ok sounds good let me score some cash and ill let u know

 

This car is KAGE on these forums I believe. He has K&N drop in filter, and Hahn 3" Catback.



And here is a RWD Sky that I tuned the same day:

 

damn! I need to get a copy of HPT this week!

 

im off tues thurs fri sat and sun this coming week, let me know when you want to try it out

 

I'll be in town all next weekend. I have a few cars to tune but I can fit you in on Friday night.

 

You got the name right, Thank You for coming out and working your magic.

 

i thought you got those numbers out of stock cobalt lol i guess not

 

The catback means nothing really.

Mainly sound

 

i think our cats are pretty restricted if u seen a picture of one that was posted

 

you can only cram so much air through a pixie straw

 

You mean my thread?

Yeah.

Yeah I agree, but apparently at the power levels, the stock does just fine.

Synapse did dyno runs with no cat back hooked up and gained nothing.

 

your saying with a k&n filter and a aftermarket cat there is no gain

 

does the sky have the catback and drop in too?

 

Catback made no difference he baselined same as everyone else.

the sky was bone stock not even a drop in.

 

so basically the exhaust and intake combo did nothing? that kinda blows lol maybe if the downpipe was upgraded it would do more

 

only mod to date I have seen make a difference is the charge pipes on the sky/solstice. And it didn't make more power it just maintained peak HP longer. When you see their stock pipes there's no question why.

yup intakes have been making no difference either. I have a highflow cat in my possession I will be testing soon.

 

Thanks again Steve it was a pleasure and we will def have to do it again. If you think people will get off your ass post my results because other than a kn drop in I am bone stock and only a couple hp lower.

 

yeah defenitley let us know how the high flow cat test goes

 

Even if there was a single cat DP there would without a doubt be gains.

Either way, any change of cats is illegal...I don't get why people want a catted exhaust still...a catless LNF is still mad quiet.

 

I hate cats, I prefer to go "all natural"

 

I am going to cry come inspection time and I have to put the stocker back on for 15 minutes

 

^^ ditto

 

psh get a slip on cat lookalike lol

 

There's something called a "sniff test" that some states do also good thing I have a place that I can just go and get a slip saying I passed without them even looking lol

 

Sniff tests in most states are done for obd1 and earlier vehicles.
