Interest in Supersprint V1 & V2 headers

I noticed ECS removed alot of exhaust products.

I was fear mongering though I'm working through this.

This is moving - slowly - but it is moving.

Glad to hear its still moving!

The welds on mine (bought in 2018) are also kinda ass. The flanges were also a bit all over the place in alignment, didn't have a problem installing but they made contact with a heatshield (mine are installed in my M coupe). Heard a couple people's welds cracked eventually but hopefully I won't have this issue.

Given that SS is in Italy, I could see how they might have been off their A game in 2020.

Ss had some qc issues in 2020, they made a few posts on IG in regards to new equipment or something of the like they were now using to do things better.
People had flanges that were way off and welds that didn't look very good considering the cost of the product. I got mine in May of 2020 and only fitment issue was a few of the stud holes had to be reemed out a bit for the headers to slide on. I was using the extended etorx studs though and they made lining up even harder as you must start further out from head.

I think that bad run has come and gone and ECS took back what was bad.

I recently swapped from CPIs to SSv1s. The CPIs definitely had much better fitment compared to the SSv1s but my butt dyno does feel way more bottom and mid range with them.

Can someone confirm this? Is the quality concern bleed into poor performance?

I don't think it bleeds into performance. Me being the recipient of that header that my brother is talking about, I don't think should be drilling the correct hole for a EGT sensor for something that expensive. That shit was offset by a quarter inch.

I think quality applies more to fit and ease of lining things up while installing.

[pawa_k2001]

I don’t think performance is effected, I would/will still get a set but they used to be better.

Maybe interested but I am worried about quality. I used to have SS stepped headers in 2012, they were amazing. My brother bought a set in 2020, the quality was shit. First set was returned and he is still unhappy with second set.

I remember there was a thread on the old forum that said there were dyno graphs showing loss of torque in certain areas with the cpi single step that was alarming. I just sifted through pages on the z4m forum and it looks like that info was probably lost on m3forum.net.

Yeah— they make worse than stock power at low/mid range and unexceptional power on the top end. And made in China. But “stepped” is in the name, so somehow they get equated to supersprint.
