thats some awesome work right there :tup:

Custom sub-frame bracket
 

As a few already knows, about what my intent was with my custom exhaust. Its to have a single exit and I mentioned that I would have to make a bracket that would be similar to the 350z .

After some thought, I made something else that would do the same and less work. This will still allow me to have enough clearance for the straight thru muffler !

this is the final product, the baby blue is only what I could find a while ago ;(
Edit; the two outer nuts are only a spacer welded to the square tubing since I didn't had a shorter bolts there is the same threaded hole into the frame where the 350z bracket would go. then the 2 center one has an actual bolt welded with a slightly bigger nut also welded to act as a spacer.

Custom Sub-frame bracket had to be made for the future exhaust !

You see the idea behind this ? ;)

I wanted to do this and have it exit the fog light space in my Amuse bumper but I couldn't find someone to make a nice finisher for the exhaust.

Good job, looking forward to seeing the project finished.

very interesting.....
I would love to see the final product:tiphat: Innovation seems to running strong on this forum eY GaleForce :tup:

dats freaking awesome

The exhaust is almost done ! Pictures and video by this weekend !:)

Its very hard to not start he engine to just hear the noise until its finish. !

The exhaust bracket should be completed tomorrow !
Welding of the middle pipe & muffler on Thursday, my argon bottle is almost empty ;(

OMG,

you guys will love the noise coming out from my 3.5'' single exit exhaust !!!!

Video later on tonight or tomorrow.


On the bad news, while welding up the mid-pipe 6 of 8 welding tacks broke which mean I'm gonna have to add a 3-5deg bent somewhere this weekend and finishing up the last exhaust bracket.

then im gonna have to make a new tune !
its running a lot leaner now !
it was about 14.0-14.2 at idle now its around 15.0
then up to the mid/high 16 at cruising & slightly faster speed mostly where it was pretty much spot on at 14.7 until 2500-3000rpm
so the Y-Pipe combined with the header does seem to flow a lot more !

The video didn't turn out that great with the GoPro :shakes head:

but still sound awesome in real life !!!


It can be very loud at WOT and quiet at cruising speed.
On this video the mods the Z has are those ;
-Modified Momentum Header
-Custom Modular Y-Pipe (Currently 2x 2.5''resonator installed)
-Custom 3.5'' Mid-Pipe with 3.5'' Resonator
-3.5''In/Out Muffler

No CAI or some sort but only OEM intake since my previous custom one does not fit anymore due to some modification that was done.

Sounds good.:tup:

Plus your A/F ratio is very steady @ 12.4-12.5

Thanks

Yeah that was the first recorded pull after correcting the AFR.
it still need some tweaking from 2000-4500rpm
since it drop too fast into the 12.xx at like 2500-3000rpm


the last pull into the video is from 1500rpm to 7400rpm
Using the 4th gear with the 3.5FD diff @ WOT

That sounds real good! I can imagine what she sounds like from behind u:tup:

Sick. Always notice the DE/HR is so much more eager to rev than the VHR. I miss that. :(

Oooooooo :yum:
