I have seen a lot of these in the JC Whitney catalog. Does anyone have any experience with them? They claim HP gains but I am skeptical because of the amount versus the cost.

they are garbage.

use the search button, there is alot of info on here about using TBS.

i got mine from jc whitney and i believe it is a helix. to be honest it made a whistling sound, seemed to give a little better throttle response and maybe added 1-2hp. it sure wasnt worth 100 bucks

they dont really do **** but they do make a cool sound. i wasted 98 bucks on it but i knew it wasnt going to do anything except make my truck sound cool.

well not 100 bucks exactly, i just got a new catalog from them today and it is listed for my truck for $92.99 with 10% off. they usually do free shipping for anything over 75 bucks.

and yes they are online and i have used them several times with no issues.

They will only give you about 1-2 horsepower, nothing you will notice. Save the money for something else.

Not even.
