ok i have the helix catted downpipe and the bosal cat back. when i put it on i noticed a couple of leaks. then i noticed that the downpipe is hitting somepeice of metal right before it connects to the cat back.


now i fixed 1 of the leaks and spent all day today trying to fix the second leak. i tried different hardware i tried using two gaskets but nothing is working if anything i mad it worse. what is leaking now is where it connects to the downpipe ontop of the flange there is a gap that i cant close it is like the donwpipe has a little bit of an upgrade so only the bottom gets a really good tight conection. what do i do. someone help my dumbass

 

is this a new or used helix downpipe?

 

it was used on an 07 sti he took it off the car the day i got it

 

Disconnect the axel back and try to connect the midpipe to the downpipe. It should align a bit better. I had to cut one side of my stock hangers to make my pipes fit without leaks.

 

what do you mean you had to cut one side of your stock hanger to make it fit w/ out leaks

 

Those rubber hangers I cut one side so it hangs lower and easier to move. I had to do this because I bought extended hangers for the axel back but forgot about the mid pipe.

 

im going to get extended hangers im just not sure if hangers are the problem. it would be so much easier if i had a lift

 

where the white line is the exhaust leak is the arrow just means its it goes around almost to the other bolt

 

You should realign your exhaust agian. Don't double gasket your just wasting your money, and it will still leak.

 

i did that today still not working i put my stock exhaust back on im done f@#$ing with it

 

Exhaust doesn't look lined up at all. I ditched the spring bolts also.

 

hehe, is this the one I saw posted for sale? Take it to DB, and see if they can take a look at it...

 

its not the downpipe its the catback thats not right. i have used this downpipe with a different exhaust and it worked perfect. just doesnt sit right with the bosal. plus i have a catless in the garage that im goin to use. screw catted i love catless

 

go to db and have him install the cbe if u are having trouble.. he will fix it.. i will be there tomorrow too!
