BXX Posted November 6, 2011 Report Share Posted November 6, 2011 Im going to start on my headers this week sometime. Got some bends and i've had the flange forming tool for a while so I can start putting that all to good use. Didn't know if anyone would be interested in headers for their car? Seeming nobody makes them, and even S&S is outta business and I don't recall if they made W-body headers. Quote Link to comment Share on other sites More sharing options...
jman093 Posted November 7, 2011 Report Share Posted November 7, 2011 I think maybe Ben at WOT-TECH is making them. Quote Link to comment Share on other sites More sharing options...

white4d96 Posted November 7, 2011 Report Share Posted November 7, 2011 (edited) Price dependent I may be interested in something. Would these be cat-friendly, or are you making longtubes with a cat delete? Also, I'm assuming a 3x00 is a 3x00 is a 3x00? As in, put them on my 3100 and a 3400 and if I decide to go 3500 top end, the flanges are the same?

GOT2B GM Posted November 7, 2011 Report Share Posted November 7, 2011 Make some 91-95 LQ1 headers Quote Link to comment Share on other sites More sharing options...

WrathOfSocrus Posted November 7, 2011 Report Share Posted November 7, 2011 I think maybe Ben at WOT-TECH is making them. They were pulled off the store because they are backed up on headers. The shop moved to Florida this spring right around the same time they got a load of orders. It will probably be a while before they get caught up and have them available again.

skitchin Posted November 7, 2011 Report Share Posted November 7, 2011 For me, it's all going to come down to price and modifications - not really interested in pounding in my firewall. I also have a feeling power and sound gains on a 3100 would be pretty minimal without a ported intake and high-flow cat. Quote Link to comment Share on other sites More sharing options...
white4d96 Posted November 7, 2011 Report Share Posted November 7, 2011 True. WHich may make it moot for me as I can't use a hi-flow. Quote Link to comment Share on other sites More sharing options...
Mater Posted November 7, 2011 Report Share Posted November 7, 2011 it would make a difference have you looked at the tiny log GM put on these cars lol. and you would need a cat converter any way because the stock DP will most likely not bolt up. and most modern cats flow pretty well they are not the old pellet style cats Quote Link to comment Share on other sites More sharing options...
white4d96 Posted November 7, 2011 Report Share Posted November 7, 2011 From what I've heard very few aftermarket cats work well enough to not trip a P0420. Quote Link to comment Share on other sites More sharing options...
GaPrix Posted November 8, 2011 Report Share Posted November 8, 2011 I'd be down, seeing the price and out come. Quote Link to comment Share on other sites More sharing options...
tornado_735 Posted November 8, 2011 Report Share Posted November 8, 2011 One would most definitely want to have a custom DP, or custom all the way back because (at least on the 3100s) there is a restriction right after the exhaust flange that closes down to about an inch and a half before opening back up. Not sure why it's there, but it most definitely has to choke these engines somewhat. Quote Link to comment Share on other sites More sharing options...
BXX Posted November 8, 2011 Author Report Share Posted November 8, 2011 They will work on all 3x00s and use 16ga 1.625" tubing. They will have a DP which will be cat friendly, i.e. you willl need to have a cat welded on, or I can do that for another $100 (Magnaflow Metallic Spun, shouldn't trigger a P0420 Cat Efficiency code) Price would be anywhere from $400-$800 depending on how much time I have in them, and how much I have in materials. My TGP will be used as mockup for them and the downpipe. So no pounding the damn firewall. However, installation of LX5 Intrigue fans may be needed (they are low profile) The passenger side dogbone mount will need a spot cut out though, not hard one bit. I suppose my best course of action is to use my 4T60e for mockup for clearance instead of the 284 as the auto takes up more room. If someone really wants LQ1 headers, bring me a complete LQ1 so I can do a mockup. I would discount $100 of a set, but the LQ1 will be mine:lol: Quote Link to comment Share on other sites More sharing options...

GtpKo Posted November 8, 2011 Report Share Posted November 8, 2011 FWIW, My 3" Magnaflow high-metal cat passed Ontario emissions with flying colors! You don't necessarily need hi-flow, just a bigger one will flow better. And one observation I've made after switching to headers on my 3800 is that you lose a little low-end torque, but get much much more high-end pull.

white4d96 Posted November 8, 2011 Report Share Posted November 8, 2011 I had heard bad things about Magnaflow cats before, particularly the high-flow varieties. I suppose if a code pops I could always pull the non-fouler trick, or use an emulator. All they do here is the plug-in test, no visual or sniffer tests...

skitchin Posted November 8, 2011 Report Share Posted November 8, 2011 I've heard from mechanics those emulators usually screw up a motor - causes it to lean out too much IIRC. Quote Link to comment Share on other sites More sharing options...
White93z34 Posted November 8, 2011 Report Share Posted November 8, 2011 the only thing a o2 simulator/emulator should be used for is a post cat o2. And then all it does is keep the SES lamp from turning on by giving the computer what its looking for data-wise. Never use one in place of the upstream o2.

xtremerevolution Posted November 8, 2011 Report Share Posted November 8, 2011 Bob, no more turbo? From what I've heard very few aftermarket cats work well enough to not trip a P0420. That's what HPTuners is for! Quote Link to comment Share on other sites More sharing options...
