I ran my truck again today at Island Dragway in NJ to see if my magnaflow exhaust did anything. Well it did. It was 58 deg and 70% humidity. My prior best was 15.77 @86.5 in late august with weather of ~85 deg and high humidity. Today I ran 15.164 @89.52. That's 0.6 seconds and 3 mph better. Everything else is bone stock, even has the factory paper airfilter.

Lets say I'm pretty impressed with the exhaust... and the better air also helped. I was just not expecting such a big increase of performance. It even felt like I could get another 0.05 -0.1 seconds out of her.

Well, it seems with a CIA I could break into the 14's on a good day. I might just have to try...hehe.

Beware of the 15838 fitment issues. Be prepared to weld and cut if you tackle it yourself.

I have the catback kit #15818, which uses the 5x8x18 single 3" in and out. It sounds great, no interior drone, and definitely helps the quarter mile times. Now, what cia should I get...

The hanger placement could have been better, but I got it on in an hour and the hfit is good without any heating and bending of the hangers.

without a doubt. Cooler air does add HP... Looking for 14's next year

I agree, most of that improvement was due to cooler temperature and less humidity.
