6 into 6 Exhaust

[NickChilds61304]

Guys, New to the forum, thanks for the add. I have a 99 Valkyrie with the OEM exhaust. I have been looking for a set of 6 into 6. This is my second bike from my GL1800 being my primary ride, and my Valkyrie being my pure fun ride. I found a set but they are pretty rough. The price is extremely cheap but I am curious if anyone has had any experience with something like this with removing the rust and possibly having the headers redipped? Or is it possible to just buy new headers and keep the pipes.

Having trouble adding photos, I can send over, needless to say they are rusty headers.

u will lose 10hp and mpg with them.

I had the 6 into 6 exhaust on my 2003 Valkyrie but changed them back to OEM pipes.  Mainly for noise but maybe better gas mileage.  I will see if I still have them.

Thanks, I would appreciate it.

That is misinformation and it should be stated that there are at least three different brands and types of six into six exhaust systems.

I presume the OP was talking about the Cobras, since they are the most common.  the two brothers and the other brand all lose HP, that is what straight pipes due lose HP.
It has been well documented by many legit dynos and even by FactoryPro.com on their dyno that the cobras lose 10hp from OEM pipes.

A friend of mine used to ride a 99 standard with Cobra exhaust with no change of jetting. My 99 standard is all stock and while riding one Saturday we inadvertently ran our bikes side by side on a four lane road. If there was a difference in horsepower between the two you couldn't tell it because it was like they were glued together. It did take my Tinnitus about a week to calm down from how loud his bike was. The inadvertently part was another friend that bashed Honda's all of the time was going to show me how much his real motorcycle a Harley Road King could outrun my bike and my friend on his Valkyrie just decided to join in. It ended up with the Harley way behind and the two Valkyrie's dead even. I prefer the stock exhaust over the Cobra exhaust but if someone likes the sound of the Cobra's I can't see the power difference if any would be that noticeable.

You didn't specify the Cobras, but even so it is BS based upon people who run a test with something to prove.  I have two Valks with Two Brothers', one with Cobras, and two with OEM exhausts.  I would be happy to run my bikes with straight pipes against anyone with stocks.  Oh, wait, I already have.

Do, by the way.  Not due.

Speaking of horsepower, you do know that gaining or losing seven pounds results in an increase or decrease of one horsepower at the road.

If one is worried about his horsepower there are larger factors than loud or whisper pipes to consider.

Incidentally, I've put two Interstates into the salvage yard.  Both were running whisper pipes.

What more I have to say is not allowed by the Rules.
