2 1/2" or 3"

had 3" on my small block..

used these mufflers...




this x-pipe from magnaflow




it fit fine. my springs were in stock location with a stock gas tank..





here is how it sounded. it isn't as loud as it sounds in the video and is quite a bit deeper sounding then in the video..

i now have 3" to the mufflers and 2 1/2" tail pipes because the 3" didn't fit with the triangulated 4 link.
