downpipe and pre silencer
#1
after i pass smog, i wanna get rid of my cats (getting old and rusting out).....im not gonna pay $400 to change them knowing that a ticket would end cheaper...so i wanna go with a downpipe and a presilencer. i'm gonna keep my cat back for now, factory i believe, but will end up changing soon. i need a dp and ps that would bolt-on and isnt too expensive. what are my choices....i looked at RB, corksport and other stores and they all seem expensive....should i get a custom one? how easy is it to build one? i have all the necessery tools and welders and what not....what kinda metal should i use? 2", 2 1/2 or 3"? can i build a pre silencer too?

You can use a Borla XR-1 muffler as a presilencer. 2 1/2" is big enough. 3" will be too big, unless you have a bridgeport or something. You may want to go with a header instead of a downpipe.
ps i have a Rx7.com midpipe( w/ presilencer) for sale. PM me if u interested.

Just get some racing beat headers that collect to one and you can build a test pipe for the rest and/or use the xr-1 as a silencer after the headers like 13bace recommended.

Guaranteed to offend. Unmuffled NAs are so loud.

If you want to go deaf and hate other humans you could always run the header with just a pipe and a resonator...no mufflers.
