Can this only be installed with with the Dundon side delete or street headers, or can it be installed with stock headers/side mufflers? From their product description I can't tell, but I thought it was supposed to be an incremental part where you could start with it and then add more if you wanted more volume.

Mini Crack works with stock side mufflers as well as our Street Headers. Feel free to give us a call with any questions :-)

Thanks!

Any chance you have a sound clip of it without headers? I can’t find one.

Ted@dundonmotorsports

I've never run one with stock side mufflers (many of our customers have, I've just never done one in house). It will be pretty quiet with valves closed, but valves open will be rather raucous.

I have the street headers and loud lifetime muffler. I feel this is the best combo for street sound set up.

If you are running the stock side mullfer and the mini crack pipe, does that mean you have to install the 2.5" mini instead of the 3"?

gravedgr

That sounds like exactly what I'm looking for.

The car is pretty loud now, so I'm sure you mean "pretty quiet" is relative.

Why did you go this particular route, @BergGt3 ? I don't care about any power increases, I just want the high pitched RSR scream at upper RPMs.

BergGt3

No drone. Good pitch. Loud enough but not stupid

Shot this video last weekend. Shoot me a pm if interested in set up.

These cars sound awesome…😀

gravedgr

Sounds good, what are you running?

I just got the car and after a year with my 570 I’m having to re-adjust how I expect it to act and sound, so I’m not in a rush.

Ted@dundonmotorsports

Correct. The stock side mufflers have 2.5" lower outlets, so you need the matching inlet size on the mini crack. Our Street Headers come in 2.5" and 3.0", so we make both sizes.

this is the same set up I have, its high quality, lot lighter, sounds is awesome. better to go with the entire set up, if you buy pieces to work with OEM you then are stuck with the 2.5" vs 3" with the full Dundon set up - I am not sure how this affects the power gains?

Ted@dundonmotorsports

On an otherwise stock car, power difference is trivial between 2.5" and 3.0". With our intake kit (especially on longer track session) the 3.0" setup's ability to evacuate heat is a big advantage (and why we built the 3.0" system to begin with).

For cars that don't see much track use or aren't going to add the intake side of things the 2.5" is fine.

Is there any significant drone difference between street headers and loud muffler vs the mini crack pipe? I would like to get the higher pitch RSR sound and the performance gain. I do track my car. My current setup is the Soul center delete but they don't sell headers with cats.
