ok guys i have a clogged cat... now i have vibrant header/dp combo... should i just gut the cat and run catless??? these are my engine mods... stg 2, 2.9 pully, gm tune, vibrant header/dp, hahn 3" catback, RAW intake,ZZP heat exchanger... I dont know what to do!!!

 

just gut the cat

or

go to autozone and pick up some pipe and have it welded in to replace the cat...

or

pick up a small resonator of the same diameter and run that instead of the cat.

 

get a new tune

 

which do u suggest steven?

 

put a res in place of the cat. so u can keep the rasp and sound down a lil bit

 

what brand res should i get??

 

doesnt matter. a well known for quality atleast that way u know its legit and good. common sense ya know. would u rather have a guy new to mechanics work on ur car or say, hahn?? lol know what i mean?

 

true true... do they make small resonators?

 

idk. go to our vendor websites and look. or jcwhittney.com or summitracing.com ur pick. u kno wut ur looking for. or go to the exhaust place. they usually have them on hand.

 

The glasspack resonator is usually the one exhaust shops have on hand.

It's quality, and cheap.

 

Dood... just ditch the cat and get a good tune... you'll regret it. Trust me!

 

i just replaced mine with a some tube yesterday and added a mangaflow muffler it sounds like a pissed off chainsaw

 

ZZP's whisper resonator is a nice piece.

 

i just went catless and i love it... exhaust is a lil raspy but oh well

i have so much more power

 

frees it up a bit doesn't it...

id look into tuning the car

 

yeah i am but im in a rut cuz i dont wanna buy a wideband...

 

def. purchase one if you plan on tuning your car.

 

you think you do

 

He's on a GM stg2 tune with COT enabled.

Disabling COT entirely, can lean you out almost a whole point.

In his case, I'm sure he feels a slight power gain, it's not anything significant.

 

cot?? or am i just having a brain fart

 

CAT OVER TEMP

it dumps fuel once the set temperature threshhold is met to lower EGTs.

Messes with your fueling

Something along those lines

 

mine was bone stock and still melted

 

your right cole i know i have no real gain... but i like the way it sounds lol

hey cole do u only have the plx wideband?

 

what do you mean only? like, do i have another wideband?

 

yeah...
