    Replacing pre-cat and downpipe with custom piece

    Yes, it was something riddiculous like $400...but it was stainless steel and included a cat. However, I'd bet you could make something similar out of mild steel for about $200 or less (depending if you have a friend who can weld) without the cat.

    Headers?

    Hey, for those of you who have installed headers, what is the diameter of the pipe that connects to the secondary cat? Is it 2.0", 2.25", 2.5" or other?

    Here is the link to the original discussion on the downpipe...you have to read into a bit before they start discussing the Wagner pipe (you'll also have some fun reading the flaming between two members regarding illegable dyno charts - not to be missed!)...

    Replacing pre-cat and downpipe with custom piece

    Ok, I see what you mean. The gutting the cat part I took from another thread on here after doing a search for Traveler's posts. The problem I see with his system is the 2.5" custom cat-back exhaust he put on there. From what I have read on here (and elsewhere), that going above 2.25" with an n/a...

    Replacing pre-cat and downpipe with custom piece

    Thanks for the reply, Mike. I looked for Traveler (he dropped an "L" ;-) ), but most of his posts deal with a custom "shorty" header he designed. It seems to me he never replaced the stock pre-cat and downpipe. However, he did mention gutting the pre-cat but that still left him with the downpipe...

    Replacing pre-cat and downpipe with custom piece

    After many hours of reading on this forum, it seems to me that all can agree that the pre-cat and downpipe combination on the Protege is a serious exhaust bottleneck. While there has been much discussion about headers, I was wondering if anyone has just removed the pre-cat and downpipe and...

    Headers?

    Cork Sport (www.corksport.com) lists the AWR header at $572.00 USD. Has anyone else seen this listed somewhere else for cheaper?

    Headers?

    What about the HP Racing header? Details can be found here: http://www.nopionline.com/ (See attached picture). You have to look under Mazda > Protege > 2001. For some reason it only shows up under the 2001 model year. It's listed at only $240 USD and is ceramic coated. This header is mentioned...
