Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.
0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.
Suggestion
Your just replacing factory headers with aftermarket headers.
Leading evidence: 'Replace factory headers' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace factory headers' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Any of yall have any experience with Schnell Headers and can attest to any power gains, the quality, or any problems aka CEL? They seem like quite the bargain, especially when they are equal length headers. If yall aren't sure about what I'm referring to, here it is...

[QUOTE=sweet victory;12792590]**** quality
Appreciate the input, but was that good or bad quality?
Right and I hear of the muffler bypasses some times as well.
if youve ever put performance exhaust parts on your car, youll know they do make hp gains, unquestionably, but its better to put complete exhaust systems on , not just one part
Their product description states all welds are double welded. My photo shows that half of the collector has been fully welded. There appears to be a heat effected zone, but it is evident there's hardly any penetration. You can see a crack started at the joint and has propagated significantly.
It's hard to believe someone looked at this, and thought they did a good job and it's a joke these made it through QC. Wish I knew the name of the Indie that installed these because I would call them out on it too.
Reference for what a proper purge weld should look like if you're looking for quality. I used to work as a fabricator before I got my engineering degree. Feel free to ask any questions if there's anything you're still unsure about.
I had a set of Schnell headers on my 986 Boxster. They were loud and not especially well put together. Examples: the flange that mates to the exhaust ports on the engine block wasn't flat, and the 02 sensor bungs were full of sloppy welding.
The sound on the Boxster was terrible. I ran them for less than a day.
meh
It really depends and with our exhaust system, or any system really, it doesn't have to happen all at once.
I'll argue that the biggest bottleneck in our system is in the cats and then the muffler, and after that the design of the crossover. Plus, at 15 years old, removing the headers to put on something marginally better doesn't sound like a great idea, or, trying to extract snapped and seized bolts doesn't sound like a great idea.
This is a source reference. Confirm exact model applicability in the original material.
