Hi guys so i did a bunch of reading and searching on here and thought i would just ask my question and get the proper answer...
Ok so i have a 2001 blazer 2dr and i had the stock muffler removed and a FM40 installed now am i able to remove the factory custom bent pipe and install a straight pipe from my new muffler out the back?
i was thinking of even putting a Y pipe after the muffler then running pipe to the back will that be fine and i wont lose no power because that custom bent pipe will bot be there no more?
I dont under stand the whole back pressure thing..
Everything is stock from the engine to the muffler..
please help and thanks

 

You can do what you like at the back. You won't loose anything back there.

 

Thanks for the fast reply..
I forgot to mention theres the FM40 muffler it has a 3inch out with 3 inch pipe that was custom bent to match the factory bent pipe..
When i got the muffler they told me i had to get the pipe from the muffler back all custom bent to match the factory bends lol...

 

Well that was BS. And 3"... WOW. Way larger than necessary.

 

Yea going to a different shop for this stuff to be done lol...
factory pipe is 2 1/4 correct?
So would 2 1/2 be a good size with the y pipe and just stick with the 3inch outlet muffler
