catalytic converter?

[78cj5Guy]

Anyone on here I can pay to gut my catalytic converters 03 chevy avalanche 1500 Z71 1 is going bad so just want to gut them because new once are $500

You can fit universals in place of the old units. I wouldn't recommend cleaning them out due to cel issues

 

[benXJ]

Haha. What?

Just pay a exhaust shop to install universal fits that are the correct inlet and exit size of the current exhaust system.

Public forum.

Violators are subject to civil penalties up to $37,500 per noncompliant vehicle or engine, $3,750 per tampering event or sale of defeat device, and $37,500 per day for reporting and recordkeeping violations. 42 U.S.C. § 7524; 40 C.F.R. § 19.4. The EPA often uses the Mobile Source Civil Penalty Policy to arrive at an appropriate civil penalty for vehicle and engine enforcement settlements.

Why not have a shop replace it with a universal version? Would be much cheaper

Cause I want hightflow cats or no cats and I am having a hard time finding highflow cats for a 03 Chevy 1500 if you can find some send me the links to em

For the fourth time...get some universal ones and weld them in. It's really simple. I think the ones I got were like 75 bucks a piece. High flow doesn't really matter...a cat might rob 5 horsepower.

X2. I would think any exhaust shop would do it for $100 or so if you took them the right parts.

If you are already straight piped any cat will help. You will literally be helping your truck running that little bit of restriction.

 

[Bogleparsons]

It's a TRAP!

 

[CasterTroy]

Yeah somebody PM him and bring him up to speed

increasing exhaust flow on a stock engine (bigger piping, straight pipe, headers) is all pointless unless you are also increasing air input with a cam, turbo, supercharger, etc.

your goal for a "high flow" is fruitless. if it is clogged just replace with a universal and stay legal.

That depends what kind of sticker it comes with.

Cadillac convertible?

i literally had a convo with the woman about this in the car the other day. "i thought i was a cadillac convertor???" lmao

 

[78cj5Guy]

Ok will see what I can find then I was trying to spend as little as I could it's my wife's truck my jeep is broke right now so we are sharing it

 

[a_kelley]

Universal aftermarket is like 80 @ advance

I did some experiments back in the late nineties with my very modded 94 z28. I created a flanged fore and aft mount for my cat and made a test pipe with the same flanges. This car ran mid 7s in the eighth which was pretty quick back then for an LT1 car.

There was on average, over the course of several sessions of switching back and forth, less than 1/2 a tenth difference. On a stock veh, it would be zero.

This was a stock GM cat, not a "hi-flow" model.

What makes you think anything is wrong with current cats?

What are you going to do about legality and liability for any shop to remove or gut them?

What are you going to do about inspections?

What are you going to do about the check engine light that will light with cat removal?

 

[a_kelley]

If you really want to spend as little as possible, just run it or fix it yourself. I've only ever seen a few converters melt and I'm pretty sure they were dumping fuel in the intake. P0420 below efficiency code simply means it's not doing a good enough job filtering emissions, not that it's hurting performance in most cases.

 

[ponykilr]

I think the OP wants it to be as loud as possible. It's the only answer.

 

[Mac5005]

Good thing the sheriff in my county had a press release about cracking down on loud exhaust and improper equip,met due to constituents' complaints.....

Dale Earnhardt didn't run no Cadillac Converter on his car
