i have seen a thread on here about drilling a hole on your non npp muffler for better sound. however, i wonder if there would be an easier way to go about it besides drilling a hole in the outer wall and then in the inner pipe. i had an idea as to change the angle of approach. So instead of me drilling a hole in the side wall and then the pipe, do you think it would be plausible to drill on in angle near the tailpipes into the pipe?
approch done on forum already vs my idea to that approach
If you want more sound while retaining the OEM mufflers without drilling through the outer muffler wall, there are still two choices. You could try the roto-router approach through the tips or the much simpler direct method of drilling the hole through the pipe prior to the muffler.
Of course, you could also record the sounds of other Vettes that have the dual-mode exhaust or an aftermarket system and play it back through the stereo on continuous loop. That way you could control the volume as desired.

That's a very good idea.
I did like the video of the muffler made into swiss cheese. That guy should become an inventor!
was a pretty big topic discussed on here and many people have done it instead of wasting 2k on mufflers. I would rather be made fun of for the idea of cutting and pasting my muffler then be the actual idiot who would waste 2g on something that garners no performance and no money in the bank. By the way, this is not a mustang forum, I asked an honest and adult question expecting an honest and adult answer back but I guess not. Also, I did it anyway and it only cost me 10$ for the right bit and materials and sounds better then my friends powerflo which he now is kicking himself in the *** for buying.
I would never have thought that it was a real thing to just drill a hole in your nice corvette mufflers to make it louder. I mean cutting them open, and replacing parts or removing parts sure. But not just drilling a hole. I guess you learn something new every day. In the past I only saw civic guys do stuff like this.

Actually, I couldn't believe you were serious.
So what size was that $10 drill bit? You need to post up pics and a sound clip so all the others can see what you did.
I recall that prior to NPP dual mode exhaust being available on coupe and convertible, many topics on the forum were discussing drilling holes into the stock mufflers to get better sound.
The thread that OP referenced was, apparently, one of the more successful attempts at this. Those old threads may not be familiar to most, and drilling holes does seem silly, but that was a popular modification discussed here. Now there are lot's of questions about putting the factory dual mode onto a car that didn't have it stock.
I suggest, OP, follow the directions in the post and let us know how it goes. Otherwise consider aftermarkets, or look to purchase a used set of NPP exhaust and just leave the butterflies open all the time, sounds great.

I have to agree with Tom.
Do you really want a Corvette that sounds like it has an exhaust leak because that is what you will get. The sounds that are produced by the various exhaust systems are designed to produce those sounds.
If anyone could just drill a hole in the muffler to get a great sounding exhaust no one would purchase aftermarket systems. If you just want loud you can just remove the guts of the muffler.
