Catalytic Converter Poll

[hatrik8]

Which catalytic convert do you use? Mine makes a ticking noise when it gets heated up and needs replacing eventually. Any recommendations? I know no cat is bad for overboost.

I have a random tech, I snapped the exhaust bolt off in my stock cat otherwise I would still be using that.

I went with a Random 3" in/out. I cut the input flange off my ATR exhaust and welded a 3" to 3" adapter on in it's place, with standard clamp onto the cat. Have another adapter from the downpipe up to 3" inlet on the cat.

I went w/ ATR, I needed something quick to get through emissions.

In the last 3 Sy's I've been in, the exhaust system ended at the downpipe. :rotf:

These trucks were built with Cats??? j/k

Mine's been in the attic since 'bout '93.

My .02 - 3" Stainless Sewer Pipe from the turbo back and an External Wastegate is all I need.

Re: Catalytic Converter Poll

I thought no cat led to overboost problems? What do you guy recommend for a stock truck? Should I spend the extra and get a high flow cat or is it risky/not worth it? I have an ATR exhaust and open air filter with stock turbo.

Exhaust.................Cat............whats that?:dunno:
:lol: one of the first things i did was take my cat off and it made a hell of a difference,
I run a 35 degree down bend right off my dp and i love it! my truck sounds like a city bus when its rolling down the road

Re: Catalytic Converter Poll

is there a diffrence in a sy an ty cat? The reason i ask is that i purchased an atr cat, but it does not align to the back exhaust. It seems to me that the flange is welded upside or the holes where made in the wrong position.Could i have received a ty cat? I own a sy.
