MPG and Header?

Thinking about a header for my 08 Auto Access Cab with it's 4 banger and was wondering if it will improve gas mileage. Any info on this?

if you are going to invest in a header go all the way and put on a high flow muffler like a flowmaster 50 series or borla turbo to get the most MPG and performance. if you have a v6 consider increasing the exhaust tube.

Depends...want high end horsepower, or maintain low end torque?

I dunno about anyone else, but my truck spends a lot more time in the lower revs than the higher ones.

Flowmaster mufflers are not a "High Flow" muffler. They are a baffled muffler, and in most cases, actually cause a loss of hp.

+1

Flowchokers flow no better than stock. They are just good for making lots of noise.

Chris, what was that muffler setup that you tested that actually improved performance and fuel economy? (I have a fuzzy memory this morning)

I have just installed the DT header and have the stock piping with 44 series flowmaster also have the K&N Filter Charger 255/75/17 BFG M/T's and love the performance gains from this i training dogs for duck hunting Part time and tow a 6 hole stainless steel dog trailer around off road and also drive 200 + round trip to work and am pleased with the gas mpg of the 4 Cylinder beats a 6 all day long on MPG and the 4 wont be to far behind at the track on a head up race. This is my second 06 tacoma 2.7 4x4 picked my newest one up in Green Bay and drove it back to NC i got around 380 miles per tank running around 70 to 80 mph avg. I will be going to the local Dyno to check the gains and also will be checking the mpg and coming up with the totals. I love the truck and love the performance the past couple days that i have put the exhaust on it with the header i have had several compliments on the way it sounds. Just my two cents

I didn't think Tacoma people were actually worried about MPG. Im new to the tacomas that why I say that. I came from a 2004 Toyota Tundra Double Cab. If that thing got the kind of mpg even the v6 tacomas got I wouldn't have sold it.

Gibson, Borlar, are a couple that gave small gains. Best ghain was ith a Dynomax Super Turbo. Still, the gain was only around 5 hp.

Nice! I just ordered a Dynomax Super Turbo #17748. I called around Tucson, the cheapest place I found it was around $70 w/o install. Another shop was telling $105 and $145 for the install. I took the web and found it for $51.69 w/ free shipping! A local shop said they could install it for $30 bucks.

I read people on here saying its a good muffler. I came across these Tacoma videos that help me make my final choice.

Thanks for the link. I am going the same route. Should be a nice combo with the DTLTs!

Considering our displacement, 5 hp from just a muffler is pretty good.
