I'm running a borla hush cb with cobb ots stage 1 on my 06 sti. I want to get a bell mouth dp but there are so fn many. I don't know which one will mate up & if the o2 sensor will reach or not. I hear a lot about down pipes not fitting correctly & I'm trying to avoid any custom work. Or should i go with one brand tbe? Suggestions please.... Or a cobb tbe if anyones selling one.

 

I'm running a Titek catless DP w/ Stromung dual tip cb and everything mated up perfectly and o2 sensor reached easily. If you're going w/ catless, I don't think it matters much though. Good luck finding a DP

 

Will check it out thnx

 

Any DP should do. The borla has the sleeve in it that is adjustable for length as well as position.

I am running a helix catless and it works fine.

I am runnning a borla hush

 

I have had a helix, nvidia, & titek and all have fitted with no issues. I am running the borla hush too.

 

invidia ftw

 

Nice... Thnx for the input guys.

 

Do you know if you have the 2.5in or 3in adapter?

 

I have both 3in flat & donut adapters that came with the hush

 

I'M RUNNING HELIX V1 with the hush and its perfect no issues wut so ever.

 

Everything should be fine except Megan DPs IMHO mine did not fit right although different chassis. Also consider if you're ever going to get a wideband that it has the bung at the top also.

 

I run a Titek down pipe with Borla Hush cat back you just need the 3 in downpipe adapter
