Sounds great. Look forward to production. Great work!
Oh, are the connecting tubes stainless also?
Anyone wanna guess what this is?
Jason....email me as I need your phone number. I will be in Orlando June 11-14th with my parents and sister for an early fathers day weekend at Universal. We are staying at the HardRock inside Universal. I will not have much free time, but maybe we could meet up for about an hour early morning or late night. My car will be all complete with the following listed below.
HeadersExhaustJWT ECULevelTen TrannyEibach SpringsToicko Blues4.08 (gets installed on June 7th :-) ...finally)20mm rear sway barNew Wheels & Tires (maybe...TireRack ASA AR1's 18x9 rears were not coming in until mid June the last time I checked and yes the wheels are already ordered)
It would be great to meet up and terrorize some Orange Blossum Trial streets for an hour or so and get a good independent opion on my car as no ther Q owner has driven my car.

Brian, it's *uncanny* you would mention that because I noticed it but didn't realize it until you posted the question. My right leg & foot were obviously cooler after the trans/ps cooler install. I've only been in it a few days since getting it back on the road, I've been breaking in the new trans in the 3.5 TL-S, the one from Austin.
AZ, howinthehe11didyouknow about the babysitter? :boink I gotta get a pic of her with the schoolgirl outfit "on".
The "package" is taken care of.
Rob, I'm so impressed with your mods list. My cell is 407-421-9603. That'd be great to hook up with you when convenient, I'm in the booming metropolis of Apopka (NW quadrant of the city) you'll be in the SW, please don't judge my car too harshly, it qualifies as a work in progress.
Can't wait to see the headers & hear the exhaust. And the best part is, MAY WILL FINALLY BE OVER.
I'll be damned if every ticket I've ever received here or anywhere else in my whole life wasn't in May. Click it or Ticket, don'cha know.
But, as usual, I digress.

Perhaps you should post any pics you may have in the Member's ride section for all of us to enjoy :ylsuperHeavyDuty wrote:AZ, howinthehe11didyouknow about the babysitter? :boink I gotta get a pic of her with the schoolgirl outfit "on".

P.S. This exhaust deal looks pretty sweet... I've never dealt with exhaust or mods much. What is the reason for the x-pipe vs. keeping it dual all the way back?

Theoretically, when those two pipes crossover in the X, there's only one pulse from one bank or the other that alternate in the center section. The exhaust gas column or pulse is a high pressure area that leaves a resulting low pressure area behind it. That low pressure area serves to 'pull' or 'scavenge' the next pulse from the opposite bank.
I know the placement is critical, and yes, Greg could have gone with the older design H pipe instead, that would have resulted in a lower exhaust note, but the torque building nature of the X yields a WOT exhaust note that will strike fear in the hearts of all those around you, as well as a decline in MPG from your judicious use of the loud pedal.
You should be able to hear the pulses building in the X under your feet.

"dont want it to sound like stock"...........Stock doesn't soundSpecify the noise and frequency spectrum you want, including floor pan and seat vibration displacement levels desired in G/DB SPL terms. We have had lots of experience fixing loud.
For loud obnoxious worthless sound nothing beats the flowmaster.
Cheap loud exhaust is just, run 2 pipes from the existing premuffs. Your girl friend will fall in love with her seat......you'll never get her out of the running car.Not too riske I hope?

Wes wishes he had a girlfriend. Hopefully the NICO Mod shirt and the Q45 will help.... Maybe you could borrow one of your Dad's suits?
No, we will not offer different mufflers. We chose these because of their flow characteristics. I'm not putting the BRM name on ANYTHING that isn't functional (i.e. doesn't show positive results on the dyno).
If you want loud and rumbly, just go to a muffler shop and have them lop off the rear muffler and replace with straight 3" pipes for resonance.

The NICO shirt will cure ALL. I guess I want to hear what this sounds like.. I assume its gonna be nice over stock... I still have to play with the exhaust to figure out exactly what I want, and most likely it will end up being thie BRM exhaust, quiet for a luxury car but loud for the enthusiast!! 
BTW hitman, i got some pictures when i got a grey tux with hat! The ladies couldnt get enough of me, plus I looked like a mafia leader (the Q is at least a 4 body trunk, isnt it?)..
With the chrome piepans (and maybe some upcoming new rims) and new exhaust, i cant go wrong!! FORM A LINE LADIES, theres plenty of wes to go around!
Now back to reality!

You guys rock!
Great pics! Since I live only 2 hours from T3, and I will definitely do this mod, I can let Dennis run some tests on my car.
I am definitely on the list for this.
I wish I could affort the 4.08 rearend and a SC, but I can't put 1000 miles a week, on a car that gets 10 MPG.
IF I can find a new Q, for daily transportation, then I can justify these other mods.
I think a little more mods to the braking system are in the near future. I am reading everything I can, on the brake mods everyone else has had, and are doing.

I kinda agree with you. The 4.08 would allow the car to run in "D" a lot more, for around town driving, but I think, at a steady 72 MPH, the 4.08 would net a lower MPG, than the stock rear gears. Since I spend 2 hours a day at this speed, I would see a lower fuel economy.
If I drove a lot of miles, at 45 or 55 MPH, then the difference would be negligable.
I still want to wait, until I get the second Q, before I do this kind of modification.
I may be getting my wife a new G35, then I can drive the !30t to work, and get 28 to 30 MPG! Then the Q will be free for lots of mods.

Im just saying, heres the deal. The 4.083 rearend only changes the gear ratio by 15%, so AT MAX youre looking at a 15% decrease in MPG. So instead of getting 22.5 mpg, youll get 22.4 mpg... VERY insignificant to me!!!!!
Id do the mod, but I dont have the money, and IMHO id rather put in a 90-93 transmission

It effects it 15.4%, imposible to be otherwise at the exact same speed..........unless some how some magic [beyond the laws of physics] makes the engine more efficient at a slightly higher rpm.
If the engineers had found that magic rpm where things get miraculously better they would have chosen a different diff gear and taken advantage of it.
Now the 3.694 [the 97-01 gearing] [+4.4%] might be more transparent regarding mpg.
We do quite a few diff swaps in SC400/LS400 [use the gear set/diff] from SC300 manual trannies...........roughly the same %.
As the 90-97 LS/SC V8 had the same more economical ratio and owners wanted to get a little faster acceleration.
We had 2 pay us to return it to stock [luckily we kept their old diffs].
I'm trying to not be negative [just neutral] on the swap as it does help zero to 70 mph acceleration. Once you've done ecu and exhausts there really isn't much inexpensive gains besides it.

Everything Dennis is saying is correct, and has been observed by me (10 tanks of gas thus far with the 4.08).
Wes, Fred wishes he was seeing 23mpg. Ain't happening.
There is, however, a caveat in all this: You can't just ASSUME a 15% decrease in fuel economy based on the 15% reduction in final drive ratio. Keep in mind that the 15% additional torque will, at times, leave the driver free to use LESS than WOT, thus reducing fuel consumption and mitigating (to a certain extent) the negative effect of the lower ratio. I am personally seeing less than 10% decrease in fuel economy, 1-2 mpg over the past 10 tanks.
