Recently swapped the midpipe off of my sedan for a G35 coupe midpipe. Took a pic of the two so those interested could see the difference (when I searched I didnt see any comparo pics so wanted to share).

The sedan mippipe is off of my 2004 G35X sedan, the coupe midpipe is off of a 2005-2006 G35 coupe. You can see the huge difference between the two, sedan midpipe is quite a bit heavier obviously. In terms of sound, huge upgrade imo. Really like the nice deep tone my exhaust has now, much "sportier". All other exhaust components are the same (stock), all I changed was the midpipe. Fit was great, direct swap and just needed to tweak a heatshield a bit so it didn't rub on the coupe midpipe.

 

wow! Can't wait to get mine.

 

How long is the coupe midpipe?

 

Yea i remember when i picked up the sedan midpipe a year ago when i took it off lol...i was tripping out, then the guy asks "do you wanna keep it" i said hell no, burn it lol

 

Coupes have the Calsonic resonator that sound much better.

neo_anderson - fitment is exactly the same if you get the mid-pipe off of a G coupe. Z mid-pipes have the same Calsonic resonator, only the piping will be 4" shorter.

 

05-06 had a different midpipe vs an 03-04 fyi

 

Coupe mid-pipe and HKS axleback was a popular mod before sedans had better options available. Stillen was popular too, but just cost more than many sedan drivers wanted to spend, and sounds different too.

 

I know that. I just need the size b.c when I get it I have to use my car to get it. I only have the back seat hole to fit it in the car. I want to get an idea of how it will look in the car, since its an hour ride.

 

I used my car as well, the ski pass thru worked fine when I picked it up. no problems.

 

Guy told me it was off an 05-06 but I have no way to confirm. Came off a wrecked G coupe. So really I have no idea what it came off of, but it fit and it sounds good!

 

All I neeeded to know. Thanks.

 

He was actually talking about the 05-06 sedans. They are actually a little smaller than the 04 sedan mid pipe. Some people would prefer to use the 05-06 sedan midpipe on the 04.

With the coupe mid pipe I got some slight droning crushing around 45mph, but once I got the hr y pipe the droning was gone.

 

Ah got it, thanks. Haven't noticed much droning so far with my setup. But from what I've read on here before, I believe the y pipe is a little different on the X mode ? (vs the standard G35 sedan).

Either way, I'm pretty happy with the mod. Cheap and easy w/ improvement to sound and maybe some slight power gains (shed a few lbs too not that it matters much). Probably stick with this setup for a while (also recently installed a Stillen intake and z tube as well as a 5/16 motordyne spacer). Have an Eiback rear sway bar, Tein H-tech springs, and 19 inch G37S coupe wheels that all need to still go on the car.

 

I considered the Stillen Gen 2 exhaust, but came down too not wanting to spend a grand on it, just too much considering how much I paid for the car (I bought it off my Dad for cheap to use as a daily driver). For $80, the midpipe was worth a shot and I'm very pleased with the end result. Driving around the car sounds totally stock, not loud at all. But when I step on it, it sounds like a completely different car with the coupe midpipe and the other mods I did (stillen intake, ztube, 5/16 spacer).

 

i have a 05 coupe middy, I wire brushed it after spraying it with some break cleaner, came out great ! after that used high temp paint and sprayed her black so it would prevent any rust . . . obviously it doesnt matter how it looks but as far as conditioning, its mint. I'm just waiting on my muffler and im going to install both in one shot.
