will the helix DP fit with the stock catback?

 

not really..you might have to use a different bolts. how thick are the flange of helix dp anyway? if they are..yup gonna have to use a a longer bolts

 

It should mate up. Just have GB performance do it in Hayward. They'll make it fit for sure if anything. Talk to Gino.

 

I don't believe that DP uses the stock "donut" gasket, so I'm going to vote no.

 

No it will not fit perfectly.

 

Get a Turbo XS stealth back!!

Super

 

It will fit. I know because I had it on my car. However, the helix's tend to have leaks at the DP/CBE no matter what

 

my titek dp bolted directly to my stock exhaust.

 

I have the Helix catted DP & the stock cat back. I installed it and fits perfectly with no leaks. You use the gaskets & bolts supplied with the DP. No problems in 10K miles since I installed it. If it leaks, you did something wrong.

 

be careful before you decide to install the downpipe. you might get boost creep, and if that happens your screwed. I was fortunate to have an accessport with my titek downpipe and sure enough my car boost creeped, then loaded stage2 map and it runs awesome now.

 

i have TBE right now, the helix catless DP, and carbonti, and yesterday on the freeway i floor it, and my car went like POOM POOM, and my check engine light came on. =\ is that a boost creep? last time i had that, but the next morning the check engine light went back off, but this morning the light is still on =\

 

it felt like you hit fuel cut off right?? and the car kinda kicked hard.

thats boost creep. time to spend $700 for a accessport lol.

its really worth it !~

 

Will the Turbo XS 4" DP hit the a/c drain tube? Did you reuse the heatsheild? Did it bolt right up to the stock muffler? Is there any way you could post some pics? All or any more info would be awesome..Thanks

 

it fits, I ran it for over 6 months with no leaks.
