If my XS order takes a whole lot longer because of them being on backorder, I may pull the trigger on these. I googled them and read reviews and did not find a SINGLE bad review. (even on the BMW forums)

MSRP is $379, but erzperformance.com has them for $189.

i vote you to be test car.

 

i wouldnt do it. That extra flex pipe may mean they havent fitment issues, but you can be the test dummy. You may have stumbled onto somthing

 

Yea, I just don't like the extra flex....but no biggie. I'll just chop it and reweld it.

 

+1

 

I got back-ordered from ssautochrome also. I ended up getting something similar to the one you pictured from a brand called top speed for $110 shipped. I used new acura manifold gaskets instead of the ones they supplied and heat wrap the flex points. So far after a couple of days no issues.

 

I wonder if that extra flex pipe would cause any interuption in air for a hp loss.

The thing that got me, was on the BMW forums they go over quite well. Those guys are more picky than we are! lol

 

Just keep in mind that you will have to install it first, then splice in the section of pipe if you expect it to fit. If you are going that far, you should heat cycle the headers a few times to let them settle into shape. As long as you're doing that you might as well wait and see if they even make noise. I've had to weld in flex sections to eliminate noise, but typically it's done with headers because it's cheaper than holding tolerances that would allow them to fit properly.

 

if bmw owners like them then screw it im look at them too

 

Let me know how this goes.. maybe we can get a bunch of people in on a group buy?

 

perhaps. I'll probably end up making my own soon.

 

I just can't get rid of the resonance from the XS headers. I put in a new flex pipe and it's still there. I think I'm just going to give these a shot and see how it goes.

 

^ give me your old one then.

 

They buzz at 2600-3000 RPMs

 

Keep it updated brah!

 

Did anyone end up getting these?

 

wheres your DCs?

 

holy revival but yea did anyone

 

Don't buy this shit. Is the same thing of megan racing and all other shit. The flange that bolt on the head doesnt match exhaust port just check in the pic... seriously dont buy this!

 

Still not in stock...they say they'll be in by May but we'll see

 

Agree. I wouldnt buy this, especially because of the 2 flex pipes.

 

Fuck it, I'm buying Comptechs

 

^ baller.... buy me one to.. kthxbye.. lol

 

I have these headers and they don't fit right. I'm just waiting till I can find something else to replace them. I had a post on them about a month ago. I figured out what was making the noise I have. The flange on the front side don't seal right and the gaskets keep blowing out.

They never did fit right though. I had to pull them hard with all the other bolts loose when I was trying to get the flange on the cat bolts. The pipe needed another good inch at least.

 

You won't be dissapointed. I've had mine for almost 8 years and not one single problem.

 

Thanks for the info, sorry it didn't work out for you.

 

sigh.... comptechs it is...

i can believe im gonna spend 1k on something that probably cost 50 bucks to make

 

I know it's hit or miss, but I have XSPs and believe fsttyms1 does as well. Mine have been on 2yrs without any problems. If you go the cheap route, I suggest you have them ceramic coated (Jet Hot or similar) It'll help a little more with the performance, but it will also help with the integrity a bit as well.

Oh, and buy slightly longer bolts (stainless steel while you're at it) for the header to pipe and such. It'll make it easier to bolt up.

normally i would go the cheaper route... because bad reviews arent in high numbers.. however.. it seems about 50/50 with XS's

im not one to go through the trouble of returning items and such.. i want to know what im buying wil work with no hassle..

in this case its a 700 dollar difference so i might look more into the XS's for money's sake..

on a second note.. the ceramic ones in my experience have had didnt hold up and flaked off and rusted over time... i think i may finally go with stainless steel and wrap them..

 

Yea ive had xs for over 2 years. the welds on the flanges started to leak but I rewelded em and they are holding up real good.

 

I hear you on the $$. That's why I went with XSP. I also just got the SS headers and sent them off to a pro shop for the ceramic coating.

Here's who I used.

Besides Jet Hot, there are many local specialty shops, you just have to search in your area for one. Here's another expample.
