So I made an exhaust change. Here's the set-up before: LPP headers, custom 3 inch H pipe, 2 x 18 inch dynomax bullets with turndowns



Inside the car with the windows up

Outside the car

Walk around

New setup: Same headers, 3 inch into a flowmaster merge, then 1 single 4 inch going into a single chamber delta force Flowmaster with a single turndown.

Pics first:

Started with this






The workhorse for the job


Starting to mock up

I originally was gonna have the exhaust dump out towards the back of the rear tire like this but it didn't work out that way in the end.


This is what I had to do to the rear floorboard


Muffler was almost dragging the ground so I realized more work was needed


Here is the muffler in a better position, and now a new floor needs to be made and sealed up.


Here is the mock up panels tacked in place.



Finished product


Here's what it sounds like

Idle walkaround

Part throttle, keep in mind I have a 4000 converter

WOT from second and going into 3rd

Thoughts and opinions are always welcome

 

don't you lose power air to pistons ,I know with me new set up ,I need true duals to let the puppies breath,though your doing something right to get it running 11s ,how much you spending ?

 

A single 4 flows pretty close to 2x3s so that wasn't a big issue.

 

I see ,it has 2 inlets 2 outlets I have considered that ,but I got 2 flow masters .yes I will find out soon if I got clearance issues
