I have a crack in my header. I could weld it but I'm just gonna replace the entire exhaust. Could someone make this real easy for me and list the size of everything I'm going to need? Thanks guys!

 

heres what im running:

NAPA fel-pro combination gasket
APN header
Walker down pipe(no dent)
magnaflow cat
flowmaster 40 sereies muffler
rustys 2.5 mandrel bent tail pipe
NTK oxygen sensors

 

If you are replacing everything do 2.5 in. The whole way through.

 

double post

 

I have a APN Header (Just got it yesterday so its not installed yet )

What is currently installed :

Custom 2.5" Bent Downpipe (Stock Manifold to Cat.)
2.5" Hiflow Thunderbolt Spun Cat (From Perfomance-Curve.net ...... AKA Mudfrog , A Vendor on here)
2.5" Magnaflow Muffler (18" Body) I went with a 4" round body magnaflow on mine so I can tuck it tighter and for a more agressive sound
2.5" Mandrel bent tailpipe from Performance-Curve.net


Performance curve offers 2.5" catbacks for $100 with a choice of Flowmaster or Magnaflow Mufflers


Here's some pics and Videos of my Exhaust still with stock manifold (Sounds closest to life like with Headphones) :









After Ceramic coating :

 

Where did you get your down pipe?

 

It was custom bent by the exhaust shop that welded up everything it cost about $90 for them to bend it up and 100 to weld up the entire exhaust

 

Bump everything up to 2.5" pipe. High flow Thunderbolt cat from performance curve, and look at their generic mufflers too. I actually like mine a lot, though it's a single chambered muffler.

I used an Iphone in this video, it's not really that raspy


Look around on YouTube and listen to a few different set-ups, you'll find something good.
