yes chibi you are right. i have been doing more reading on the SLP site and others looking for more technical data and they are all saying that its 304, not 409 like i thought i'd seen. i realize that the muffs, res and tips would all be 304 but the pipes are like you said usually 409 like i thought as well. they do that because 409 is easier to weld and its less costly. but serves the same purpose minus the shiny looks. but cannot find anywhere stating 409 now and i know i'd seen it somewhere. oh well it'll still sound and look great cannot wait to get it.

 

please post a sound clip of the slp cat back thx

 

Here it is with my latest set up as seen in my sig: (it was windy out that day so the sound didn't turn out too well - it sounds much better in person).

 

i can hear it but yeah the wind f*#ks it up

 

I will try and use my good camera and get another clip up on a not so windy day.

 

thanks
