I posted the pictures and video link that he sent me, https://www.myg37.com/forums/media-share/181730-exhaust-depot-brand-new-catt-back-exhaust.html, but it seems that the pictures are mixed, What do you think?

 

again with this 8hp numbers. not sure where people are getting these numbers but that is not what it gained Peak power it gained 4.91hp. Throughout the power band the most power gained at one point was 13.4hp which is great. average power gained was 10hp across the board. But It dropped off up high down to around 3hp. But pure peak hp gained was 4.91. I am going to put the dyno sheet up now

 

I was just passing the info Hector told me by phone, that's all, you definitely know better than me, so your Dyno should show actual numbers. However, if I'm right, those numbers are still very good for your setup with just the Y-Pipe and the OEM exhaust...

 

That's even better IMHO. That means that it is gaining power under the curve which is where most of us like to see it. The G already does great at peak. But I know that you , UNV, coming from an S2K likes it better up top.

Also if 13.4 hp was in the mid range, that means that there was a significant increase in torque!

Also thanks for taking the time to do the dyno as well all the other research you've done for us.

 

no problem. I started a new thread in the exhaust section about the dyno
