v6 NA... the only place where people get into heated arguments about 4whp gains. the gain you'd get from 4whp is less than you'd get from:
1. running smaller diameter (lighter) wheels
2. driving without a passenger
3. running 93 vs 91 gas

the list goes on. Who cares? if you like the exhaust, get it. no one should care about 4whp in either direction.

on my car in above video, it sounds harsh... but that's because i have zero sound insulation... better to hear it from outside

can hear it better here at ~1:15 as I pass the car taking video

^^^

OMG

I have been calling the 370Z weak in terms of exhaust note!

NO longer

every one should be doing this if it's not your DD!

<------has 3" on 350z loves it

This link gives a quick summary of what I found with a 350Z on the dyno.
I did lots and lots of testing.

^ Very informative thank you for doing all that research :tup:

With non-res tp and the topspeed y pipe into a muffler that was pretty much a straight pipe was very loud. I think with HFC's you will be happy. It will be loud but shouldnt drone as much.

Btw, I had the Top Speed y pipe and Berk HFC's put on Friday to go with my Top Secret exhaust... My God this thing screams now! It does rattle the trunk a bit revving past 4-5k but it a much better response. Even stepping on it while cruising at 60 in 6 gear it accelerates. Before I had to downshift to 5. Im happy :)

and before anyone asks "how do u know if a 3" will lose power? have u tried it?"... well no i havent, but i understand how cars work...

Dont mean to sound like a jerk, but ur only partially correct. I made 330whp 270wtrq with my Amuse R1 Titan Extra. Swapped to Tomei Expreme Ti with same mods on car, made 330whp/270wtrq, same exact numbers. 270 peak trq @ 3000rpms and actually carries the trq curves higher and longer through the revs than the Amuse dual exhaust did. High revving cars dont want any back pressure, trq is measured on how fast exhaust gas leaves the cylinder, you want straight flow no back pressure or turbulence from flanges or bends. If anything, trq is sustained better through the revs and hp curve seemed to drop up top, but peak numbers were both same. Strange i know, EcuTek and DynoJet do not lie.

ZOMBIE THREAD!

Holy dead thread batman

Yeah, he comes in, drops some "knowledge" like the above, and disappears again. He should stay and play. We haven't had someone this aggressively stupid in a while.

:iagree:

I was warming up my popcorn expecting a show. :(

His post history says this:

Joined and made 1 post on 2013.

In February 2015, his car makes almost 400 ft lbs wheel torque and gps verified vmax at 175mph.

In October 2015, his car is the faster/fastest n/a 370z in Boston.

In this thread he claims 330whp and 270tq at some point.

His parents let him out of his timeout to play forza and use internet, and he got too excited. I forgive him
