Yes, that is the one. Eric V did a great job as usual building up this one

 

Very nice! I thought long and hard on that one, was difficult to pass on.

 

Thanks!

I just hope that at least one member finds it helpful!

 

Can't thank you enough for the write up on this quick and simple mod. I did it over the lunch hour today. With your beautiful write up I was able to get it done in about 2-2.5 hours from start to full clean up. The bolts came off super easy. Only needed my 3/8 ratchet, 12mm socket, 13mm socket, and long extension(Passenger side) for all exhaust bolts. This is the quickest I have ever removed any car exhaust, thank you Porsche!

Volume increase is just as described. Not significant, but just a little more. This will hold me over till my #2020 delayed race pipe gets here.

Thank you again DC021!

 

I’m glad you gave it a go, and thank you for providing your feedback - Hopefully it’ll help other rennlisters decide if this quick project is from them!

🍻

 

Yeah, this is a cool mod! Nice work DC021! Interesting to hear that the drone is minimal with stock exhaust + valves open. That is encouraging.

Nice to see # of Minnesotans here. I'm in Minnetonka. We should have some group drives next season. Are you guys part of Nord Stern?

 

Will do. Just got the car today so is going to be a few weeks while I get use to the stock sound.

 

Nice work. It may have been me, I mentioned using rebar and a sledge hammer on cats.




Your solution is more elegant, I only use rebar because the cats I have done it to are much further away from the end of the pipe. I assume it’s like cats matrix and breaks up pretty easily.

I propose the “cheap bastard” GPF delete for a name.

 

I am not, I've been a member of the Northstar BMW club here for years, but not very active. I've just started looking into the local Porsche club website etc. I'd definitely be up for some group drives next year.

 

It the great tradition of shadetree mechanics this is a great mod, worthy of the coveted "Five Wrenches" medal, only reserved for "superior engineering without an Engineer's degree."

I will be tempted to perform this surgery on my CGTS once I get it in my garage.

I can't help thinking when I look at all the OAP options available, and the pricetags on them, that another shadetree job could be performed. Any competent muffler shop could manufacture the pipes for a lot less than those being offered. Likely they wouldn't look as pretty but they would perform the same function. Yes, mild steel would be cheap and rust out quickly, but aluminized steel and even better products are now available for a competent welder to use to fashion the required design. I'm not trying to take anybody's business away, but I just think Shorty or Fred or whomever down at the shop could build some that would work just fine.

 

Absolutely; let's do drives next season, with masks and social distancing, of course! :-) And, congratulations on your GTS. It's a keeper as the last NA of the platform since the next gen is gonna be electric!

 

This is a great mod DC021, there is nothing more elegant than simple genius.
I'm doing it, thanks.

 

👍🏼 Please do report back with your thoughts on sound output after!

 

you should have patented the idea and get royalties! There is a swarm of followers! Great job, congrats!

 

I'll be doing this very soon. Thank you for leading the way!
