"Finally! Something to give power down stream of the turbo..."
For some, this has been a long waited post...
I picked up 42DD's 3" turbo-back exhaust with a GLI-style 4" single tip from 045GLI (thanks!) back in early January.
And with the cruddy weather Colorado recieved for 3 straight months was horrible, so I couldn't get the sucker on.
That's up until just over the weekend.
Evan@42DD [2kjettaguy] packaged and shipped it with 75% hardware (which we agreed on) and with new gaskets.
* downpipe w/ flex pipe (with EGT bong, and two O2 sensor bungs)
* straight center pipe with catalyst & resonator (with center wing hanger & post-cat O2 sensor)
* over-axle pipe (with hanger)
* Magnaflow muffler + 4" high polished exhaust tip (with hanger)
I picked up nine 3/8"-11NC x 1.5" bolts for the bolting the adjustable system together.
Removal of the original exhaust on my vehicle (with 41K miles) was too difficult, but more time consuming since I only tilted the driver side of the car.
But getting in the new one... wow! A breeze!
With the individual parts, it was a cake walk to bolt up the downpipe and snug that down (with a new gasket, I purchased) right away.
Then transfer the center wing hanger from the existing OEM unit to their system...
And then getting that up and in; bolted down to the floorpan and loosely connected to the DP for adjustment.
Then installing the over-axle pipe; Evan instructed me that he accidentally placed the hanger extension in the "backwards" position...
No problem, you can easily rotate the hanger frame 180deg around, no problems.
And then get the muffler on (with GLI lip I've had sitting around since October!) and get that 'close' to final position.
Snug up all the bolts starting from the DP and working your way to the muffler...
And wha-la! Turboback installed!
So, just how good is in terms of built quality?
42DD did their homework and got it right the first time!
There is a great clearance on the DP, and the entire system all the way back to the muffler tip.
I didn't have to rebend, retweak, cut, modify, bust, remove, or destroy anything on the car or on the system to get it on correctly.
And there's not a single rattle or clank when I drive the car.
Evan, I just have only a slight suggestions + comments (if you produce a full line-up):
* could you add another 1/16" or 3/32" to the radius where the adjustable slots are for bolt up? It's extremely tight to get a socket on and not lodged on.
* maybe supply a turbo-to-DP gasket as apart of the system (if you produce a full-line)
* great O2 sensor placements; no problems for install + clearance
* good placement of the adjustable slots; everything was reachable.
* downpipe bolt-up was awesome; didn't have an issue feeding the DP through the firewall + heatsheild.
So how the sound?
I'm sorry, but I DO NOT have any sound clips or videos to show.
However, I'll be descriptive as possible.
Upon first start-up, the idle out of the rear indicates you've got something install.
At low revs and soft take-offs inside the cabin, there's not much to hear that you have a different exhaust.
But, the moment you give 50% - 100% throttle, it's quite clear you've increased size and sound output.
The tone is really refined and does not give any raspy or turbine whirl out of the tailpipe.
At cruising speeds, you can't hear it over the wind with open windows...
Expect when you're on the throttle, trying to pass someone on the highway or local business section of town.
Cabin noise is extremely minimal and medium radio volume (from OEM Monsoon unit) drowns out most of the exhaust noise...
There is a slight, but healthy buzz when the car is on the gas, but that's probably caused with the engine mounts I have installed.
Hey, I've been 16 before; and I don't need a loud exhaust anymore..
This system fits my wants almost 100%!
Installation Time: 8 (1 = alot / 10 = alittle)
* great matching of individual componets; some of the bolt=up locations are "tight" to get a tool in
Learning Experience: 7 (1 = already knew / 10 = read-up and learned new things)
* the removal of the old exhaust was more difficult since I wasn't on a rack; but learned that this install wasn't difficult at all
Performance: 7 (1 = nada / 10 = tons)
* once on, the car does quicken in reaching redline; but no dyno infomation at this time
* if produced as a full-line up, it'll be one of the most cost-effective and easily adjustable turbobacks I've ever dealt with
Overall Rating: 9
* extremely good craftsmanship, good construction, good R&D, great customer service and communication, etc, etc
No, I don't have pictures of the install; was too dirty and nasty to bring out the camera and take step-by-step photos
However, I will have finished photos in 24 hours of this post.
