Magna Flow Catback

anyone dyno before and after install, they are claiming a 10% increase in hp/torque but show no proof.

 

Hmm, if I had a dyno I might. I'm placing my order for one next week at a local shop.

They pretty much say that for every system they make as a blanket statement, and I don't think they actually quantify it. Do you have the page where they quote that at exactly?

10% gain on even 250HP would be 25HP, and there is no way in my mind that it could do that with just a cat-back system on a 3.5L V6. Maybe a couple, if that. I'm doing it mostly for the sound. I miss my dual in/out MF on my 5.7L Tundra. I know it won't be the same sound, but at least it's something.

On my Tundra though it made an already responsive throttle even more responsive. It got to the point where you could pretty much chirp the tires with a slight press off the line. It was really funny to watch other people drive it because it was so sensitive to begin with, and the exhaust didn't help with that, haha. They eventually fixed that in later models, but I know at least the '07-'09 was like that. I'm not expecting miracles on the '16 Taco though. It's just a muffler.

 

I agree 10% is a bit "optimistic" more like maybe 5% tops. As for more responsive throttle, the 3rd gens are drive by wire, so this may not be the case.
