Dynojets are the most comparable across dynos (not necessarily more accurate) because they have fixed atmospheric correction factors (STD, SAE). All the others are variable unless you calibrate them to Dynojets. Dyno Dynamics, DynaPack, Mustang, can all be adjusted to read higher or lower with "bogus" (or fairly accurate) atmospheric correction factors (usually in an attempt to be on par with a DJ across town). The point is that if you don't get a Dynojet, it means nothing on this forum. It's still a great tuning tool and just fine though for a before/after comparison!

Well done.......dynojets are generally the easiest in comparative terms. My car is tuned on a dynodynamics, but I have a dynojet 1.5 miles from my house. I usually throw it on there for the ease of comparison.

Just out of curiosity were the numbers std or sae?

edit: good point seeing as Dynojet is globally accepted as the standard.

I just bought mine from Stillen. 304 stainless headers and Cats came to around $1,300 when all was said and done (CDN $). I can tell you that the car really pulls well now, much better then without the headers/cats. Netted approximately 15 whp. I feel that headers/cats are an excellent modification for the money.

Defin worth the cash! I'd like to compare TP's soon. Only reason i didn't go that route is fear of failing inspections. I don't know any shops willing to risk thier necks to hook a brother up with a sticker!

I am willing to bet that most of that power was gained via the HFC's. Headers are not worth the expense in my mind.

Not to sure where you're getting your numbers from but I'm of the mind that every hp I can squeeze out of it is valuable. Headers and cats are worth it.

If you think $1,300 for 15whp is pricey wait till you see what I have to pay for the next NA 15whp
