Straight pipe or Flowmaster? - Toyota Nation Forum : Toyota Car and Truck Forums

Should I get a straight pipe, or a Flowmaster 40 series muffler? Will either choice give me more horsepower and torgue, as well as MPG?

you would probably have a bad headache with a straight pipe...too loud. If you go too big on your exhaust, your 02 sensor won't get enough exhaust past it to read properly and your mileage will suck. I went with a stock audi quattro turbo muffler from a wrecked car. It's pretty loud. 2.5" in and out.

why dont u just straight pipe to a flowmaster? 2'' in 2' out or 2.25 both ways

i agree with rogerman. im gonna do 2in from a new cat, to the muffler, then nothing, or 2.5 to get it out the back. but go with the flowmaster. what size engine do you have, because you will also backfire alot with straight pipe, or a cherrybomb, with a 4banger

magnaflows are alrite straight thru desgin is good for 4cyls but i just doesnt make the sound a flow makes with a 4cly.

I have the 3.0L V-6. I have gone with Flowmaster on my past two vehicles, so I'm probably gonna stick with that.
