4GEN Liberty and Legacy 3.0 Exhaust headers

[dlee]

any recommendations on what cats to use? and how much should a exhaust shop charge for this sort of job?

For yours, pair of high flow 100 cell cats for around $150-$200 each then say $200 for pipework and labour

I bought 2.25" 100cell BOKKA cats. Hopefully they're not rubbish.
Zorst shop quoted ~ $300-$350 to install my headers, cats & 3rd cat delete 2-1 mod.


Still trying to decide whether to go 2.5" pipe from the cats (or even the 2-1 join), to the stock resonator (flange), or keep all pipes the stock 2.25" size. My aim is maximum mid range torque rather than top-end. Stock resonator-back for the foreseeable future. Money! And I hate to say it, but I'm 90% sure this car will never be supercharged -unfortunately..
KiDo, E85, the upcoming CAI, & these headers will round out the engine mods.
Any advice would be welcome.

any argument to go for 100cpi instead of 200cpi?

am taking a lot of this advice in so much thanks to those in the know contributing, especially those like Tim, Edward, Matt and many others that have a wealth of knowledge, definitely shaping many H6's systems around the country/world

The boat was scheduled to dock at 2:30am this morning - and that's not even an April fools Joke lol

Just a matter of paperwork and some freight and hopefully I soon have the goods

This from my customs agent today

It usually takes about a week for the container to be transported to the depot and unpacked. So it could possibly become available late this week, but more likely early next week.

Have your money ready - I believe these stock order could be gone quick

I will release them in batches of 10 so that i can realistically get them all shipped and to customers in 4-5 working days. Dont worry if you miss the first batch, will be immediately followed by a second batch.

Yes - everyone is free to add CAT BACK suggestions in this thread if they have experienced good product- I would ask that you indicate whether or not the Catback you are talking about has increased drone in the car interior - I hate drone and I reckon plenty other people do too

[nhimsta]

Yes has increased drone inside car but very tolerable .....will see what the difference headers and high flow cats make ...have kept,resonator ...just in case but suspect it will be fine , actually hearing the engine has helped for,those over-revving moments I suffered when I couldn't hear the engine ......

I am still contemplating the ss xforce cat back but welding the original centre pipe resonator back into it to eliminate noise as I have heard the stock resonator is reasonably good for flow

started off with ultrex mufflers - little drone, 20-30% louder

added xforce stainless steel center & y pipe to ultrex mufflers - quite a lot of drone, pretty loud

removed ultrex mufflers, added STI mufflers to the xforce system - no drone (virtually like stock), only loud when you give it the beans.

so damn happy with the current setup.

Exactly my setup. Bloody love it.

I'm mainly concerned about the 2800 - 3200 rpm range in 6th sitting on 130 - 140kmph cruisin as I do this for around 3 hours or so to Darwin. I hear this is the main drone range so this is my concern and the only half decent muffler shop is in Darwin around 350km away so its not as though I can keep running backwards and forwards
