New here, and I am really enjoying my Star Stryker.

The stock pipes are cool looking to me, and sound pretty good, but I decided to drill the end of them to see how they would sound. I worked up to 1/2 " hole from smaller size, and I staggered the pattern 2-4-8-10, kind of like a dice #5, including the center hole. I like this better than 12-6-3-9.

Anyway, it sounds great. Not tin sounding or choppy. Very low, louder rumble, but not too loud. Also get more of the cool real motorcycle idle sound with our single crank pin engine.

Apparently the O2 sensor and Cat are farther up the pipe so we can drill the muffler or cut it off and use slip ons without affecting the engine.

Ride On.

This mod was the first mod i did to my bike, after owning it for 2 days! ;D

I also used Barbeque Grill heat resistant paint to keep holes from looking drilled.
I don't see any need to drill the center plug, it sounds great with these 4 1/2" holes.

That is cool! I was thinking about do that to mine. So, do you have to remove anything to drill them or do you do just drill it on the bike? I've never done this mod. Thanks!

Can be done on side stand.
Put the bike in gear so it won't roll forward as you push with the drill.
I used a marker to make symetrical distance marks of where I wanted the holes.
Put something on floor to catch the sharp shavings left behind.
Use a small drill bit to make pilot holes, don't push too hard, the fast speed of drill will do it, then switch to the 1/2" bit.
Keep the drill speed up and hold firmly so you don't bind and catch when it breaks through. If it does catch, just back it out and try again.
Once done, I used masking tape to cover the tail pipe chrome edges and newspaper to cover rear end parts, then spray painted holes and inner tail pipe. I used BarBQ spray paint because it's heat resistant to 1200 degress.
Good luck.

Thanks for the info Bill! I may give it a try next weekend. I'll let you know how it goes.

Nice write up Bill! Very well explained. A good rule of thumb is, the harder the material, the slower the drill speed.

I was wondering if anyone had done this yet. I'm hoping to talk Desiree into letting me mess with her exhaust and make it a bit beefier sounded.

I did this same mod to my Raider. I started with four 1/2" holes per pipe. Then went to 1" holes. Then went to eight holes: four 1/2" and four 1". Then I dremmeled out the entire backside of the exhaust. Then I pulled the baffles.

Each time it just sounded better and better and better.

I now have Cobra Swepts due to an accident I was in. The insurance company covered the cost and the Raider factory exhaust runs about $3000, where the Swepts with commander was less than $1000 and I love the look of the Swepts. I was able to use the rest of the money on other mods to the bike.

I'm guessing the Stryker exhaust costs about the same.

Has anyone removed the baffles yet? If so, what do you think and how does it sound?

 

[backinblack]

I want to get the black swept cobras for mine, but they dont have the Power Commander 5 ready for the Stryker yet. So I guess I'll try drilling them out. Does this affect your FI any?

You can get aftermarket pipes without a processor......its just
when you start fooling with air you need it.

I know, but I've done that before and I had more popping and didnt get all the performance out of it till I had a PC put in.

 

[dejablu110]

good thing you didnt go with a raider then.....they pop!

 

[ares x]

I like the popping.

I was going through a tunnel on the freeway last night on my Raider and purposely ran the RPMs high and then let go of the accelerator just to hear the loud cracks in the tunnel and let everyone know I was there.

 

[dejablu110]

heh heh........ye-eeeeeeeah!!! Thats what Im talkin about!!

oops sorry, lost it a moment.......Im curious about the Stryker,
will it pop?! Or not??!!

 

[RedStar Raider]

X, i dig the decel pops myself!

Does anyone know if this voids the warranty to drill the pipes?

 

[dejablu110]

You can put custom and aftermarket parts on and it doesn't
affect the warranty.

I agree 100% as this was discussed at length in the Raider forums I been involved with.

I didnt have any problem with warranty work.....depends on
the dealer you go to also.
