Toyota Tundra Forum

hey guys,
ive seen a lot of mixed reviews on all the different exhaust set ups! im looking to buy a dual rear(behind rear tires) exhaust set up for my 09 5.7 dbl cab tundra. i dont want anything over the top loud but i definitly like to hear the power.ive heard a lot of people only getting 1hp gain but ive heard as high as 14hp gain aprx. ive narrowed it down to magnaflow and flowmaster.any input from experience???

I doubt you will get a 14 hp gain. Go by user before and after dyno numbers, not manufacturer numbers.

Some people have complained about drone in the cabin from the Magnaflow. I have a Flowmaster 50 SUV on my truck. I like the sound, but I lost some mpg when I put it on.

I suggest you just go around and listen to them at the shops to see what you are going to get. I have a Banks exhaust wich I think is pretty quiet and a few people have told me its loud. I love my exhaust. No drone in my cabin.

thxs for the replys...has anyone heard which dual exhaust gives the most hp gain?

thxs toxarch. do u know the difference between the different set ups flowmaster offers? i'd really like to dual rear behind both back wheels...where does yours exit?

The difference is mostly sound. The higher the number, the quieter it is.

Mine are dumped in front of the rear axle. I don't care for exhaust tips much and prefer the hidden look.
