Yes, we sell the O2 Extensions as an option to purchase. The TSP True Dual exhaust should work just fine.

Thanks

Ok. Will I NEED the o2 extensions?

I can always add o2 bungs on the inside of the collectors too. That's not an issue for me.

Has there been any other clearance issues besides the aforementioned k-member tab?

And, just out of curiosity, what is the easiest way to get these headers on: from the too, bottom, do I need a lift or can I do it at home?

u guys should offer an option to weld up the emission bungs for like 30-40 bucks more. Would be good for people who cant get to someone to weld them up . Unless its not worth the hassle for you guys .

When do you all plan on fixing the o2 location? I'm really tempted to order a set early this summer.

I'll be in for a set as soon as you release the "race" ready ones and fix the o2 location. I just picked up an 02 WS6 and need to get rid of the stock exhaust ASAP!

The fitting location works just fine. Its just easier to route the wires on the other side of the tube. We probably wont have a race version until the end of the year unfortunately.

Thanks

Would you like to be added to my list of "safe" eBay headers?

https://ls1tech.com/forums/generatio...primaries.html

If you can confirm that your primaries are 1-3/4" throughout, then you'll have a customer for your longtubes and y-pipe

I dont understand why a race version won't be available on the next batch. I mean they are actually doing extra labor to add the emission fittings to the header. Just stop doing it.

The new header design we sent off a week or so ago is a race version with 1 3/4" primaries.

The current ones it looks like are the same dia. as other Ebay headers. We never measured them previously. They are however they are a thin wall tube. Which will bring the inner diameter closer to a 1 3/4" tube with a thick wall. Probably why performance gains are close to say Pacesetters etc.

Thanks
