This has been posted in many threads about drilling holes in the exaust. About whether it should be 1/2 inch holes or 5/8, 4 holes or 5 etc. But has any one who has done this experieced any problems? Lower gas milege, burning fuel to rich etc. ?

I'm just on the cusp of drilling some holes after realizing how quite the exhaust really is on the Stryker. As I posted in another thread, switch bikes with my Dad you see and hear my bike from another riders view and found out the exhaust is super quite when your not riding it (BMW quite). :'( And the exhaust I want is not available and may never be, so this might help me wait till I see something I like. Really nothing out there by Cobra or Vance and Hines I like.

I didnt notice any problems. Only better sound. I will warn you tho, i drilled the 4 holes in each pipe smaller than 1/2 in and i hated it. the next day I did the 1/2in and loved it.

Do the 1/2" holes. 4, 5 or 8. You'll probably be happy.
I removed the baffles completly. It's way loud. I wouldn't advise removal of the baffles unless you are looking for "harley" loud...lol

Only problem I've found is that the bike sounds so much better that I want to ride all the time and the new deck is not getting finished! Haha.

i first started with 3/8" then moved on to 1/2" holes. i couldn't be happier with the improvement, with about a thirty minute job.

i'm convinced i get a bit better mileage - nothing world changing but maybe 10-15 miles per tank after the drilling. i normally get the fuel indicator and f-trip way earlier than i did after drilling. i've gotten 155 miles off of one tank and i'd never have tried that before drilling. (and still had a bit in the tank). i want to continue to test to see how far i can get

Make sure you center punch where you are going to drill so you do not slip with the drill bit, you can also space them out more evenly. Just do not remove the baffles unless you want it to be real loud!!!

No problems other than my neighbors giving me the look for all the rumbling. Use a solid drill and good bits ( for metal) and your experience will be very positive with this. Touch it up after with some high heat paint (BBQ Stove stuff) and it will look professional. You will not regret this because the sound of the exhaust is way better. I have no plans to change the pipes now but will mod other items ofcourse!

I just installed my cobra swepts tonight, but drilling my pipes was definetely worth it, 100 times better sound than stock!

You tube has quite a few threads to listen too. Just got my stryker two months ago and the sounds needs to be louder. Cross between drilling or purchase...

Let me go ahead and tell you what your gonna do. You'll start out drilling two holes in each pipe, add two to each pipe, make them bigger, order aftermarket, never be happier.

This will happen in less than a 45 day period. Just skip all of the drilling and just order the exhaust you want and save yourself the time. You'll get the sound you want 30 days sooner. ;)
