Motorcycle Mufflers.

[boygenius]

Hello. I have two stock motorcycle mufflers and was wondering if they would be too restrictive for a stock type 4 engine. They came off a 2004 yamaha R-6. The bikes engine is a 600 cc engine that makes 120 hp. Thats 200 hp per liter. would two of these mufflers breathe well enough for the engine. The reason I want them is because the only weigh 8 lbs each.:D Any help would be appreciated.....:D

They would probably work ok but 16 lb is a lot for a perfomance muffler, I know there are good mufflers out there that weigh less than that.

The're aluminium and stainless steel so they won't rust. I like them because they flow well and are still quite. Quite is a good thing when you like to speed...:hehehe:

Yeah it is... most of my tickets I got in my baja, I was running custom straight pipes:D It was loud even when it idled..... too bad you want the muffler to be quite, veilside sells a titanium teardrop style one, but it's dbs are around a 105...ouch!
