Apex'i N1 Downpipe question

[BOOSTIN21]

hey i am looking to buy the N1 Downpipe from Apex'i it says it is a downpipe and catalytic converter replacement front pipe and i was planning on buying a test pipe but if i get the Apex'i downpipe does that mean i just need to buy a cat back and that will bolt up to the downpipe or what? I was planning on buying an ATR 3" Catback will that bolt up with out a problem to the Apex'i downpipe. let me know, thanks

I'm looking to buy same apexi n1 but i don't know how many inches should the inlet be. Anyone has any ideas?

 

[BOOSTIN21]

what do you mean inlet

 

[Drifter00]

Yes the DP extends to replace the cat and bolts directly up to the catback exhaust. Whether it bolts up directly to the ATR, I'm not sure. As far as what the 2nd post asked about for the inlet, i'm not sure what you mean.

 

[BOOSTIN21]

thanks alot drifter i'm pretty sure that the exhausts will bolt up

 

[drk mrk iv]

I hope it bolts up to stock exhaust location. I have the downpipe sitting in my room. :laugh:

 

[blcknspo0ln]

the DP will bolt to the stock cat via the adaptor that comes with it..

 

[BOOSTIN21]

its a cat replacemant DP

Same DP i have. It bolts right up the the o2 housing, replaces the cat, and bolts right up to my catback. It fit like a charm.

yeah i thought that the DP replaces the cat. and that it should just bolt on to your N1. . my N1 went right up to my cat. soo am thinking the Dp will meet up with it as soon as i get it.. . . . .how much of a difference did u guys feel. .i felt it a little more in 3rd and 4th

Won't you get boost creep?

 

[Drifter00]

Why would he get boost creep?

 

[B00STED4banger]

when i put my n-1 dp on i suffered from boost creep on my 14b and my big16g, but now i'm boostcreep free on my 50trim. And i had a ported 16g with a ported evoIII o2 housing

Won't you get boost creep?

Yes, on a 1g you will almost definitely get boost creep

 

[blcknspo0ln]

3" o2 back = boost creep. at the very least get a ported 2g o2 in there...

 

[BOOSTIN21]

on almost any turbo with a wastegate flapper smaller than a 34mm will get boost creep
and as far as getting a ported 2g o2 housing i am getting a ported EVO III o2 housing that should do the trick and then some
