Not sure that the 2007 G35 sedan has the Y-Pipe we are looking for. I checked it out at the dealership last time I was there and the Y-pipe didn't look like the same shape.

 

AARONHL - I added the G37 to the list based on the post quoted above.

Ricog35x - are you 100% certain that your y pipe is from a g37?

 

I said 2007 G35 sedan, go the the dealership and look underneath one.

 

Let me DOUBLE check with my service guy.. I'm going in for a 4 wheel alignment later this week.. so I'll have him pull up the work order for this install and see EXACTLY what p/n they used...

I looks JUST like the big dog that DaveB had in his side by side shot comparing the old funky OEM pipe with the Z pipe he used.. WITH the exception of NOT having hockey pucks or even the brackets for them.. just clean pipes to the collector.

 

is the revup y-pipe the same as the hr y-pipe?

 

Nope. The Revup uses the old style y-pipe. It has to come from the HR motors.

 

Well, I've figured out the purpose of the rubber/metal pucks. Once temps dipped below the 30s, I felt some rather significant vibration thru the seat when the car was cold. This only lasted about 2 minutes or so. I put the pucks back on and nearly all the vibration was reduced. Clearly these were designed to quell some odd vibrations the HR y-pipe creates when the motor/exhaust are cold. Once the car is warmed, pucks or not, the vibration is gone.

 

im still looking for a hr y pipe anyone know anyone selling one? some dude on my350z had one but he wanted WAYY to much he asking like 300 for it.

 

if you dont find one, just get a used aftermarket one man, like nismo, megan, stillen, or somethin like that

 

No, go with the HR only.

 

yeah thats what im thinking about doing if i dont find a HR.

 

I'd have to agree. OEM fitment, OEM R&D, OEM quality, heavier gauge metal to keep heat in and exhaust velocity up, insulated to keep noise down, and most importantly, big flex sections to take the load off the exhaust and keep NVH down.

Also, I haven't read anything about people adding aftermarket y-pipes and seeing the type of "perceived" gains and improvements in drivability. What I've read about aftermarket y-pipes is rasp, increased NVH, and a low rpm power loss. I for one haven't felt any sort of loss and IMO, the driveability has improved in the low to midrange. I'd be the first one to tell you guys if I felt any sort of power loss or a negative impact on driveability. IMO, the HR y-pipe and Revup airbox have resulted in much improved drivability. Far more than I ever felt with the MD 5/16" spacer which is still a great mod.

 

I'd sell mine if I could get someone to give me their y-pipe + $$$

 

how much are you talking?
