I was recently at the harley dealer getting my bike retuned again and the service tech told me right off the bat that i was loosing 10-15 horsepower/torgue because the samson pipes i had on my bike is restricting the air flow.He said their was a weld inside the muffler that made the air flow split causing restriction.I was wondering from you guys is this true about pipes causing you to loose horesepower? My pick up off the start is great.[1st] gear 0-25mph, [2nd]gear 30-35,[3rd]gear40-50mph,[4th]gear 55-60mph,[5th]gear 60-70mph,[6th] over-75mph.

 

If the pick up is great and your happy with it, who cares?

I'm no expert but I have read a ton about this on here. He may be right, but he's talking about peak numbers. That weld inside is giving it better low end torque which is why your bike takes off so well. The torque comes on early. I have Rinehart true duals. I have good torque numbers but they are high end. I'd give up a few numbers to have the torque come in a little quicker. Had I read all the information here on this forum first, I would have bout a 2 into 1 but I am too cheap to go and buy another set of pipes and I love the sound I have.

Don't chase numbers. Unless your racing and have a ton of money. You'll need it if you are chasing numbers. Peak numbers mean nothing if they come in at an RPM your bike never sees with your riding style. It sounds like you are happy with the performance you have so enjoy it.

Use the search function and you can read here non stop about pipes and performance.

 

Thanks and you are right.I am happy with my pipes that i have,but it just amazes me that you can leave 10-15 horsepower and torque on the table just by the pipes alone.

 

10-15 HP loss. Sounds a little exaggerated to me. What did he recommend as a replacement?

 

I'm thinking sales pitch in the works. 15 is not realistic.

He didn't recommend anything untl i asked him about it.He said any good pipe that didn't have the restricted airflow in it. He said no to rineharts,no to pythons,no to vane/hines,he said yes to hookers and the new pipes harley has called power something or another i can't remeber the name in the book he showed me.

 

I am not a fan of chasing numbers either, unless you are planning on carrying a copy of the dyno sheet around with you, seat of the pants feel is more important than a graph. If you like the sound, throttle response, etc, its not broken, don't try to fix it. Unless you've got a pile of money you want to part with, chasing the numbers is useless IMO.

 

+1 with hdrider, it will never end unless you have the unlimited wallet.

 

Hey Mark, what are the wheels on your bike? They look really good in the picture.

 

Get what sounds good unless you think for some reason you absolutely need more power (i.e. you live in the hills).
