Headers question

[ty056r]

I'm looking at a set of headers on E-Bay. The brand is "Sure win products". I'm assuming these are chinese. Does anyone out there have experience with these? I like the price, but I don't wanna end up with a piece of junk. I plan on installing the headers, relocating the O2 sensors and keeping the OEM secondary cats in place. What do you think?

I like a good deal as much as the next guy, but those headers on ebay make me nervous. Inexpensive and cheap aren't always synonyms.

I bought the surewinproducts headers on eBay a few weeks ago. I haven't installed them yet, but the quality looks pretty decent - quality welds and non-magnetic stainless tubes. For the price I felt it was a good gamble. I wonder if the high priced headers are really made any differently. I'll report back after the installation - I too have to re-locate the rear o2 sensors, keeping the secondary cats.

For what it's worth, I got Dansk headers with the O2 bung already installed (I believe that some of the ebay ones may have that too). My mechanic ran the second O2 sensors behind the secondary cats and everything has been fine. No CEL after about 1,500 miles so far - and I usually drive in a rather "spirited" manner.

I've seen the cheap headers on ebay as well. The price is tempting, and I also wonder if the Dansk, B&B, Turbowerx, etc headers are functionally any better. What worries me is cheap construction, and thus welds cracking, as well as poor sealing due to poor tolerances.

If anyone installs a set, let me know how it goes. You should be fine relocating the secondary O2s after the secondary cats.

I have many posts about headers, I have maxspeed motorsports headers with 2 o2 bungs per header which deleted first set of cats. Still no problems with CEL. I have had them on since last June.

For those of you who purchased the "surewinproducts" headers, please keep us all updated on your findings.

I have the Surewinproduct headers on my 99. They fit and sound great. I was a bit skeptical as well but figured for the price, it was worth a shot. I would be a guinea pig. Well I tried installing them myself and ended up snapping 3 header bolts off in the block so I stopped and sent the car in to Farnbacher Loles to have them installed. They ended up snapping 2 more bolts, but got the job done, I would suggest not trying the install yourself, broken header bolts Suck A__! I would not say I can detect any HP increase from the headers but it also does not feel like there was any loss either. I am not related to the ebay sellers in any way, just my short review. I saved the stockers so we shall see how well the welds and everything hold up.

I just recieved my eBay headers..and I have too say..they are of pretty good if not great quality. The welds are really nice and they are very solid. I plan on installing them shortly and will post my findings when completed. If I dont snap too many bolts and get wound up..I will try and document the full install for those who would be interested. Wish me luck.

Good luck on the header install.

thisi s the second thread I've read where someone bought the cheap chinese ebay headers, and after going through the hassle of breaking bolts, paying someone to professionally do it, and relocate O2 sensors - the end result was "I dont' think it's any faster".

sounds like big fat waste of $$ to me.

anyone here install cheap chinese headers and think the car was noticeably faster??

I tested these comparatively last week to the fabvspeed units as well as the NHP and stock arrangements.

When all the test work is done on the 2.5 power package I'll prepare some data.
