ART PIPES VS LTH (F.I or PPE)

ChrisSlicks

BTW just ordered the ART pipes today, and just got a message saying they will ship today. Great service!

Tony,
You don't seem to have a bung for the o2 sensor in the XYZ pipe, can you get by without placing it after HFC? And do the ART pipes attach to the factory exhaust mounting bracket?

Motordyne

There is no bung on the XYZ. Its not needed if you have ART pipes where they have the bung/non-fowler built in. With the CEL kept off, there is no need for additional bungs unless you have some kind of special set up like what is typically seen with forced induction systems.

I still have my LTH, a few people have been interested but no one has bought them.

I wish I had the money to spare and make a comparasion between my PPE and those FI LTH !
my bet would go for PPE but no one ever did the test but knowing the advantage on the steped header , I went with PPE.

I would definitely do Art pipes if I was in your position. They will take an hour or so to remove and replace with stock cats for emissions versus many many hours and a complex installation process for long tube headers. From least amount of power to most amount of power, this is what I think:

stock cats < high flow cats < test pipes < Art pipes < LTHs.

Or for torque:

Stock cats < test pipes < high flow cats < Art pipes < LTHs

However, you have to realize that the difference between Art pipes and LTHs will be a few wheel horsepower at most.

all you're doing is trying to put a plug in to sell your LTH's.. why are you selling them if they put out such good gains exactly?

theDreamer

Plug for my headers, I was not the one who mentioned my sale. People can find them in the FS thread on their own if they want them.
Why I am changing? I have a SC and they work fantastically, but I am moving towards something more than just gains as I always have. Balance is key with my car, now just in weight or power but also sound and style. It all has to work together to achieve what I want. Power is only a small percentage of what one can do to a car.

What are you currently using in the location for the stock cats? Stock cats, HFC's or test pipes?

theDreamer

Currently I am o stock header/cats as I decide what I plan to do. I am thinking a RTP with stock headers and maybe a whole new exhaust.

Another factor to think about: You can get away with running the stock ECU tune with most simple bolt-ons (e.g. HFCs, etc), but a full set of intake/exhaust boltons including LTH pretty much requires a dyno tune. I know because I'm running LTH on my stock tune right now (temporarily), and the bottom end of the rev range is horrid once the engine is heat-soaked, it's worse than stock

Stay in touch as you change your setup or plan to make changes. Particularly if you change the whole exhaust too. I'll have something very interesting for you to dyno test with your SC.

indyn

all great suggestions guys. Wish had the money and time to do all comparisions but leaning towards Stock/Stillen header plus ART.

Motordyne

I can understand that. It would actually be a big project to do such a comparison and its not exactly something most people would have the time for.

I'll leave this open to anyone interested in doing such a comparison. It would make a valuable comparative data point for the community.

Methodical4u

agree there... but headers will probably be the last mod I do... it's going to be to install the ART pipes, and then buy and install the XYZ pipe and then get a CBE. Then intakes... Perhaps Tony you all may have your intake finished or close to it?

By the way Tony, I was wondering... if I don't want a loud exhaust... and since the ART pipes obviously are not a hfc... would I be better with the XYZ with HFC or resonated? I guess resonated since I could always put my OE cats back on right?
