I have had a set of Roadhouse slip-ons ordered since 5/26.......backordered. I got impatient and decided to try and gut out my stockers. I am really glad I did and MIGHT even cancel my slip-on order!

I used a 3inch hole saw to remove the endcap/back plate and then used a long screw driver and hammer to chisel the mounting points inside the pipe.....there are three in both the top and bottom pipes. After that I used an extension and a uni-bit (tapers up to 1/2 inch) and drilled 4 holes in the plate of the next baffle. I left the baffle in to keep some backpressure (SET and CAT are still there, too.)

The result is BAD TO THE BONE! Much louder and a very deep tone! I have a PC III and it actually feels like the bike is a bit MORE responsive :dontknow:.

Thanks to Rockfordrider for words of encouragement/help. :bigthumbsup:

This is what it looked like after the 3 inch hole saw:


This is what it looks like after breaking the metal mounts inside the pipe:


This is what came out of the pipe:


Here is a video of what it sounds like after drilling the extra holes in the next baffle wall. On my computer speakers, it sounds pretty close to "in person":

That's almost what the Bigshots sound like.:doorag:

It's the CAT that I have a problem with....not on a motorcycle for me. Seems like I also heard a little SET valve squeal....;):D:bigthumbsup:

What did you use as a guide to keep the 3" hole saw centered to cut? The top end cap is angled so please do tell. I drilled my baffles over the weekend but would like more sound.

Do you need a tuner for this.

I didn't use anything as a guide; just good ole' muscle power!

I have a Power Commander on my bike as I have aftermarket air intakes too. If you only do the pipe mod, you are probably OK. Your bike will let you know; if it starts bogging/hesitating, then you need more fuel.

Well this past weekend, my 9 mainly feasted on sport bikes. I guess I got to let her eat something with a little more weight to it like HD baggers LOL. I am running a Metz 260.

sweet! love the sound Bobby! :bigthumbsup: Now just gotta cut them down shorter... ;) Get busy bro! :D
Thanks, bro. :doorag:

Sounds good exactly what i did to mine except I got rid of the cat and left the set. Sounds like a vtwin sportbike around 3500-4000 rpm I love it no need for aftermarket pipes. Plus Im like you i like the look of the stock pipes .

I agree! I was surprised to hear that the Bigshots sound the same as stock but much louder, deeper and growlier (if thats a word) Not tinny sounding at all :bigthumbsup:

Sounds good Bob. Looking forward to hearing them in person soon. If I like it I may have to do the same thing on mine. I was wondering if it would be possible to tach weld black wire mesh (like on the Ducks Covers) to the end of the pipes so it covers up the gutted/jagged metal in there :dontknow:

use a de-burring tool to grind to the ID of the pipe so it is a clean shot all the way in.

Thanks for the compliment and you have a very good eye. Yes, that is my GSXR 600.....man, you guys don't miss anything!! :eek:

thought you would have already done that by now
I really wasn't hating the sound of the stockers but I ordered those slip-ons over 2 months ago and by gosh, I was going to get some more sound one way or the other! :doorag:

I may get the Roadhouse anyway just to shave some weight off from the heavy stockers.

Yup...that will be my next step. :bigthumbsup:

Sounds great Bobby! If it weren't for the extra weight I would have kept mine like that. :bigthumbsup::bigthumbsup:

Big-B, you can use two hole saws to keep it centered. Put a 1 1/4" hole saw on along with the 3". The 1 1/4" goes inside the center pipe to keep the 3" hole saw centered.
