i found one @ http://www.fastscions.com/descendant...2-20-2004.aspx curious as to what gains this would put out and if anyone on here is running one i dont remember seeing a thread so link me if im wrong lol

 

its only a s-pipe.....alot of people use theses to complete there exhaust....its not a test pipe

 

Thanks, my friend has a 350z and called it a test pipe wasn't sure what options we had available

 

yea usually,test pipes elminates the secondary cat on the midpipe,for some cars,but in our case,since our cat is welded,we just have the s-pipe,or turbo vehicles are downpipes...but i actually have the invidia s-pipe on my 1st gen scion,didnt do much difference but make the exhaust a little deeper

 

Oh gotcha ill wait till I'm running turbo no point buying s pipe and header just gonna wait thanks again

 

Wait, sorry I'm really confused. My understanding of a complete exhaust system includes: headers, downpipe, and catback exhaust. Am I missing something? What is the difference between a s-pipe and a down pipe?
