ok i have $450 i wanna buy a whole exhaust system but their way over $450. so i'm just gonna buy the 6port header which is $200. and the eccentric underdrive pulley $65 that leaves me with $185. is their anywhere that i can get a downpipe with the presilencer. or should i just get the dam thing straight piped. also where can i get some mufflers cheap? any good parts site for rx-7's other than mazdatrix,rx7.com, or rb.

 

You might be able to find some used parts in good condition on eBay

 

if you get a header and a straight pipe you won't be able to drive the car without ear plugs!

don't cheap out on a muffler, or it won't last long before it melts.

 

Get a header and a straight pipe going back to a dynomax ultraflow... its a little loud, but it sounds sweet, and it is very inexpensive.. I have a couple of friends who run a similar setup....
