i already know about the rightup but what do you guys think about it?

 

[thestoprule]

makes it louder.. like a little "raspy" sound to it

 

[thestoprule]

:yeahthat: or check this out...
i dont have any cats, just a flowmaster super 40

anybody w/ no cats?

 

[94racing]

so probably over a 20 hp gain AT 5500 rpm

 

[94racing]

so the cats are gutted and you have flowmaster super fourtys on it?

 

[ZNA03]

I never felt much of a power gain... i'm sure its there but it probably didn't show as much with my truck and it's high milage.

 

[94racing]

huh did it gain any milage realy?

 

[Sharpeye]

Definate improvement in hp. It sounds slightly louder with a stock muffler.

 

[94racing]

thats what im going to do then cause it cant void warranty (cause i dont have any) and it doesnt get too extremely lowd. does it increase mpg though?

 

[rangerbob]

Same way every other exhaust mod does - less restriction.

 

[94racing]

thats what i thought. thanks ill do this when it warms up. this will be entertaining

 

[thestoprule]

first cat is gutted... second cat is completely replaced with pipe

 

[94racing]

so is that the stock exhaust system on it with modifications?

 

[thestoprule]

only mod to the exhaust... (besides gutting the first cat, deleting the second) is the flowmaster

 

[94racing]

ok got it. im just going to gut the first cat then

 

[*!*zero*!*]

i did this mod too. definetly makes the sound a bit louder. i noticed a slight increase in the but dyno, but nothing major. all in all its a free and easy mod to do, with great benifits, especialy if u have a tunner available.

 

[DrNota]

ill probably gut mine once my nitrous kit goes in

I'm going to finally get this done on leave when i get back from Iraq. I'm going to order another cat tho. In Maryland we have to do emissions, so to be on the safe side I still want to have a legal cat.

Does anyone have a link for news cats? I remember someone on here bought another new one, but can't remember who and how much.

Also, does anyone know how much it would cost to get one Jet coated?
