I think i did, i have the kn/aem hybrid filter as well. And i drive 75-80mph and i get 18-19mpg. So i say it did help me out.

 

Just wondering if anybody that has put the trd exhaust on their truck,and noticed any mpg improvements? Searched but didnt find anything!

Of the 20 months I've owned the truck, I've had my TRD exhaust on for 10 months.

My mileage has stayed exactly the same except in one area. I have the 6spd, so on interstate traveling 72-3 , the rpms are high at 2600. I used to get 17- 17.5 if I was lucky before the exhaust. Now she's pretty consistent at 19 mpg with the TRD. Must be helping at higher rpms only.

Best mpg speed of 55-60 remains at 21 mpg either exhaust. So basically your getting it for looks and sound rather than mpg.

 

It is hard to tell on mine ... 1 tank new truck without TRD ex. was 18.0mpg

2nd tank with TRD ex and 265/70X17 was 18.9mpg
3rd tank was 19.2mpg

06 extra cab V/6 Auto prerunner 3" lift

 

Ive had mine since Sept. 05. And I haven't really seen a difference. I see more of a difference on the highway by a few mpg's

 

anyone else have an opinion on this? i just put a TRD exhaust on mine over the weekend, and i'm very curious about how it will effect my MPG for better or worse...

Theres a good chance it will only effect your own MPG, so keep track of it. You already bought it so you cant go back now.
