Ok, so I've decided to get some sort of devorced wastegate DP. I am definately getting a catless downpipe. (I already have a high flow cat on the way to replace the 2nd cat)
I am looking at the B&B DP: http://www.bbexhaust.com/car/wrx/images ... wnpipe.jpg
the Invidia V3 DP: http://www.optionimports.com/instdosuwr02.html
or the Perrin DP: http://www.vividracing.com/catalog/prod ... cts_id/145
If anyone has suggestions that would be some help. All the reviews I've seen for these are very good.
1st: The B&B DP looks good but I want to keep the O2 sensor in the stock location. Does it matter that it won't be reading the wastegate exhaust? It doesn't seem to me that it would but I wanted to make sure... 2nd: The Invidia has a cast bellmouth. Will it be difficult to weld an O2 bung into the cast metal? Cutting it would probably be a pain. And doesn't Stainless Steel and cast iron have a hard time staying together? 3rd: the Perrin looks like a good choice, but I like the longer wastegate tube of the B&B and the cheaper price.
Sorry for the long winded message. Any info would be much appreciated. Thanks All, Josh

The B&B isn't cast. It's Stainless Steel. The Invidia V3 is tho... I remember when I was learning welding them saying that it can crack easy or something when you weld to cast. I think because it's so hard, the weld doesn't get good penetration.206er wrote:cast bung? nahh.
is the b&b seriously cast? it would work with TIG but not too likely the exhaust shop can/will do that. maybe, you could always ask. a fab shop definitely would do it.
Yeah I'm interested.dwreck30 wrote:Off topic a little, but I have a barely used Invidia V3 if your interested.

No it's not. I don't think there is such a thing as casted Stainless Steel. The reason it doesn't rust (if I remember correctly) is because SS has little to no iron in it. And I think you need that iron in a casting... I'm pretty much just guessing tho...rallysam wrote:1st - Not reading wastegate exhaust shouldn't affect the reading

Well, I wasn't getting into the nitty gritty nor claiming to be an expert.
My point was this: I have a stainless TBE and my shop welded a bung in the stock location: no difficulty, no reliability issues

I know welding a bung to some stainless steel is no problem. I was wondering about the casted bellmouth DP like the Invidia V3. But I guess I pretty much answered my own question in my last post.
Now I just need to decide... Perrin or B&B...
