Installed new GHL exhaust today.
"Woohoo" I like it! It is much lighter than stock. Tho I didn't weigh it, the parts mgr. did and claimed it was 22.5lbs. lighter than stock setup. I hoisted the muffler/tip assy. and it is LIGHT! Nicely finished w/polished stainless. I have a dyno print out in front of me and it does indeed give a whopping 18hp/10tq down low and that is exactly where I needed it when I lost 3/10 sec. by going from 17" 235 to 18" 275 rears. I was/am very dissappointed over that huge loss, but this 18/10 addition will help. Already my bd tells me there are some nice things going on now with the GHL being "learned" by the ECU after the first 100 miles or so. Next week the 6MT differential (3.54) will be installed in Atlanta in place of the higher 3.35 auto rear and I think I will be back to high 13's/low 14's in my auto. I also had a good conversation with the folks at RMRacing (they mfg. CAI for a lot of cars) and they maintain that the stock intake is optimal on the 350 and recommended I not go with one from them or any other aftermarket CAI's. They did however, suggest I change the stock air filter to a TrueFlow 3 stage filter, which I did. Overall, I am enthusiastic with the response I have gotten from these two mods. Regards, Jim

Re: Please post pics!!!
Moodie, Fit and finish look very, very good to me. The exhaust is a Y-back and also does away w/pre-silencer. My local Nissan dealership is the only one selling it in the Phoenix area and it goes for $1,250, BUT it is $995 to MY350Z.com members. It was $80 to install.
It is louder than stock when pressed. It is deeper and more guttural than other after market systems I have heard. It is a VERY authoritive and distinctive note. Yet, it just purrs when normal throttle is applied. It p/u the exhaust pulses more than I have ever heard before from other exhausts and that is a very heady sound that I really like. I find myself rolling down the window when I am beside a wall or between bldgs. just to hear that staccato bouncing back
Unique in the industry is the fact that if you do not like the exhaust note you can return it, within two weeks, for a full refund. Ever hear of that before?
The only caveat I would offer is that it does drone a bit around 2,000 rpm and I can deal with a little of that for an additional 18hp! It is not really a problem as I select another gear if I am in that rpm range for very long and 2,000 rpm is not usually an area I am in very long.
I will post pix tomorrow. Regards, Jim

Gears
Menehune, I will have a laptop along the next 6 weeks on the road and I plan to post some "over the road" thoughts here as I travel thru April and May. I especially want to get a long term evaluation of the Eibachs and also to see if the feathering issue rears its ugly head over the 6-7k miles on the road. With the new type air filter combined w/new exhaust system and tied together w/lower rearend gears, I am looking forward to some rolling testbed type of posts here on MY350Z.com over the next 6 weeks.
The ring and pinion (only) runs $483 from Courtesy. Install is another $500. I opted to get the whole differential swapped out for a total of $450 from a wrecked 6MT w/1,400 miles on it. Regards, Jim

Hey JimH, how much did the ring and pinion (or third member assembly) cost you? Let us know how it pull's after the install.

Can't wait to see some pics. Some sound clips.....even better. Hope I am not asking too much, but I bet most on the board are curious and excited. Thanks!

Also, please re-dyno after you return home from the road trip to see if your gains stay intact. I'll chip in if need be. My personal experience says not to trust instant mod gains, rather run dynos after several hundred miles.

Here is a little information for you that might help you out on that rear end swap........
The diff sizing is differnet between a manual trans mission and an autamatic transmission.
We have learned this from getting our spare parts form Nissan Motorsports and noticed we had two differnt sized diff's.....the stock one that came with the car and for some reason we received a spare stock diff.
I have the pictures back at work to show you but.....
The backspacing is differnt for the drive gear between the two. This would make the ring and pinion both differnet thicknesses.I can send you the pictures tomorrow......
and just trying to help.
The GHL exhaust looks like a great set up.
Cheers
BJ

Jim,
Which local dealer is selling this? (Pinnacle?)
I'm very interested in this exhaust, especially if it gives a slightly louder / lower tone. 18 hp is GREAT!
Thanks

GHL Dealer
I spoke to GHL today and they indicated that West Valley Nissan (downtown Glendale) is their only outlet. WV has two still in stock and they installed mine as soon as I asked after listening to one they had installed on one of their new cars on the lot. It took about an hour and fifteen minutes and I am pleased w/their work. Be sure and tell them this is via MY350Z.com for the lower price. Talk to Joe (parts mgr.). Yes, the power increase is noticable as are the decibels!
Interesting note, I installed the new (TrueFlow) air filter last Friday and did not detect any audible changes @ WOT. After the exhaust was installed today, I clearly hear the intake "pullin air"! Regards, Jim

TrueFlow filter
Droid, Try this: http://www.gcaindustries.com/
As I mentioned in another post, after installing the GHL exhaust today, I clearly hear the (stock) intake working thru the TrueFlow filter ($51) as never before. It really appears to have validated the "more air (combustion) out, more air in and vice versa!
I have a lot of respect for a man that makes his living mfg. and selling CAI gear telling me "we have tested and tried, but the oem intake is as close to right as you can get and in our opinion you will gain nothing by going to one of ours or other cai units for the 350Z " Regards, Jim
