Hey Kevin, I run rush racing slash down 3" slip on mufflers with no baffles on my '10 iron 883. The bike is currently undergoing a conversion to 1200ccs with 10:1 pistons and cams. Would these torque cones provide me with some back pressure without killing the volume on my pipes?

Also, Rush Racing offers torque cone's. Which set up would yield the best results? I'm thinking the rush cones might be an easier install, and I may not need to drill my pipes, but I'm not 100% on the installation process. Wanna make sure I'm not losing any bottom end due to my unrestricted pipe, but I would love to keep as much of the sound/volume as my unbaffled pipe gives me.

 

You will lose some bottom end with those pipes...regardless of if they have any baffles.

The Thunder Torque Inserts will give you a bump in the low and mid range, without taking anything off the top.

The volume will be very close the the same decibel-wise (within 1-3 decibels) but it will be a deeper tone.

This is accomplished by increasing the exhaust gas velocity/reducing engine pumping loss.

Torque Cones generally do little to nothing in terms of measurable performance improvement, and they are installed at the header, not the tail end of the exhaust.

I like Rush products, I am running a pair of Rush slip-ons on my 103, but cones...never seen any do any real good. Nice thing is they don't hurt anything either.

I think you're gonna like the bump you get out of your 1200 conversion!

 

Thanks Kevin! Which TTI's would you recommend?

 

W158's

 

Gonna place an order for the W158's today!
