GT350 Kooks long tubes and factory axle back

[nastang87xx]

UPDATED WITH DYNO VIDEO & CHART:


[igm]p/BASoZsYtjHk[/igm]

Bone Stock the car made 466.72 HP / 390.19 TQ
With Kooks Headers, Catted X-Pipe and OEM Mufflers it made 481.86 HP / 406.66 TQ
With Full Kooks Exhaust it made 491.02 HP / 410.01 TQ

There have been no other mods made to the car. The tune is still bone stock. I am very impressed with the gains and I know the car will pick up more from just a tune. I hope to get it tuned next week before the 1/2 mile race in Ocala, FL.

I'm guessing that video quality has something to do with my lack of enthusiasm.

So far, I'm still good with just having a resonator delete done.

Im VERY curious to hear what an H-pipe mod sounds like. These cars come with an X pipe and to me is too droney. Really want to hear what an H setup would sound like.

You can definitely hear more of the FPC sound with that setup. I like it!

I don't think there's an improvement that can be made over the stock exhaust. Remove the resonators from the non-R models might be all.

Are these one and the same?

At WOT, you can tell that the sound has changed to a more Ferrari-like note. I bet the flow was optimized quite a bit, and I hope the power gains show that to be true.

From the video it sounds strange. Sounds higher pitch like someone took a Ferrari exhaust and added distortion to it
Not angry sounding but does sound racey. I would imagine it being better in person. Usually cell phones videos don't record high pitch very well.

Yessir.

Yeah, that sounds really weird once he takes off. Almost has a vacuum cleaner like quality to it.

I'm still giving Lethal's mid-pipe a shot. If I don't like it, it's a heck of a lot easier to undo than headers.

Definitely less raspy and higher pitched compared to stock, really hear the motor screaming

I like it.

Exotic!

Sounds like angry bees

I'll in the same boat. But I'm definitely doing a resonator delete. I have a feeling the cat delete pipes with the resonator delete are going to be entirely too much to bare though. I can't imagine it not being idiotically loud.

I like it. Put it on the list.

Idk what it is but it seems off. if it was on any car but a mustang I'd like it but it really doesn't go with the mustang. idk how to explain it but it doesn't sounds right from the video. may be better in person.
