Completed the safety (needed rear pads) by changing rear pads and rotors. While it was up, got a brake flush. Brake fluid was definitely a bit dirty so a good decision.
I swapped the amp with another (found a spare amp, marked as 2007 in the trunk with a few other spare parts when I bought the car). The one in the car had a 2004 sticker. I did this because the one in the car would occasionally not power on. The one I swapped....first time around did not power on. This seems to be an ongoing thing so I think it's either a poor design that develops issues OR an occasional failure in communication between the head unit and amp. Amp then worked last evening and this morning. Fingers crossed.

Todd. is the car noticeably louder with the stock cats gutted? Did you make up a cone adapter or is there a part number and is this single or double cone? Thanks.
My exhaust is a bit louder, and definitely more snapping and menacing at high revs, low popping on downshifts. The X pipe made a bigger difference than the sport cats/gutting the primaries. Keeping the stock mufflers has prevented making enemies of my neighbors

For the cone filter, I used a K&N oil free filter ru-3105hbk

RU-3105HBK K&N Universal Clamp-On Air Filter>

Attach the filter using 3.5” diameter hose cut to about 10”, and a 3.5” steel joiner to attach the hose to the filter.

3.5" steel joiner: Turbo Piping

2’ of 3.5" silicone hose: Silicone Hose

Todd, thanks for posting your mods, and the results. Great job.
As for me, getting ready for her yearly service, Redline 10w60 oil ordered, new filter, I keep a stock of copper washers.
Last year was brake/clutch fluid flush, transaxle flush w/filter (Redline 75w90ns), along with oil change.
This year is serp. belt, front filters (going to try the BMC one), and coolant flush/refill. Just to kick off a good argument, I use Zerex G48 40% coolant 60% distilled water, and a bottle of Redline Water Wetter. Plus any items I may find.
Then its back to driving!

Stephen. What model year do you have and is there a reasonable aftermarket stereo for this (I have an 07 exec). I swapped amplifiers yet still get the occasional, unpredictable "no sound". And today, the cd changer stopped working and I get an error code.

Will have to look at non-functioning cruise. Won't ever use it but want everything to work properly. Will pick up a cheapie bluetooth unit to transmit the the mostly functioning radio (I don't want to contemplate changing the head unit due to the complexity). It would be easier if the occasional non-amplifying amplifier issue could be resolved but I think it is a common issue.

I picked up a Loudlink Bluetooth module, which plugs into the NIT in my Coupe. Works great… except of course for the sketchy amp

You made teh carbon fiber pieces or coated existing pieces with carbon fiber?
I skinned the oem peices in carbon fiber. To much work to make these from scratch. Not worth the time... But skinning for esthetics is quick and easy.

My cd changer crapped out so I did manage to find a used one that does work plus front and brake-grill parts for $100 cdn total! No argument there. Been driving as much as I can and also trying to fit in a plug change.
I was going to order a bluetooth unit but as the radio randomly refuses to work (amplifier anyways), figured that would be partially useless so will look for a stand-alone unit with its own speaker instead. Would like to either figure out this amp issue; seems like a common problem, or eventually replace the head unit. As for the amp, I think, as the sound never stops during use, just when starting up, that's it's either communication between the head and amp (as the head signals the amp to turn on) or possibly an overheating issue. the amp sometimes refuses to turn on when car has been sitting overnight so not sure of the latter possibility but something to explore; maybe an internal micro fuse. I have to amps and both have the same issue (as many forum participants report) with sporadic non-sound so this seems to be a design flaw.

Hunter alignment at Wheels In Motion specialists. Nearly 2 years since the last check and what a difference. These guys know their onions.

They do that. Had my GT done there.

Getting fed up with the franken-stereo in this car. Seems a common problem: no sound from the amp. As it is a common problem, I figure it is not an issue with my system but the system itself for the affected years. Mine is a 2007.
I found a used amp in the trunk from a 2007 and the one installed was a 2004 so the previous owner (or before him) had the same issue.
So, I figure this could be a signal issue or an overheating issue.
If a signal issue, as the head in these systems has to signal the amp to turn on, could be a design flaw that sometimes causes the head to fail to signal the amp OR a software issue that sometimes causes the head to not signal the amp.
I modified the amp housing to see if there may be an overheating issue but I will continue this in another stereo thread.
As for tomorrow, I am driving to Caliber motors in Woodbridge to have the undercarriage looked at. I may have a seep from the tranny housing and hopefully nothing else. Also a small exhaust leak if my hearing is accurate.

Swapped amp interiors into the modified (many holes drilled) housing to see if the problem is overheating.
Worked fine when started up this morning. Drove to the spray car wash, around 7 minutes away. bay was broken so started the car again...no sound. Entered the 2nd bay and shut car off. That bay was also broken but stereo worked.
Drove an hour to Caliber Motors in Woodbridge. Stereo worked fine. had car looked at, no issues underneath.
Started car and stereo worked. Went to Costco for an hour. Started car, no stereo. Drove home. All things point to a communication error rather than an amp issue so more testing the next time it stops working and I have time to look into it. This is making me nuts.
