I ordered a set of street headers from Jamie back in November but didn't get to install them until today. Install took about 5 hours, including removal of bumper, heat shields and rear wheels. I'm using the Dundon headers with an Akrapovic non-race slip on muffler with carbon tips. No hitches with the install and everything aligned perfectly. The only thing I did that was not in the instructions was tucked away and zip tied the 02 sensor cables as they were too close to the pipes.

In terms of performance and sound -- I haven't driven the car in a while but can definitely feel a slight increase in mid-range power. The sound though is GLORIOUS! This is my 4th setup -- from JCR valved race pipes, to JCR straight race pipes, to Cargraphic valved side deletes with Akra slip on, to my current setup. This setup is loud but with ZERO drone! It gets real nasty >4k RPM. Here are some photos:












Now I have a set of German-made (Cargraphic) valved side deletes to unload. Bought them new for $2400, put about 200 miles on them, and they still look new. Willing to take a financial hit as I no longer have use for these -- please make me an offer if interested. Here are some photos:

 

Great choice! Are you running a .1 or .2 version of the RS?

 

Thanks! I have a 991.2

how do you like the akra muffler? i have full race header with valved deletes, stock center muffler. thinking about a center at some point, wonder if it sounds any differnt than the stock one?

 

Just had a set of Dundon street headers installed on my 991.2 GT3 last Friday. Nice bump in power and they sound fantastic. Took the tech at POV 1 1/2 hours to install them. Plug an play no hassle install.
NO drone!

 

I used an Akra slip-on center muffler on my 997.2 GT3 with stock cats and side mufflers. It was a tad louder than the OEM center muffler and had a higher tone. That’s what convinced me to go again with an Akra muffler on the RS. It is louder than stock, but not by much - and zero drone. Also, the aesthetic score on Akra products is off the charts - they’re made like jewelry!

 

Sound wise , which exhaust combo had the highest pitch ? And which was your favorate exhaust ?

 

Agree with plug and play, and no drone!

1.5 hours to install with a lift makes sense. i took my time with the 5 hour job on jack stands and was **** with everything — but removing rear wheels was probably overkill.

 

Looks great. I have the Akrapovic center as well with side deletes and it’s a great setup.

 

Wow, nice setup 👍 Am still waffling on the Dundon street headers with oem muffler, currently with Akra CMB, cant quite pull the trigger 😡

BTW, are u a 2-channel or home theater guy?

 

2 channel analog

 

in terms of sound tone, not withstanding drone, I would say JCR. I think Dundon with Akra will be on the RS for a long time.

 

Cargraphic side deletes have sold.

 

Akra, like the stock OEM Ti or Steel muffler isn’t recommended with Race headers.. The mufflers will crack...
