They came late to the party, i would like to hear drive by videos and i like to hear it paired with an uel header.

Before and after dyno numbers would be sweet.

Not really. This header is street legal in Japan and has the matching certificates for both ZC6 and ZN6 chassis. Export to the US was sort of an afterthought.

Drive-by depends greatly on the exhaust.

And not sure what you mean by "paired with an UEL header" since this entire header/OP/FP is one kit.

My bad, i want it except their headers. Very interested with the front pipe

This looks like a great setup! Looking forward to the results on this one!

Initial test:

Max db:
Front pipe only - 85.7db
Header + FP - 85.7db

Front pipe definitely is effective at maintaining same exhaust sounds. Exhaust testing next.

I tested 3 different exhaust systems to represent what people may buy on the market.
The Blitz VS/VSR is in the same realm as quiet exhausts from other companies like Invidia, TRD, Fujitsubo, etc. Large resonator and stock-like exhaust note.
The Tomei 60R represents the loudest exhaust available short of a straight pipe catback.
The Blitz F-Ti represents quality performance exhausts on the market but not at a sound level that induces popped ear drums.

All the measured sound is peak db.
The surprising part is that in all cases, this setup is more effective than the stock header/OP/FP in terms of sound suppression. As I suspected, combination(s) of resonator sizing is what is keeping sound levels tame.

For what it's worth, the current Apex'i/Blitz F-Ti setup is borderline Laguna Seca safe (95db @ 50').

Someone beat me to it! Very interested in what you'll find when testing.

Considering the full Apexi vs HKS. Just need some sound clips and then it's coming down to price between the two.

I like how the Apexi has an extra bung for doing wideband AFR

Time to start saving up for this setup. Thanks for all these reviews you put up on the forum and help on the previous thread i made.

I think this will sound great paired with the Fujitsubo Authorize R.

hmm O.o Damn.... Love it....& it would go prefect with my Apexi N1 X....

Don't think this is with tune too... so you can likely get more with a tune.

do they just sell the front pipe? I love it. HKS did the samething and paired it with their catted front pipe. Hope Apexi can sell it separately....
