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:

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.

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.
