ART PIPES VS LTH (F.I or PPE)

indyn

Planning to get either the ART pipes or the Long tube headers. I've done the search but couldn't find an answer to my question, which one nets more gains?

LTH's and TP will fail for emissions but my car won't be tested for another two years, but its easier to swap the TP's than LTHs.

What would be the best setup.
1.Stock with ART
2.Shorty header(like STillen) with ART
3. F.I. LTH
4. PPE LTH

theDreamer

Best gains will be LTHs

If you plan on swapping back to stock/legal for emissions testing, I wouldn't do LTH. The install/removal on LTH is pretty intensive work. Test pipes and cats are far easier to swap around.

I don't know that the headers are worth that much money for the extra hp you gain with a CBE already installed... i've never seen the numbers anyway. That said, I don't know how much hp you gain with ART pipes installed with a CBE either. I'm getting the ART pipes in a few days and installing them as my first mod. I may later get some stillen headers so I can still change out to the cats when emissions time comes around in 2 years.

Short headers by themselves do not provide much of a documented gain, combined with other upgrades are worth it. Yet then you are at the point of just going LTH which show large gains, but of course emissions is a concern.

LTH's will most probably be the best gains. theDreamer has a set for sale as well

Go LTH's other than the install which is a bitch they are hands down the best bang for the buck especially if you plan on staying naturally aspirated.

I heard that stillen's didn't have a very large gain... naturally the LT's are going to have more because they are a header and TP all in one basically... if Stillen's with a set of ART pipes on a stock set-up were tested, you might the comparable gains.

theDreamer

Re-read what I said.
Also, LTH v. other options have been done and the LTH still have larger gains.

Motordyne will give you a good discount on a set of ART pipes if you can do a dyno comparison of them against LTH's and post your results here.

I love my long FI long tubes the labor is high to have them installed. Many shops don't want to install them

In NJ new car don't need emission test till 5 years after purchase. Sooo not worrying about it yet

Installation time and cost should be same with either lth or Shorty Header. Stillen does free some HP, plus add the ART pipes should net almost same as LTH or little less?!
But I think with any test pipe its easier to swap back to HFC or stock cats when its emissions time.
Is it possible to add a catalytic converter with a LTH setup in the front or mid pipe sections of the exhaust, this way I can add the cats right before emission testing. It'll cost money but I get to use LTH's.

theDreamer: do you still have your LTH?
Motorydyne ; send me the discounted price.

theDreamer

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.

You could do the 2 into 1 XYZ pipe with HFC. I think the part of the mid pipe is interchangable between straight pipe, HFC and resonated straight pipe. Would be easier to swap out than the stock cat location.
