Banging like crazy? What do you mean? Are you referring to the EcuTek 2-step launch control?

 

LOL. It seems I am. My bad, didn't realize that's what was going on. Good thing you didn't launch the car into the wall. That would have been a heck of a thing.

What's it sound like when it's not going whacka whacka whacka? I bet if you cruised around that garage in second gear while a buddy filmed, it would sound awesome.

 

Here are some more pics of the rest of the exhaust....showing the resonator, extension, cuts and welds.

 

Have to say, for a shop modification that looks really clean. I've seen shops butcher the living Hell out of a job like that. Did they do all the welds as well or did it come pre-assembled and they just hung it for you and just applied the extension?

 

Here's a cold start video of the car outside. There's a leak where the mufflers meet with the midpipe so I have to apply some RTV sealant next time I'm under the car.

 

Nice. Those little pops and burps make for a very aggressive sound, far more exotic that you would expect from a car like this. My exhaust doesn't share that characteristic. It's note is equally deep, but consistent. Seems your choices in cats and cans has created something unique.

Never understood the value of "cold start" videos, but once it tamped down to normal idle, it sounded fantastic, Z.

 

Thabks! I'm glad you like it. I kind of took a gamble with the AAM HFC, not many people are running them. They're a 200cel count, and surprisingly didn't throw a CEL. I may take up your idea on getting a custom bracket welded up because I'm not very comfortable with them just hanging like that along with my $1500 exhaust.

 

That random pop in the exhaust is what the Jag is known for. Same for the Mustang GT350. Looking forward to hearing it in person come August. It would be very cool if someone did a video montage of different exhausts at the meet-up.

200 cell count is low, like the original Berks, IIRC. Good luck with the CEL. I bet you're right on the edge.

No brackets on the AAM, huh? If you do pay someone to custom weld something, there goes your cost savings. Here:

The CEL won't be an issue because I have ECUTEK.

 

Really? Dammit, Z. That's twice in two days you shut me down. I need to stop commenting.

 

Hahaha, I actually look forward to our conversations on here! I'm always learning something.

 

They had to cut on either side of the resonator section, re-position, and re-weld. Also, new hangers had to be welded on. However, due to the exhaust originally being for a 370z it was close to begin with so it did not require much modification. The extension is a single 12-inch long pipe from topspeed.

Shop did a good job overall, but I was also standing right there watching and commenting (in a nice way, making friends with the guy). I feel that made a huge difference in the quality of work.

 

Wow, that's some fat a$$ piping! I'd be dragging that exhaust all over the place. LOL

 

So does the ECUTEK disable the sensor? I have seen issues with that in the past with OBDII emissions. The car will throw a "not ready" and you won't pass. (Not a CEL)

 

ECUTEK can disable the code, so it can still pass emissions. It won't show up as "not ready". These HFC didn't throw a code anyways, so I'm not too worried.
