just got installed my borla exhaust and my volant cai with scoop.

Hi Guys I don't post that much here because i really didn't modify my taco that much.
But let me tell you what i did and my reviews.
I did put mobil 1 gear lube at the precise amount requires by toyota, and let me tell you i found the truck ran smoother than before. Also i noticed the fron differential was dirty (120K miles).
I replaced the oem spark plugs with the iridium, and I felt it was burning more gas.

2 years ago I put a flowmaster supper 44, it was an aggressive sound, but not that deep. So i decided to replace that.

I got the borla catback, and i gotta say it is quite, almost like stock, but more flow, but really i was looking for the sound more than performance.

the next day I installed the volant, which I gotta say, holes from the scoop didnt match. they send the union form the breather hose, but i think the union cut some flow, i think it is better to send a longer hose and done.
when the maf sensor rest, it is kind of cheap molded, i have seen it better. so really volant needs to improve in that. Also it helped with the sound but at 3000 rpm.

Anyway the truck is smoother, more responsive, and i might say it is saving me some gas, from my home to work and then home back is 40 miles round trip, so i will see how is that going.

I would say that is you want to go with a exhaust just for the sound DO NOT go borla.

Volant is good in the way of responsive throttle, but there ares some details to be fixed.
