With the cone facing the end of the pipe, i have a deeper rumble and it is loud. Up here in northern wisconsin, deer are around every corner, so loud pipes really do save lives. If your on the fence about theses inserts, do it. D&K has a great product here.

Hey! Thanks for the awesome review!!! Those little things really are awesome. Its amazing to me how one little thing can drastically change the sound of the bike. Plus, the little extra umph doesn't hurt either....

Pardon my ignorance but wouldn't the OP need a free flowing a/c to feel the real improvement that the Thunder Torque inserts make? Seems like the factory lean condition should be addressed before feeling much of a torque improvement?

I wasnt able to get on the bike yet to see how much of a difference was made torque wise, but they improved sound and tune quite a bit which to me is worth the $30 alone.

You will feel an improvement in low and mid range torque with the TTI's in the exhaust, even with the stock air cleaner. This is because it increases the exhaust gas velocity.

With a HiFlow A/C, you will feel an even better improvement.
But the TTI's make the exhuast work more efficiently regardless of the A/C.

So, if you install them in the stock exhaust w/o baffles, then you will need to drill a hole in the slip-on? Will a standard drill get through the slip-on, or do you need something a little more powerful?

Yes, you will need to drill a hole for the TTI. A standard hand held drill has no problem drilling thru them.

Here's a video that may be helpful to you-

Thanks Kevin, I already watched the video, but it doesn't show any actual installation of the TTI's, hence the question. But if a basic cordless drill can get through, then I think I got it from there. Will be ordering some very soon.

I used a handheld drill to open up the hole on the slip on. Except a used a bevel bit which is a cone shaped bit. But you can use a 5/16 bit to open her up. It's only a hair off.

No prob. It's an easy install and you'll be happy with the results.
