Can't comment on these yet as far as
power gains go since it's snowy out. Factory Pro claims 1-2 hp gains
to the wheel, but we'll see. I'd imagine I'll see alittle more
throttle response also. I may have to swap the stock stacks back in
sometime so I can get a side by side comparison ride. Pretty easy to install, no harder than changing an air filter. Fit and finish is ok, not as good as the stock items of course. Did have to sand the lower edges of the stacks alittle due to some flash catching on the throttle body and making it difficult to seat the stacks correctly. |
