sweet i cant wait till i hear the sound clip cause im looking to do the exact same thing

 

put an '05 coupe midpipe on my '06 sedan for weight savings and I love the sound. Its a noticeable difference in tone but still soudns stock until you open it up. I already had a Z-tube on it so I don't know if that had much effect. Do it!

 

If you want to add more exhaust volume using OEM parts on an 05/06 sedan, this is what you do:

1) 03/04 muffler. It's about 10% smaller in size and will be louder than the 05/06 muffler.

2) HR Y-pipe.

My 03/04 sedan has the 05/06 sedan midpipe, OEM muffler, and HR Y-pipe. The car is louder than a stock 350z/coupe. I love it.

 

^ Number 1 is really great for for people that have an 03/04, but if you have an 05/06 imo just save up for an HKS :P

 

HKS was too loud for me with the CM and HR y pipe. I know, I'm old. I've been looking for an 03-04 muffler for almost a year to put on my 05.

Stock rocks! (DaveB and I might be the only people on this board to say so )

 

^ really good to know, I thought the HKS was not that loud.

Any how, have you checked junk yards and such?

 

Yep with no luck.

The drone with the CM became too much. As far as exhausts go it was pretty tame. Just a little too much for me. I realized wanted a stealth approach. Quiet but quick. I also realized I bought the G because of the smooth ride and luxury,

Been there done that with the louder cars.

 

^old fart

I love my HR y-pipe, coupe mid, and HKS lol at times i wish it was louder lol Nothing like getting a rev match in a tunnel and just nailing the gas. The noise gives me goose bumps

 

I don't really have a problem with the drone

 

The HR Y-pipe will fit just fine on an AWD. I've got one on my 05x. I'm happy with the Sedan middy and the HR Y, but I definitely want to put an HKS on it. It's just the sweetest sound.

The first one is donpisto, a member here, with what is I think a stock 06 with the HKS. The last one says it's got a Coupe middy along with the HKS. Enjoy.

 

For a nice, less subtle sound, yes. For performance, no.

And yea, it sounds much better with an HKS axleback

 

HKS axle-back ftw

 

Wow...really? Never heard that before. Must mostly have to do with the HR Y-pipe, as the OEM muffler isn't loud at all. Wish I could hear that setup. I have the UT Y-pipe, which gives me some burble when downshifting. Curious to see what the HR Y-pipe looks like now....

 

Here's the 05/06 midpipe without HR y-pipe and just the OEM muffler (part throttle). With the HR y-pipe, the volume is increased another 10%.


Here's the 05/06 midpipe and HR y-pipe from outside the car (cold pipes, part throttle):


Here's the 05/06 midpipe and HR y-pipe from inside the car (full throttle):


I've also had the coupe midpipe and the 05/06 midpipe has a far cleaner and deeper sound and absolutely no drone.

 

i dont have the coupe mid pipe but just no midpipe at all there is no drone no rasp and its not loud at all just a slight hint of exhaust note. just ordered hks rear we will see how loud it is but i had a all motor honda forever and hated how loud it was truley love the setup as is now
