You will notice a little gain with the WR-SR especially when you start hitting 3,500 R’s… I do notice a difference over stock. Has a great sound with stock exhaust but if you upgrade your exhaust, you will no longer here the SRI. You will hear it in the exhaust tho, as the engine breathes better and the exhaust will get a bit more aggressive sounding at these ranges, so the SRI will affect the exhaust tone a wee bit.
Use the stock clamp when you attach to the throttle body, it works much better and is easier to put on than the standard type clamps that come with the unit. That’s the hardest part of the job, is getting it on the throttle body and getting that damn clamp on right, once you got that, the rest is a piece of cake.
I don’t use the cold air, in fender tubing… I left the stock tubing in, which sets next to the filter, you can see my review and pictures installed here http://clubsciontc.com/fo...cret-weapon-owners-27312/
As I stated in my review, I don’t like the standard clamps as they need to be torqued down periodically. T-clamps should remedy that issue but haven’t replaced mine yet.
Remember, use the stock clamp to attach the SRI to the TB, you’ll be better off and it’s easier to get on and doesn’t need to be retightened like the other clamps. Us a pair of vise grips to hold open the clamp until you get it into place and than remove the grips. It’s a little tough but once you get through this step, the rest is straight forward… After that enjoy your new sound modulation...
