F.I EXHAUST + GTM RESONATED TEST PIPES = Pure sexiness

Today, I installed the GTM resonated test pipes @ the amplified motorsport.
Apparently, this mod is not for everyone.
And, I decided to write a short review since I didn't see any review for the GTM test pipes.

The reason I went with the GTM resonated test pipes was becaues of the extended O2 sensor mounting(J-tube) in order to prevent the CEL.
I really didn't get any sign of CEL at all even after flooring so many times. Because of this, I didn't even worry anythin about the CEL.
But, I will keep watching.

I know F.I also started making the similar stuff,
but when I realized that, I had already ordered the GTM.

My first thought was that it were a little raspy,
but I after I drove 300 miles, it sounds exactly like F.I exhaust but a lot louder. No raspy and i don't feel any annoying drone but A LOT LOUDER exhaust note!

I warn you that you will get lots of unwanted attentions. I have to put into neutral several time not to attract some police officers on the way back home.

When it comes to a butt dyno, I do really feel more pulls.
I really can tell there is an increase in TQ after 3k rpm.

But, a butt dyno isn't so reliable, so that's all i would say.
The GTM claimed +12.3 HP and +10.6 TQ with a dyno(Stock exhaust but test pipes).

Overally, I'm 98% happy with the GTM test pipes. (-2% for unwanted attentions)
Also i want to say thank you to the amplified motorsports for getting me a good deal on this.
It was completely worth driving 2 hours for me.

To be honest, it smells pretty bad right behind the exhaust when I park in the garage,
but I don't smell when i'm driving. For outside, you don't smell that much because of winds and other cars even if you are standing behind.

the driver will smell a hint of gas smell if standing at a red light more than 30 sec because you know what you have under your car. But other pessengers don't even notice anything. When I was saying driving outside, I meant stop and go traffic because nobody really smells anything on freeway.


I assume you are worried about being followed by a cop?
I will avoid stopping at a signal with a motorcycle police because they can smell it right behind the exhaust even though it's still hard to tell because of wind and other vehicles. Mostly they will think its from damn disel trucks that just pass by.

Yea, I really like the test pipes, just worried about cops behind me.


Solismo, do you feel a difference between the test pipe and the HFCs?

I laughed so hard

I let one friend drive my car and drove his car following my car,
I didn't smell anything while driving and stopping at a light.

But when i rolled down the windows, I had to roll up again.
Though the smell isn't that bad, I was worried any health issue.
