As of now I have a corksport catback exhaust. Ive come to the point where I'd like to replace the rest of the stock components and I just had a couple questions.

Will this bolt right up to the cork sport?

Are there any other options? no custom work.


I have an S5 TII so I should be ok having the full exhaust safety wise ..correct? its more so the s4 owners who have to worry about porting the wastegate?

 

The link doesn't work. You may want to post another link. The way I understand, the s5 can aslo be subject to boost creep.

 

fixed the link. I was just reading around and I got the impression I would be fine with a full exhaust...

should i get an FCD, Fuel pump and port the wastegate too?

honestly the stock portion of my exhaust is leaking and i just want to fix that portion.

 

An FCD would probably be best. The fuel pump won't really help if the injectors aren't any bigger. Porting the wastegate would be good to to help with boost creep. Also, cold weather can cause boost creep a lot worse too for some reason. What was the piece on the link? It's just taking me to Racing Beats first page.

 

the link is supposed to go to the "cat replacement pipe with presilencer for 86 to 91 turbo"... now that i look more..the downpipe that comes with the rev TII exhaust system is 3inches..and the one i posted in the link is 2.5...

 

ok..so since my corksport catback works with the stock y-pipe..and the cat replacement and presilencer are made to hook to the stock catback..so i can assume they would work togethor lol.

now my question has changed to is it stupid to get this 2.5inch system to finish off my exhaust when i can get a 3inch? will the 2.5inch be safer boost creep wise?

 

It should work together. The 2.5 inch would probably be safer I would assume, because it should increase the back pressure somewhat, causing the exhaust not to flow as freely.
