Once i install my megan batch 4, i was thinking of adding a hi-flo cat....anyone seen good results from this??

 

I haven't heard of this(high flow cats) being done frequently, if at all, but I know it is a attribute the Type-S has and the Premium model lacks. I'm interested in this answer just as well.

I wana understand headers, what do they do. and how do they increase HP?

 

u could get a type-s cat.
i think it's bigger.

do a search.
it's been done.

 

VITEK, here you go... http://www.speedstash.com/infocenter...s_headers.html

I'll venture to say the Type S cat is hard to find and also it probably won't yeild much hp(I'm not saying it won't help, but probably minimally), thus making its cost benefit ratio not worth it. This is all speculation, I'm just trying to contribute.

typically now days unless you have a high mileage cat replacing it with a "high flo" wont yeild much if any hp

 

damn, i have heard that it makes a diff, even on my Type S

 

the whole point is our stock exhaust is pretty good and not very restrictive (other than the stock exhaust manafolds) - and it wont really help your gains to change the cat, or a new cat back exhaust unless you are running some sort of forced induction. because the v6 really doesnt produce that much exhaust, therefore it doesnt really need an ultra low restrictive exhaust.

 

Kris you probably have the highest number of miles piled on your 00 TLP, how is the cat holding up?

 

as far as i know just fine. no rattles (loose parts inside when taped on with mallet) or loss in power, or smell. Ive contimplated removing it and inspecting, but never have

 

how many miles are you pushin?

 

187,500 Miles

 

i bet for fsttyms1 and me close to 114k a new cat would help, but an OEM cat is expensive. aftermarket hi-flow cats, like magnaflow's are almost 1/3 of the price at around 200-300. I have a related question. after driving for a while when I hit 2500rpm's i hear a little resonance from my headers and then a rattling buzz, could that be a loose part inside or outside my cat?

 

holyshit how is she runnin

 

Fsttyms1...................... How the hell do you know so much?

 

?? im sure it probably would. (even though my car has only goten faster)

Great

By not being afraid to get dirty or break things and take things apart

 

There is no such thing as a high flow cat, just a bigger one. I am thinking about putting in a straight pipe. check out my thread to see what other peple have to say. our cars have a problem; in that they are so well deisned that it is hard to get big perfomance gains without shelling out some serious money.

 

i have a type-S cat and comptech cat back on my TL-P and it feels really good b4 and after

the flow is better and improved low-mid range response

acceleration wise it improved for the top end, hitting 145mph sooner than b4

 

Good setup , how much did you pay for an used Type-S cat? Thanks
