Feature:
Upgrade the L5P to achieve higher-flow by bolting on PPE OEM-Length Replacement High-Flow Up-Pipes.
These direct replacements have a 46% larger flow area over stock, which results in a deeper-breathing power-plant, while maintaining the mandated Federal emissions standards of stock.
The Length Up-Pipes are manufactured from stainless steel. These new Up-Pipes include the superior internally-sleeved bellows, also manufactured from stainless steel.
This system is engineered to take the abuse of high temperatures and high pressures, while promoting increased exhaust flow and lower EGTs.
Customer Reviews
Great fit
Test pipes solid but doesn’t line up 100%, need to do some modification on it.
Great quality for the money. Welds are great and packaging was great. Shipping caused the outer box to be quite damaged but the product was perfect. I would order again in a heartbeat! No brainer!!
Looks nice, decent quality, and easy install
This replace the original piece and was made even better.
Let customers speak for us
Good running carburetor. This carburetor runs very well, I just adjusted the choke each morning for a few days to get the cold start choke setting where I wanted it then adjusted the air fuel screws and it starts and runs really well i'm impressed for the price.
Easy install and fit perfectly. Good pressure for the washer fluid.
Great Service, really realiable.
Yes, will install it tomorrow
Just good
no more problem with the engine light thank you so much
The original one is hard to find, this one is a decent replacement.
This is exactly what I was looking for. I got some drag bars and I needed to raise it up one inch to clear the top of the front forks.
These work perfect, no issues and they look good in black.
Sure enough perfect match went rite in place of the old one. Put the bike back together and soon as it got fuel she fired up. First time in 8 years. Having an issue with getting rpm out of it without stalling but I will mess with it.
Clutch on bike is seized up so I can’t ride to test out but it so far has done what I want and that’s running bike to work with. Can’t fully blame the carb due to other un known issues with old bike but time will tell. So far I’m thrilled this carb got the bike running rite out of the box
Fix my error code problem
Got my carb, 2 days later them I expect but it looks great
Looks good
Got it in 4 days.
I ordered these GE water filters and am extremely happy with my purchase. They are GE brand and the cost was much lower than my local supplier. Shipping was free and they arrived well packed and quickly. I was so happy with the purchase that I recommended it to several friends who also purchased them. I will definitely order again when needed.
Definitely recommend if you have a the code and need it gone for inspection. I run a repair shop, and this is my second time buying here. Really impressed! Planning to order more next time—hope you can give me a good discount.
