I have searched for 4 days and have found not found anything. I have a 23 vanguard on a gdlt im wanting to gut the factory muffler but wondering about it running lean afterward. I don't want a loud muffler im just wanting to do it for less possibilities of something falling down in the motor. Any info on the possible lean condition would help. I know when most do exhaust they change carbs. But im not looking for power just more safety..

Leave the jets alone.

You'll be fine.

Ok thanks. I didn't figure it would change the flow that much but wasn't sure. When you search on here no one ever says if they had to do any carb work when adding exhaust. I just figured it may run to lean with a little extra exhaust flow. But thanks for the quick reply.

It wont hurt anything to take all baffles out and leave just the exit pipe in tact will it?

It will be louder.

But just slightly louder, at idle can't tell much difference at all

I don't mind slightly louder. Just don't want super loud. Does anyone know if you have to cut both ends off on the 23 like people was doing on the pro drives?

I cut it open with a cutting wheel, removed the inner pipe/baffle then had my muffler shop weld it back. Charged me $60.

Baffle was very restrictive. It's louder but gained lots of power. I cut it in 1/2 from the center up.

Good luck !

I only cut one end off of mine and it was rusted enuf for the baffle on the other end to come out without cutting both sides.

Mine hasn't rusted much yet im doing this before it does.. ill cut both ends off if need be but I don't want to cut in the middle.. thanks for the input tho

Mines gutted and I'm running a stock carb. Runs great most of the time!

Sounds and performs great. I left about 2” of pipe inside both ends. Just removed the baffles. Also milled the carb and modified the air box and inlet. I think in total I got an extra 4 hp from a cheapo home fix. Woke up the 23 VG. Big time.

This thread is worthless without
pics....?:?



It's not slow....its big...and you just see it for a long time.

When I tear into mine ill take pics and post up..

Well I got it gutted haven't welded it back up.. took pics and tried to upload but it wouldn't for some reason.. the baffles was absolutely terrible to get out..

That oughta do it....

If it don't I don't much think the baffles will go back in lol

This one sounds pretty good, and didn't fool with carb jetting. Just a lot louder.

Rudy what did you mill on carb and also how did you modify air box and inlet? Im sure others will find this useful to. Thanks
