In this episode of Rennthusiast Radio, I sit down with Darin Fister — the name behind one of the most well-known Porsche exhaust solutions in the enthusiast world.

We get into what actually matters when modifying your Porsche… and what doesn’t.

Darin shares his perspective on exhaust systems, backpressure, torque, and why many of the horsepower claims you hear don’t tell the full story. We also talk about how he built his business from the ground up — starting with DIY “Frankenstein” mufflers in his garage to building a global reputation after losing everything during the 2011 housing crash.

We also get into:

• Common misconceptions about Porsche mods
• What makes a Porsche sound “right”
• The difference between chasing performance and improving the driving experience
• His move from air-cooled cars into a GT3 RS — and why he ultimately sold it
• The “75 summers” mindset and how it’s shaped how he thinks about cars and life

If you’re thinking about modifying your Porsche — or just want a clearer understanding of what actually improves the ownership experience — this is a conversation worth listening to.

Rennthusiast Radio is all about real-world Porsche ownership — no hype, no borrowed cars, just honest perspective from people who actually live with these machines.

The internet says these engines are doomed. The data says otherwise.

In this episode of Rennthusiast Radio, I sit back down with Joe from Blackstone Laboratories to revisit one of the most debated Porsche topics out there: bore scoring. Our first conversation gave a lot of owners real relief, but it also sparked smart skepticism and great follow-up questions. So this time, we go deeper.

We talk about what oil analysis can actually detect, whether the bore scoring fear has been exaggerated, how much sampling bias matters, why oil change advice is often oversimplified, and what Porsche owners should really be watching if they want to avoid expensive mistakes.

If you drive a 996, 997, Cayman, or Boxster—or you are thinking about buying one—this is a conversation worth hearing all the way through.

Rennthusiast Radio exists to bring Porsche owners better information, better context, and better decisions.

If you own a Porsche, want to buy one, or have spent any time worrying about bore scoring, this Rennthusiast Radio episode will help you think more clearly about risk, maintenance, and smarter Porsche ownership.

Rennthusiast Radio is built for Porsche owners and buyers who want real ownership intelligence, not hype.

This episode of Rennthusiast Radio is a big one.

In this episode of Rennthusiast Radio, I explain why I made the decision to shut the podcast down at its peak—and why I ultimately decided to bring Rennthusiast Radio back.

After more than 80 episodes, the original run of Rennthusiast Radio had built real momentum. The conversations were strong, the audience was growing, and the feedback was overwhelmingly positive. But behind the scenes, things weren’t aligned in a way that supported where I wanted to take the podcast next.

Rather than force it, I pulled the plug.

What I didn’t expect was the response.

The number of messages, comments, and emails asking for Rennthusiast Radio to return made it clear that this podcast meant more to people than I realized.

...and that feedback forced me to step back and rethink what Rennthusiast Radio should be—and what it could become.

So this episode is the reset.

I walk through:

• How Rennthusiast Radio started
• What worked (and why it worked)
• Why I chose to shut it down
• What changed my mind
• And how Rennthusiast Radio is going to be different moving forward

The new direction is simple: fewer, more intentional episodes with higher-value conversations, amazing guests, and topics that actually matter to Porsche owners and enthusiasts.

If you care about real ownership experience, real data, and real decision-making—not fluff—this is what Rennthusiast Radio is going to deliver going forward.

And this is just the beginning.

In the next episode of Rennthusiast Radio, I sit down with Joe Adams from Blackstone Laboratories to break down one of the most talked-about (and misunderstood) topics in Porsche ownership: bore scoring.
