Failed exhaust mod!

[jmerch44]

so I attempted to drill a hole in my exhaust as done by other members on this forum, it sucks. but the problem isn't with bad sound, the problem is that there was no change at all. I went out and spent $13 on a 12 inch drill bit and drilled two holes down in each can. I used a 3/8 drill bit. I have a 2007 fz6 and i just want louder exhaust to hold me over until I can afford new slip-ons. I know it wouldn't sound good, but its certainly better than the non-existant sound you get stock. does anyone know if I just screwed up or is there something different about the 07's.

May I suggest a LARGER drill bit??? 3/8th isn't much of a hole.

should still make some sort of a difference though. no difference at all?

Well if you know for sure that you'll be getting slip-ons,then drill a few holes in the pipe before the muffler,it worked for me till I built my own exhaust kit.

I read somewhere in here that it has to be about a 7/8" hole.

 

[jmerch44]

I'm gonna try drilling a few more holes tomorrow. hopefully that makes the difference.

ive done 4 3/8 holes in each pipe and i noticed a change with every hole, but there again mine is a 04, take a picture and show us.

Well, you drilled it once, so what do you have to lose? Drill it, GRUMPY

 

[jmerch44]

so I drilled some more holes in the can bringing me to 3, 3/8 holes in each can. I finally noticed a difference, but very disappointing. I know that it is a cheap mod but I expected it to be a little louder. I am glad that it doesn't sound really bad though, guess I gotta take what I can get. thanks for all the advise. does anyone know of any cheap slip-ons that sound ok?

I have an 07 and I made mine look like swiss cheese I put so many holes in it, I also cleared out the cat and, I kid you not, it sounds exactly like it did the day I drove it off the lot. I think the mufflers are designed differently on the 07 than, say, the 04-06's.

 

[jmerch44]

I wish someone would.have warned me about the 07's earlier. If I would have known I would have saved myself the trouble. I'll just have to save up for an aftermarket slip-on. at least nothing got worse.

 

[aussiejules]

I dont get what the difference would be, unless they are packed and the early not. When you drilled threw did anything else come out of the drilled hole.

To notice any kind of difference you must enlarge the bit size i hogged mine out with a 7/8" bit and it definatly changed the tone of the bike, just enough to hold me over till i got my Scorpions.

I can't believe that anyone would purposefully make their exhaust blow. I'm gobsmacked.
