Here's a vid of cold start. No revs. My neighbors will hate me enough already. It settles into a nice tone after about a minute

They replace the secondary cats which makes it louder, you can see how they rate the sound levels here:

I just installed the axel back dual single tip touring edition on my SS yesterday and love it! Definitely loud on cold start up but it settles down after it warms up. Plus in I few weeks it will be broke in and quiet down just a tad more. DynoSteve at the RDP store took care of me. Great exhaust system for the price!

What makes you think it's going to quiet down after break in?

Actually, exhaust is quietest brand new and will get louder over time.

Ah I see. I assumed the secondary cat deletes were standard.

I’m curious as to how the axleback track exhaust is louder than both resonated/non resonated catbacks, anybody have any ideas? Looking to go loud and axleback is much cheaper comparatively.

A LOT louder than I was expecting. I'm so glad I didn't get the track setup. I wouldn't call the system drone free. It's not bad though. If you lug it in top gear you will get some cabin resonance. There's some coming up through the gears at part throttle as well. It's about as much as i would put up with. Any louder and I'd have to ad the resonators and/ or secondary cats back in. It sounds absolutely BRUTAL when you roll into it or floor it. I had them poke the tips out a bit to see how I liked the look. I don't know if I will keep it like that or not. Easy to change.
I was curious what my AFR was with my current mods so I had them do a couple dyno runs while I was there.
Only mods - Rotofab dry Cai, Tony Mamo ported throttle body, and awe touring catback with no resonators and performance link pipes.

Found something strange during the dyno pulls. You can see a dip in the graph around 4000 rpm. It's showing the throttle closing a good amount. Blake said he was staying in it the whole time. Did it on all three pulls. No clue what's going on there. First pull was 605 rwhp. Next was 602 rwhp, 571rwtq. AFR hung around 12.5 which I was happy with. Very perplexed by the throttle issue though.

Again I want to thank weapon x. I will definitely be doing some more mods through them come spring.
Glad to hear you're happy man! Sorry I missed ya yesterday.

I'll see if I can get the log to see what's going on, but Blake is obv well versed, so if he said the throttle is closing, he knows what he's looking at. The system deletes your secondary cats, so unless you've deleted the primaries previously and turned the CELs off, it will still have the cats and COT is a setting as well that would need turned off. On my ZR1, it kicks in and takes the fuel from 12.5 to 11.5 AFR. So, seeing your AFR flat line all the way across, it certainly looks like the COT is off to me. Has the car been tuned as such?

COT will show up as a little dip, but the AFR reflects the added fuel almost immediately, especially on our Mustang dyno since the pulls are lonnnnng. I think a 7th gear pull on the A10 is about 15 seconds if I recall, vs. about half of that in 6th; however, 7th is 1:1 for accurate readings.

I would tend to agree with the above statement though, if the car is closing the throttle at a certain RPM, I doubt it's the intake either, it's most likely a flaw with the TB. Regardless, I'll take a look and see if I can help offer some insight.

I didn’t notice the AFR in the posted graph.....and it is strange that it isn’t obvious that it richens up with the power dip.

That being said, my mustang load dyno graph both stock, and with 2nd cat delete catback has the identical dip, in the identical spot, and correlates exactly with the data for COT turning on. A tuner I know said every ZL1 he’s had on the dyno goes into COT on the stock file (but that tuner is kinda iffy). But my car certainly goes in COT no matter what on the dyno,...nothing to do with weather or heat soak either.
