Just ordered a dundon street headers for my .2gt3. But still considering if I should get their Black loud muffler as well.
From your current setup, with dundon header itself can you feel how much louder than stock header from outside the car?
If it's under 20% gain from outside, I probably will get black muffler for more gain. But it's kind of pricy for the muffler.

You can always add the Black Muffler later. See how it sounds and if you like it w/o it

Just be aware that if you buy the system set up for stock center muffler, the lower muffler intake pipe is smaller diameter than if you buy it to match the Dundon center muffler (2.5" vs 3").

So you mean side muffler delete is different for stock center muffler and Dundon center muffler?
I didnt noticed that before. Because when I order the headers there is no option to choose side delete diameters.

Will the full Dundon system drone?

We specify the diameter based on what is ordered. If the headers are for our muffler we do 3” the entire way. If the headers/side deletes are for a stock muffler we step them down to 2.5”.

So if you order a street header kit and a lifetime muffler from us at the same time it will come 3”.

If you only order headers they will come stepped down to 2.5” for the stock muffler

No our systems do not drone, that is the point of including valves and a center muffler.

Typically 2 weeks. Have been a few delays recently with loud mufflers. But we’re getting things out pretty quickly lately

Best way to get info on your order is to write us an email. Asking in a rennlist post is a little bit indirect....
