How many of you ground the head pipe welds?

Recommended Posts

If you did, and kept the stock muffler, did you notice a big difference or not?

I'm looking more for the guys that kept the stock muffler after grinding the head welds. I would like to grind the welds, but I am forced to keep the stock muffler for a while. If it's going to make a big difference, I'll proceed, if not and only makes a difference with an aftermarket system, I'll hold off. Besides, I'd rather go for the bigger tank, than a silencer

I've also read where people have removed part of the stock can, I don't want this thing to be loud, I have neighbors that I'm on good terms with, so far and don't want to change that.

Would an 03' need the welds ground?

I would think the Honda Engineers would have addressed that issue through the years and with new welding tech.

My '01 XRL had no blockage whatsoever.

Its a crapshoot as to whether there's any grinding to be done.

I'm planning on doing mine this weekend. I looked at them last night and I'd say the welds protrude almost 1/8" into the pipe.

I did mine, and I don't think it made any difference. Going with an aftermarket oversized header to see if that helps.

i doubt if there's much of a difference...that being said i ground my 01's they definately created a slight restriction in the exhaust path on my bike...hey Scott Summers did it :ride: ...or so it has been written.

it only costs u a little time...🙂 while they're off spend $5 on a can of black high temp paint and paint ur header just make sure to prep it very well and it'll hold up a long time...:D:worthy:

:banghead:

It doesn't NEED to be done. Take yours off and look at it. Honda isn't going to change a small detail like.

Take a couple pics, before and after so people can see maybe?🙂

I tend to side with you Mike. It's minimal at best. Even with a cam, etc...

The bigger headers will definitely help top end, but I think the stock ones are best for the low end torque.

Right, it's quick and easy to do. Plus it's fun doing these things.

I recommend black BBQ paint. I just did it to my XJ750 header. Prep it well and it is holding up great. 1200 degree protection. A little better than the 500 deg. engine paint.

Yes, it made a differance. No more off idle torque. I switched back to the stock pipe with the restictors. You know, it's not a welding flaw, they are there on purpose. If you open the other end of the pipe up a tiny bit, that works better.
