A fresh set of slash cut single wall tips finish off this Valved Exhaust install nicely.

 

Here's our customer autocrossing his 981 Cayman S with our Competition Headers and factory PSE

 

Here are some pictures the man, the myth, the legend John Gaydos at our dealer, AutoQuest Motorsport, sent of our 981 Long Tube Street Headers post installation on his customers car!

 

I appreciate the kind words! Install was a breeze, product looks to be great quality, and the customer loves the sound and the extra "pep" to say the least.

 

 

Welcome to Rennlist! Most of the gains will result from changing out the restrictive factory catalytic converters. You can expect around 10 whp and 15 whp in max gains from our Sport Headers. We're using large HJS HD 200 cell catalytic converters which make a noticeable difference. Adding the rear exhaust to the equation would net around 5 whp and 5 ft-lbs of torque. The main benefit of the rear exhaust is being able to have a vivid, full flat six sound without any drone - it's focus is more on sound quality. Here's a relevant blog post.

If anyone would like to do before and after dyno runs at an accredited location with our 981 products we'll pay for third party dyno runs to get real, repeatable results.

 

 

 

SOUL Long Tube Street Headers paired with an Akra rear exhaust during a “Touristenfahrten” public driving session on the Nürburgring in a 981 GTS!

 

How's it sound for those of us who can't spring for the Akra cat back at $7,000.00?

 

While it's not a GTS, here is a 981 Cayman with the same headers and our valved exhaust - and you can get both for well under $7,000!

Are there any discounts for your headers or just the cat back systems? I have PSE and just want the headers for the track. Also, I would be interested in dyno testing before and after on my 981 GTS (stock... for now) as I have access to a local mustang dyno.
