I just got these test pipes installed on my 04 6MT coupe this morning, car feels stronger, but I really couldn't open here up due to the rain in Socal.

I paid 110 for the pipes shipped, and paid another 80 bucks to install and fabricate a 2 brackets to prevent the pipes from hitting the heat shield.

I am running 285/30/20 in the rear and have no problem spinning the tires in 2nd gear at 4000 rpm in the rain. So definite power increase, very slight rasp, I am running stock exhaust. The only other mod I have is the JWT POP Charger and z tube.

Stock exhaust is slightly louder, but maintains the G35 throaty sound. Good bang for the buck, I think.

If anyone can host some video's for me, please PM Me.

 

Did you take any pics of the bracket they fabricated????

I tried to get mine installed this am....but the azz hat at Meineke wanted $125.00., so I said no thanks!

 

They are L brackets that attached to the factory catylic converter holder, it's like a Y shaped piece that holds / supports the cats. You'll see it when the car is on the hoist, it's pretty tricky to explain

 

I just installed these as well (after some misadventures =), the Megan Racing resonated test pipes. I installed them along with my UT y-pipe, and am very happy with the sound so far. There is no rasp, and a more pronounced growl when under throttle. While cruising and low RPMs there is not much of a difference. These pipes appear to be very well made and are a steal for $95.

Suprisingly I also did not notice any smells in the cabin as I was expecting. What comes out of the tail pipe is a bit more ripe, but can't detect anything inside the car. I would recommend using the gaskets that come with the test pipes, as they seem to be a bit softer and will form a better seal than if re-using the stock gaskets.

 

No drowning or humming noise inside the car? I saw the same item on ebay but was a bit hesitant on getting them.

 

The only annoyances I noticed were a couple slight vibrations, one on the right side at around 1.8k RPM, which I am almost positive is a result of me hacking up and over-bending the aluminum shield that sits above the cats, and another one coming from farther back around 1.3k RPM which I have not yet identified. I'm thinking the one farther back will either go away on it's own after breakin, or is due to the pipe diameter mismatch at the ypipe/bpipe flange which I will be fixing anyway.

I'll offer more feedback after it's had a chance to break in some more, and maybe an ECU reset. Unfortunately it looks like we're gonna get rain for a solid week

BTW - I am running with stock exhaust. My mods are: 3/8" plenum spacer, ztube, K&N, UT ypipe, MR reso test pipes

 

Cool let me know what happens before I purchase one.
