Had the Steeda Cold Air Kit part # 555-3162 installed with a tune the numbers were 410 to the tires and 340 torque, the baseline numbers in stock form were 384 and 314 torque, very happy with the results.

Thats what I would do if I didnt have a warranty. I will do it one day when the warranty is gone. by then gas might be 8 bucks a gallon loladam81 said:For the Boss, without getting crazy, I think there is a decent amount of power to be made with a CAI, headers, no cats, and a tune. I think you can get 50-60whp out of it..... These motors by design just don't make a lot of torque so I think 30-40 wtq is reasonable there.
For the Boss all that is about $2k and you wouldn't need to do anything more for engine mods. Unless of course you wanted to do cams, heads, lower end work....
So what would your mods be?PeteInCT said:How much do you think I could get from removing the cats and going to a Corsa exhaust (if the exhaust has any gains associated with it at all ? Assume no tune/headers and my Airaid intake...
Not enough to warrant the removal of the cats. I would say 10rwhp +-2 take out the cats get another 2 or 3 hpPeteInCT said:Only remval of cats, Corsa exhaust and my existing Airaid CAI. No headers, no tune.
According to these results, it's more like 22 rwhp and 23 rwtq from removing the cats. In fact, most of the gains are from removing the cats, which would require a tune to shut off the rear O2s or you'll have a CEL.boss2511 said:Not enough to warrant the removal of the cats.

Just my guess from what I have read in magazines so take that for what it is worth
He doesnt want to run headers.....that is where the power is coming from. Stock manifolds removing the cats...with what I presume to be a off road h-pipe say it is a full 3" mid pipe than maybe its worth 10rwhp in itself. if just removing them and puting the 2.75" back in its place it isnt worth much.cloud9 said:According to these results, it's more like 22 rwhp and 23 rwtq from removing the cats.

I talked to Shaun at AED at length about this last weekend. He says there's very close to a 20 HP gain by removing the cats with an H pipe. Opening up the side exhaust and free flowing axelbacks is good for 3-7 depending on who you talk to. I have no idea how the two combined work but I think your good for 20 HP. Your Airaid CAI with the sleeve might add 1-2 HP if you're lucky.PeteInCT said:How much do you think I could get from removing the cats and going to a Corsa exhaust (if the exhaust has any gains associated with it at all ?

I'm sure you know this but our cars don't have exhaust manifolds they have shorty tube headers, the same ones on the 5.0's, 302S and 302R.boss2511 said:He doesnt want to run headers.....that is where the power is coming from.
