seen several posts about many of you that have drilled several hole here. first, is it worth the effort if im not planning on new exhaust anytime soon and second, can someone post a picture of this?? not that i dont trust this suggestion, but i got burned by my friends on jeepforum once over a joke mod, www.kaleautomotive.com. thanks...

there are a few pics under the gallery. i dont have any pics but i have done it. i put 4 1/2 holes in each pipe. anything smaller will not sound good. it was kind of tingy but i LOVE the sound with the 1/2 holes.

well worth it. go on to youtube.com and do a search for stryker baffle. there is alot of videos of the before and after sound and how they drilled it.

 

[claytonandson]

did the drilling. drilled 4 1/2" holes @12,3,6 & 9 o'clock and then did 1/4" holes between each of those. could hardly believe my ears at the difference. soory, newbie excitement....

Did you try with just 4 1/2 " holes?
How big was the change with the smaller holes in between

 

[chris]

+1 I have my drill ready to drill some more holes 8)

 

[kcl-labrat]

post the pics if you do.

new guy here and just asking a stupide question... i know this has been discussed in mnay threads but is it really good for the engine to drill holes in the exhaust. i have to admit it sounds good on the youtube vids, but does the cat really hold all the backpressure to keep the engine from running too rich/lean? i kinda like the stock exhaust...well enough to wait for the right aftermarket.... but i would like a deeper sound

 

[kcl-labrat]

I've put on 2000 km since I've drilled mine out. No issues this far so I think its ok

aftermarket exhaust allows alot more air flow then drilling the holes no issues on mine and it seems to run alittle cooler the fan doesn't kick on as much. bike and atv manufactures set the air/fuel mixture alittle on the rich side stock so adding aftermarket exhaust you'll still be good drilling the holes your only letting out about half the airflow most aftermarket pipes do.

I started out with four 1/2" holes in each baffle and then ended up drilling 8 holes in each before I got my aftermarket pipes. Sounded much better than stock and ran great.

cobra sweeps?

 

[johnboy]

8 is great!

 

[kcl-labrat]

looks like a **** machine gun

 

[johnboy]

A Gatlin gun for sure Still cheaper then buying aftermarket pipes. Waiting for Cobra to come out with the black slip-on. supposed to be out end of this month I believe.

 

[kcl-labrat]

im waiting too but for blacked out V&H

 

[Stryker Lunatic]

I drilled mine yesterday too! 4 3/8" holes in each pipe, man what a difference. 3/8" is the biggest bit I have.
