A Tri­fecta of Per­for­mance Parts for a 5.7L Toy­ota

WHEN IT COMES to own­ing any kind of ve­hi­cle, hav­ing it per­form its best as ef­fi­ciently as pos­si­ble is im­por­tant. Mak­ing a ve­hi­cle breathe bet­ter is some­thing that you and a buddy can do in an af­ter­noon or a week­end day, even if you’re not par­tic­u­larly me­chan­i­cally in­clined. If you can turn some wrenches and screw­drivers, these parts can be in­stalled in your drive­way. Some things are best left to the pro­fes­sion­als, but any novice DIYER can in­stall the parts used in this ar­ti­cle.

We will show you some of the ba­sic steps to add a Gib­son cat-back ex­haust, AIRAID in­take and a Hyper­tech In­ter­cep­tor tuner. For our project truck, we went with a ’15 Toy­ota Tun­dra TRD Pro Crew­max. Our truck al­ready had a 7-inch lift kit and 37-inch-tall tires in­stalled (check out “Tall Or­der,” pg. 34, De­cem­ber 2016 to see how we in­stalled the lift), so we didn’t have to jack up the truck to get to the ex­haust. You might not have to ei­ther if you have a stock truck, but it could help when re­mov­ing the rear sec­tions.

Be­cause our project truck is a TRD Pro model, it came with a fac­tory TRD dual ex­haust, so we opted to re­place it with a bet­ter-flow­ing, stain­less dual ex­haust from Gib­son (P/N 67501, $812). To in­crease the air com­ing into the mo­tor, we re­placed the re­stric­tive stock air box with an AIRAID Per­for­mance in­take (P/N 510-213, $355), which came with a clean­able, oil-able fil­ter. To smooth out all of the gear shift points, which will in­crease your over­all mpg and re­cal­i­brate the fac­tory com­puter to per­form bet­ter, we in­stalled a Hyper­tech In­ter­cep­tor tuner (P/N 706001, $379). It’s a plug-and-play unit that re­quires zero fu­ture cal­i­bra­tion. All that we had to do was con­nect the tuner to our home com­puter and up­date it with the cor­rect map. For us that was the map for the AIRAID in­take, but the tuner pro­vides mul­ti­ple op­tions for a va­ri­ety of in­takes. If you in­stall the tuner with­out re­plac­ing the in­take, you don’t have to make any up­dates be­fore in­stal­la­tion. Hyper­tech also of­fers a spe­do­cor­rec­tor that will re­cal­i­brate the speedome­ter if you run larger-than-stock tires like our project truck. It’s also a plug-and-play up­grade.

Check out the next few pages to see how sim­ple it is to in­stall these parts to make your Tun­dra per­form a lit­tle bet­ter and sound a lot meaner.
