340 headers VF2

[MY17DIR]

I fitted pacemaker 5387's and had them linked too a gts 2.5" cat back.

Cost for pipework / magnaflow 200cell 30deg angled cats $800. Similar sort of work if you do This with the 340 headers. Then you'll need a tune.

Looks like some quality workmanship there, nice job.

Looks vaguely familiar
Mainly different collector -> longer and mandrel megaphone 46ci, and cat position -> after the trans mount.
View media item 493What do you mean 30° angled cats?
Did you specify the dimensions or let shop fit it best?

Wished we had some one in Sydney that would take the time to do that neat a job,every one I speak to aren’t interested to do stuff like that or find it to hard,probably beyond their skills,I wanted very similar to what Mike_ has but no one would listen to me so I will probably just go Hurricane 4-1s to same the time.

The bloke who runs Sureflo over there has a really good technical knowledge and does both off-the-shelf and custom work.
I recommend Pipemax software to understand and plan the exercise so you know what you want as opposed to having an exhaust shop "fit" some components in. I learned quite a bit by spending quite a lot, perhaps worth reading these few posts if you are interested in performance tuning the engine.

Liverpool Exhaust do a fair bit of custom work, so I'm surprised they won't come to the party

Thanks for the info Monstar,these few posts were very good reading I some how missed those posts,full of good info.

Yes Steve is great with all things LS, one of the few who has a dyno for before & after results.

Yeh I seem to recall that photo posted
by someone who keeps preaching the 5387 + pipe combo on here. verified by my cousins hubbie who also uses pipemax software for his sports sedan exhaust setup and told me to use the Pacey 5387's a while back.

There wasn't much science in my approach, it's the family hauler not a race car but may aswell try get it close to what theory suggests whilst still being practical. Don't plan on doing this exercise a 2nd time.

I specified to Dominic over the phone beforehand what I wanted done for a ball park cost. He's familiar with the cars and the gts 2.5" mid section. I had a rough idea of measurements before fitting the headers over the weekend and seeing him on the Monday.

With the car up on the hoist @ the prestige workshop a ~200mm collector seemed like it would work with a 8" cat following the original exhaust path Whilst retaining the oem / gts 2.5" hanger points and exhaust route path. The result what they came up with was what I had visualised and but not sure how it would be executed. Your pipe work has the hangers on the opposite side and looks to follow a new path.

Dom used magnaflow 3" 200cell cats with a 30deg entry angle. He had a choice of straight or 30deg entry angle . I googled and only came up with straight entry so I'm not sure if maybe the small entry was cut on an angle before install?

I took 2 small clips I still need to upload if anyone is interested. Nothing special but sounds fine to me

These guys do a lot of hot rod work and did all the pipework on a family members chev belair? He commonly uses the same setup Naaf recommends on these cars. I'll agree not many exhaust shops do work like this. I had a local business make an absolute mess out of a simple job installing my gts mid section. Photos on here somewhere from last year.
