5.0L DI FILIPPO Exhaust System

[Emackulation]

Hey all,
After doing a but of searching around I didn't find any good threads about the gains of a DI FILIPPO exhaust system on a 5.0L, there are a few good comparisons with LS1's but im not satisfied to compare those 2 different engines.

I have been THINKING about what a full system would do to my car and how much it would pull after installation.

Also, if anyone has been through this before and knows prices, would be helpfull. I know if I want to get real serious I should ring them myself, but Im just putting this out there first.

How much $$$$$$$ do you have?

[Emackulation]

Say budget of 2.5-3k non fitted?

You won't have much change from that, trust me! I priced a complete system from them, exhaust ports to tip and non-fitted was around $2800.

Thats the type of info I was looking for, thanks Striker. Now, did you happen to get any power graphs or expected gain numbers from them?

Nope. To be honest I wouldn't use there headers. They are a 4-1 setup which only really suits a stroker or monster 304, that and they have some clearance issues.

Arn't most headers a 4 -1 setup? Well the higher performance headers atleast? What would you recommend, pacemakers?

All other companies make tri-y's for the 5.0lt, as this gives more low down torque.

[greenfoam]

They will out power pacemakers, it's hard to get information on them because not many people can afford them but the little bit I've heard is that they will put a stock statesman into a 14.5 second 1/4 and them make alot more low end torque than paceys as they should being 4-1s and that's what tuned length is all about. But the 3 inch ? collectors don't leave you much room for speed humps on a low car so it depends where you live if they are suitable.

I will say that even pacemaker build 4-1s when it's practical, but there's not alot of room on the VN-S's and tri-ys take less room, that's the only reason most companys only do them for the VN-S

[Emackulation]

Hmmm, Well my cars lowest point is the front bar, so I generally avoid speed bumps anyway. The town where I live shoudn't have many issues with scraping the collectors.

On another matter, is it a hate crime to put a full exhaust system on my GTS?

Why would it be a hate crime? The factory system is pretty woeful.

[1991_Vn2nV]

Nah man, but keep the stock setup just in case

Yeah I suppose it wouda been ok back in 1992. haha.

Nah man, but keep the stock setup just in case

Yeah, was planning on keeping it in the shed, just like my rear resonator.

FEED ME MORE INFO....please...

[nathans1987]

you could spend about a grand and get a system almost as good if they are better i doubt you would notice on a stock motor. then you could spend the other 2k+ on a cam or stroker kit or somthing and be well infront.

[Not_An_Abba_Fan]

Pacemaker do not make a tuned length extractor for any V8 from the VB to the VT 1 anyway. Difillipo's are good for what they are, but I doubt you will benefit from their performance on a stock 304.

Pacey PH5000D, dual outlet, twin cats and twin 2 1/2" system will be the best set up for your car. Or even a single 3" if you don't want it to bark. Going a high performance set up isn't worth the money you pay unless you have the engine to justify it. Apart from bragging rights, I wouldn't use any top shelf stuff at all when cheaper parts will work just as well or sometimes even better.

I like bragging rights, but then again I like saving money. I would rather stick to a twin 2.5" system, My car is stock, and will remain mostly stock too, I do intend on getting a tune and doing the exhaust along with freshening up the motor. I wish to keep this car as stock as possible.

So the argument is its not worth spending the big bucks on a Di Fillippo when my car wont use its full potential.

[Not_An_Abba_Fan]

Thats exactly right. Whats the point of having a whiz bang coffee machine that makes double decaf half caf espresso cappucino latte's when all you drink is flat white. And it won't give the desired output by driving it around on the street. The Difillipo system will have the goods to be tapped if you need it, but if you are not going to use that available flow, it will actually be detrimental.

Well heres and update, today I went to the 2 main exhaust shops in my town and got a quote for a twin 2.5" system.

All systems are mandrel bent.

Shop 1
Pacemaker PH5000D (ceramic coated) $957
2x High flow Cats $538
2x Front mufflers $200
1x Twin in Twin out Rear Muffler (resi) $130
10x 2.5" Bends $220
4x Flanges $44
Gaskets $30
Labour to make system x6(hours?) Fitting ext(extracors or whole system?) 2.5(hours?) $561

Total: $2680

Shop 2
Pacemaker PH5000D $890
Ceramic Coating $200
2x High flow Cats $560
Twin 2.5" System ABOUT $600
(I didnt ask for rear resi on this one)
Total: $2250

As you can see the 2nd shop didnt go into as much detail as the first, but the 1st was more expensive. I think the the 2nd (carline) will hit me up for some more cash for underquoting.

The other option is a bolt on 3" system....I didn't get any prices, but they said it would be quite a bit cheaper.

What do YOU think?

I've been thinking about getting a 3" system for a while. The full twin system is obviously going to be better, the question is whether it's going to represent good value.

[Not_An_Abba_Fan]

As an example, I do PH5000D ceramic for $900, and a 3" bolt on with one muffler and no rear resonator for $375. Cats are $260 each.

I'd definitely go with the first quote man... They seem to be more serious about the system as it is with the quote. Plus considering they are cheaper on the Headers and ceramic coating as well as the 2 high flow cats... I think you'll find some extra charges on the second quote. Twin 2.5" system for $600 including mufflers, bends, flanges, gaskets and labour? Does that quote actually include labour?

The first place took the time to give a proper quote, the second place just gave a rough estimate more than anything.

Grab a price on the 3" system and see what the difference is though... Then its up to you whether you're willing to spend the extra.

[minux]

Mate, call defilipo, what if down the track you decide on further internal mods, the defilipo system will cater nicely for it. I have used 2 different defilipo systems(admittedly on LS1's) and i was never happier, exhaust note was perfect, system look great.
