Inch-Downpipe-Adapter-02-09-WRx-STi.html

but I don't have a legacy so I am not familiar with your setup at all

 

its in and runnin very beautifully thanks for the help guys

 

how did you fix it?

 

i found out that im dumb and the "lip" was a doughnut gasket so we just got some longer bolts, got it snug and put the rest on. no leaks sounds great. dp going on soon!

 

make sure u get a downpipe with donught style or it will start leaking soon. ask me how i know.

 

think itll matter if the catback wasnt set up for a doughnut gasket? it was set up for a flat gasket that it came with. i just figured it would be easier to use longer bolts to snug it up to the gasket then when i switch the downpipe just use the flat gasket on it

 

it will blow out the gaskets i went through 3 gaskets in about 3 months before i welded on a flat flange 2 my downpipe

 

you sure you just didnt over tighten the bolts?
