Hi guys, first post on 986, I have been following this thread with an open mind and decided to go ahead after all the good reviews. Went & bought a 14mm by 250mm all purpose drill bit as my oval pipe is spot welded on. Pushed the drill bit as far back as it would go and let rip. When I shine a light down the pipe you can see the hole at the back but you can also see more metal directly behind the hole, it's even scored by the drill bit & I'm sure I would of gone through this if I'd carried on pushing. Does anyone know what this will be and should I drill through this as well? The sound is better and I'll be taking it out later to test drive. Cheers
