where can u see the one chambers? do u have a website where u can read up on them or hear a sound clip???? if so please share...

 

I'm currently planning on ditching my Original 40 series for straight pipes.... And if the 10 Series is screamin kick azz bitchin at the devil, I'm guessing that straight pipes would be equal to kicking the devil in the nuts?

 

Actually the IMCO is way louder and deeper than the FM40. I changed my FM40 to a SI/DO IMCO and I still smile everytime I floor my truck. It sounds so badass. I know for a fact it sounds way louder than my old FM40. I have a 5.4 and people tell me its loud *** hell. I know you wont regret it. If anyone thinks their FM isnt loud enough, they should try this on. Yall wont be dissapointed.

 

Get the IMCO. Its way louder and deeper than the FM40. If yall want louder yall wont regret it. I sure didnt

 

LMAO

now that makes 2 all time great quotes

 

The one chamber Flowmaster mufflers are under the Racing section not the Muffler section on the Flowmaster home page. I'm pretty sure the have a sound clip for it too.
