Coupe midpipe is the best mod! It makes the tone much deeper and have a nice grow all through the rev range and when you're cruising and let off the gas it gives you a nice burble. I picked one up on here for $100 and had it put on for $150 but it's a really easy job that can be done at home.

This is mine stock
And this is with the midpipe

 

Sounds nice.

Nice.. sounds crazy without a muffler! Lol I like how you took all the badges off. Thinking of doing that myself.

 

just dont take off the mt fuji (infiniti emblem) there are 2 holes behind that. just so you know.

 

Hey, thought I'd jump in here too as I just purchased my 2005 G35 yesterday. Nicest car I've bought so far in my life, and quite like it. The previous owner did some nice cosmetic touches to it. Not sure how many mods I'll do, maybe the some of the most recommended engine mods like the spacer/ztube, possibly exhaust. Car is for my wife and I to share (I DD a motorcycle), so probably won't get too crazy with it. Thought about coupe springs, but she rides kinda stiff as it is, so might not mess with it.

First neg: just noticed it has the notorious rear axle clicking (checked around the forum). Didn't hear it when I was test driving, cause the windows were up/AC blasting. Don't know how long it was going on, but seems like easy fix. Does anyone know if that clicking can lead to more serious problems if left uncorrected.

Otherwise, awesome car. Can't wait to take it out and give it a good drive.

 

Looks nice.
