Kim1978 Posted June 10, 2008 Share Posted June 10, 2008 in addtion to the four item listed by homer, isn't a aftermarket BOV also necessary? I was told the stock one can only hold 1bar Quote Link to comment Share on other sites More sharing options...

I was told the stock one can only hold 1bar I've never heard that and still run my stock BOV with 1.2bar boost. Cheers, Brian. Quote Link to comment Share on other sites More sharing options...

hadyn Posted August 14, 2008 Share Posted August 14, 2008 Possibly a boost controller (electronic or manual) if your car wont boost upto 1.2bar without the cats in. Quote Link to comment Share on other sites More sharing options...
Thorin Posted August 14, 2008 Share Posted August 14, 2008 I was under the impression that this thread was to help do away with all the "what do I need to go BPU?" type posts. Looks like it failed. What it needs is a bit saying which parts are needed for BPU... oh wait, it has that. Quote Link to comment Share on other sites More sharing options...

Read the first thread very carefully. It's all in there. Otherwise, use the search button near the top of the page and search for decat or bpu or other key words and have a good read. Most of these questions have been asked before and answered numerous time so you'll save yourself a lot of time (and people won't be mean to you ) Quote Link to comment Share on other sites More sharing options...
Thorin Posted August 14, 2008 Share Posted August 14, 2008 To remove the cats, you need de-cat pipes. Quote Link to comment Share on other sites More sharing options...
MarkR Posted August 14, 2008 Share Posted August 14, 2008 what i was gettin at was will that exhaust system remove both cats? No. From the standard turbos, you get a small pipe with a cat, then another slightly longer pipe with another cat, and after that you get your cat-back exhaust system (clue is in the name). The Nur Spec will be from there back, and you'll still need to buy the 2 decat pipes. Here's a pic of the 2 decat pipes http://www.sonicsausage.com/Sections/Hobbies/TheCar/Images/CWDecatPipes.jpg Quote Link to comment Share on other sites More sharing options...

Guest jonte_j Posted October 17, 2008 Share Posted October 17, 2008 (edited) Where can i purchase this restrictor ring? Or do i have to make one myself? Where in the exhaust is it placed? I understand its in front section but is it before the 1st decat, between them or after?

I understand its in front section but is it before the 1st decat, between them or after? You can get them from some of the traders on the forum. Place a wanted ad, and I'm sure someone will respond. Mine is between the cat back exhaust and the last cat.. Not sure if that's the correct place but it seems to work. Quote Link to comment Share on other sites More sharing options...

I understand its in front section but is it before the 1st decat, between them or after? Further back the better mate I think...maybe between 2nd decat and exhaust? Anyone 2nd this?
