Are you backing your statements with fact?
It is a a stainless muffler as stated in my post. Thinhs do not have to be straight through to be maximum performance. Some scavenging and venturi effect can deffinatly help performance. It is also designed for a large v8 so a little 900 wont be a problem.
now im not a expert at all so i may be mistaken too. Just looking at input so thanks for the reply
Snrusnak clearly know little about performance........
yes a straight through or open header would give peak wide open horsepower if properly tuned but does not give drive abilty and torque would suffer.
You guys can claim I know little about performance, I clearly know a lot more than you realize. If you put that muffler on your bike you will be leaving power(and torque) on the table.
Straight through mufflers will outperform chambered mufflers every time, at every rpm, in both hp and torque.
Everyone thinks "you need some back pressure to help with low end torque". I don't know who started this rumor but it's complete BS. The reason many people experience a loss in low end torque with an exhaust modification is because they lose exhaust gas velocity. If you gut your muffler, the exhaust is not travelling through small 2" pipe anymore, it's travelling through a large say 6" pipe(not exactly a "pipe" but you get the point). The velocity of the gas slows dramatically at this point, which is why you lose scavenging and low end torque. Keep the pipe 2" the entire distance until exit, and you will not lose low end torque because the velocity of the gas stays high.
The smaller the pipe, the higher the velocity and lower the flow, the larger the pipe the lower the velocity and higher the flow. The best performing exhaust will be the one that is straight through and sized appropriately for both flow and velocity.
This stupid "backpressure" myth needs to stop spreading around the internet forums. I've been on forums for probably 5-10 years and have MAYBE come across 3 people that understand this concept. There's about a million people that don't.
I'm not telling you not to use flowmaster, I don't really care honestly, just was trying to help you out. Just letting you know they are not good for performance. It will only be slightly better than stock(and that's if it's sized appropriately, it could end up worse if you use a huge diameter muffler). If I overlooked the SS thing sorry, I just know that most of them are not SS. I know that ALL magnaflows are SS. It's just a better choice, or any other straight through muffler such as dynomax, etc.
So yes I have facts to back up what I'm saying. And I'm also not an "exhaust professional", but I know a lot about it and I know a lot about gas flow and scavenging.
I'm not getting mad at anyone, but it's really annoying when you try to help someone out, and give ACCURATE information, and someone else tells you that you have no idea what your talking about, when they are the one that doesn't understand it.
And I've seen several dyno's on cars and trucks that swap a flowmaster for a magnaflow and pick up hp(and yes torque at low rpm's also...).
