Cutting Apexi DP

[heavypedalmuzic]

after measuring my Apexi Gt DP, the inlet diameter is approx. 2.25" and outlet is approx. 2.7". its certainly not a 3" DP. with a 2.5" tubular o2 housing on the way i definitely dont want to go 2.5 to 2.25.
has any one cut off the 2.25" piping and welded a 2.5" one on?
if so where do u cut it, before or after the flex section

(if its cut after the flex section then i'll also need a 2.5" flex section along with the piping)

Thanx for the feed back

We just ordered the N-1 and it supposedly starts at 2.5" until the first bend, then it starts to taper out toward the muffler, ending in 3.3". I know that APEX'i N-1 mufflers are 3", so I dunno. I was under the impression that the GT series was pretty much the N-1 with stainless piping.

I just went through the same crap of having to get the necked down part hacked off, I took it to a muffler shop and they fixed it up for $40 bucks.

the Gt is the ss version of the n1 and they say its 2.5" for the first ft or so but my measurements show about 2.3"..im only going by what i see.
