The noise you're talking about..."pop pop", is more of a backfire. This is most common in the nonresonated setup, which IMO is just "pissed off" sounding! It doesn't happen every time, but on an occassion when you hold your rev in the higher RPMs and all of a sudden let off, you'll get a "POP!" Puts a smile on my face very time! :D

There isn't necessarilly an "advantage" to not having the mounting brackets, they just aren't required to have is all.

The RHFCs will cut down slightly, but not a ton. I personally have ran RHFCs on the G37 setup with 18" in the X, and currently run RHFCs with NONres X. Drone is more prone from the Xpipe then trying to stop is immediately out of the cat, but since you have 18" resonators in the X already, you would most likely notice an immediate difference w/ the RHFCs vs HFCs.

@1cleanZ - just want to say Thanks. Your YouTube videos helped me make my decision on no only FI for my CBE, but also NON-resonated. Love the note. Next mode will be FI RHFCs!

F.I. #1029 Due in 10/9 just in time for my 44th Wedding Aniversary. Son has the lift ready for the install.

Thanks. That is what I figured. Can this sound be adjusted (made louder or quiter) by tuning he car differently?

That will sound amazing. Lance [1cleanZ] is our premier product & sales vendor on the forum. Feel free to let him or myself know if you need anything. :tup:

Congrats! The wait will be well worth it.

I don't believe there is any way to adjust the sound level while tuning the car. If you'd like to give me a call, I'd be more than happy to discuss your question.

I was not referring to sound level of the exhaust, just the amount of backfire I guess. Might be a dumb question, maybe the level for the sound of the backfire and the level of sound of the exhaust are interrelated (directly or inversely).

I have no experience with engines larger then 4 cylinders and have never experienced backfire.

I don't think a phone call is necessary, I am not unhappy, just trying to learn stuff.

Thank you.

In case anyone wants a brand new exhaust without having to wait.

I'm glad you are happy; if you need anything please reach out. :tiphat:

Are you running Long Tube Headers or High Flow Cats?

Nope. Just 18" CF FI.

Would it be possible to get the list on the first post updated? :tiphat:

I love the scavagening (if that's a word). I've actually learned how to make it do it anytime I want: consistent throttle pressure to a real quick tiny, tiny, increase (100 rpm or so) and a quick let off. Sounds like a race car going into a turn.

I will get it updated within the next few days.

Thanks.

Thanks Tony! :tup:

888 is mine by the way.

Tomorrow's the big day!

#1021 will be installed. I hope I love it as much as everyone else loves theirs.
I did another mod recently that everyone on the forum loved....me....not so much. So I'm a little nervous.

What was the other mod, if you don't mind my asking?

Fast Intentions exhaust is here! (continued)
 

Cold start:

I was the one who called in yesterday wondering if there was a cobra in my exhaust. I'm getting used to the hiss, it's pretty interesting. Not bad, just different.

just wait until you pull into a non-Z type meet and everyone climbs under your car looking for turbos.

trust me. it happens to mine every weekend and even better when i leave the hood open. they ask what size turbos i have. its entertaining lol

that or with the striahgt pipes they think i now have done an engine swap.

Yea, I remember. I had the same sound on my car. I think it sounds awesome. :tup:

Hahaha... That's pretty funny. :bowrofl:

- Kevin

yea it literally happens every cars and coffee i attend. always someone laying under it or head buried under the hood looking to see if my intakes are charge pipes and looking for snails lol

the best part is even with lambos, ferraris, and porsches every where that i can still typically draw the largest crowd when leaving. all have their cameras out and videorolling lol they all love the FI staight pipes :stirthepot:

and yes they are Tony approved :tup:

Yes, they are Tony approved! Frank, when I get around to it, I may put your pipes into production. We will call them, "The FP" option.

-Tony

that would be awesome! i love it. my quest for more noise inspired a whole new option to the FI range :tup: :excited:

i would be honored :tiphat:

A legend in his own mind. :roflpuke2: :hello:

:iagree:

love you both too lol

these are the friends i keep :facepalm:

We love you too. :nutswinger: But don't expect long showers, reach arounds, and swapping split to happen any time soon.

Hiss? What hiss? I don't hear it. Please explain.

You don't get a hiss when coasting? Especially downhill? Seems to happen most as the engine holds the car back.

It sounds like more of a sucking sound than a leak. Although I've never heard it explained as to what it actually is.

The hiss could be harmonics in the exhaust from the VVL changing positions. Best guess.

When you go catless it hisses at the xpipe. I could make up all sorts of **** as to why, but I really have no clue.

I'll try to listen for it.

Love this Z community, I think its better than the G community!

IMO this is the best exhaust on the market for both sound and performance, plus the customer service and build quality is top notch. Tony recommended that I go with the 18" resonators since I also bought a set of ceramic coated LTH's and I couldn't be happier, heres a sound clip:

Thanks again Tony!:tup:

Sounds awesome! Excellent choice. I see a little bit of flames shooting off at the end of the video.

That was my favorite part.
