Ok, im getting ready to tackle the 4" exhaust myself, and have a few questions before i start.

It is sold with or without an adaptor. Do I have this right, that the adaptor would be 3" from my exhaust housing into the 4" for the downpipe?

I know he said its about a 3 hour job just for the downpipe, which will give me some great work this weekend. I also plan to get a new exhaust housing, either the 14 or 16cm non gated one.

Thanks

 

The dowpipes are sold with or without flange, you have the option. If you get it with the flange then you have the flange, adapter, and downpipe, which is all you need.

 

This is what he told me when I got mine from him, I still haven't installed it yet, the flange for the turbo you have to cut off of your old down pipe. The adaptor is from 3" to 4". I didn't get it from him since I already have one that goes from my stock down pipe to the rest of my 4" exhaust. I also got a band clamp from him then I found the same clamp at a local place for half the price.

 

Remember, a 14 CM housing is about 1 1/2" closer to the firewall than a 16 CM. Just food for thought. 14 CM will spool quicker than a 16 but will kill your top end power. I know from experience.
Good luck
