Just got the Z's midpipe installed on my 05 6MT sedan. I was originally thinking coupe midpipe, but I spoke with Z Car Garage here in San Jose about it, and they do a custom fit Z midpipe. After talking to Rob at Z Car (nice guy) about which way to go, I decided to go with the Z midpipe.

Result: AMAZING improvement in the sound of the sedan - much deeper and "throatier" than stock, but not over the top. It definitely passes wife acceptance testing (an issue for me at least), and I can still drive a client around in it, but it sounds a LOT meaner.

By my calculations, a fair bit cheaper than the coupe midpipe to boot.

Thanks to Z Car Garage for steering me to this solution. Highly recommended.

What is the difference between the Z and Coupe mid-pipes? Pics?

The only difference would be length cuz it's shorter meaning you would have to use an adapter. Was the midpipe + adapter cheaper than jus coupe midpipe?

Whole thing installed was less than the $235 cost of the coupe midpipe on mynismo.com. Agreed that the Z midpipe is shorter than the coupe's, some welding surgery was performed to make it the right length. I've not seen the coupe midpipe so it may otherwise be identical, I dunno.

^^^WHS^^^
That is my understanding....
same only shorter & requires extension.

JMO,
But coupe pipe is still the best choice.
You can get a used coupe pipe for less than $100

either way then, very useful mod

Agreed...
Can't wait 'till I get mine bolted up

They're identical except for the fact that the G coupe middy will bolt right in without adding an extention. A 10% mark-up will get it for about $180.00 plus gaskets and about a half hour of your time to do it yourself...JBX

got any sound clips..

or maybe you can head out to our meet this friday..so we can hear it..

how much does the adapter cost? i think ill be able to get the z midpipe for free.

I made some sound clips of my 2003.5 Sedan with the stock midpipe vs. with the coupe midpipe. I also made pics comparing the size of the two. Posted this stuff at https://g35driver.com/forums/g35-sedan-v35-2003-06/47509-finally-got-my-midpipe-highly-recommended.html.

If you can find a used coupe midpipe, it's hard to beat the price. Mine cost me $50. Bolted right up without any hassles.
