Good Cat/Bad Cat

[Paradog]

Wondering...with all this talk of exhaust changes...there has been no mention of replacing the cat with a less restictive one. Has this been evaluated that the stock cat is good? Or is the replacement of the cat a big PIA?

Yes another n00b question from a wantabe motorhead!

Hi Paradog!

Take a look at the following article. It's from a post I did a few months ago. It should answer at least some of you questions regarding stock vs. performance exhaust systems:

I will have to check this out myself as I am changing my stock exhaust out soon. Nice rims, make that awesome rims...My 9yr old son wants me to get hooked up with 5 spoke chrome rims.

Nice article but I'm still confused.

Do I need to replaced the Charger's Cat if I mod the exhaust?

Maybe it's best to define what a cat back exhaust system is:

It is every from the Catalytic Converter back to the exhaust tip, hence "cat back".

An entire system replaces everything including the pipes. Stock pipe are "crush" bent meaning they do not carry the same diameter through the entire pipe, especially at the points where the pipe bends. Performance systems use mandrel bent pipes (even diameter throughout). This improves airflow and reduces back pressure on the engine.

You can replace as much, or as little of the existing system as you like. You can get just a performance muffler, exhaust tips, or just pipes. Although most folksw opt to replace the entire system.

I had to replace everything when I changed mine, as the factory had spot welded everything together. I could have had the installers cut everthing into parts, but I didn't think it was worth it.

Hope I am I getting closer to answering your question :happy:

If, however, you are asking if you need to replace the Catalytic converter in order to mod the rest of the exhaust......The answer would be NO!

Ah... you are a God!

I will now meditate on these words of wisdom you have shared with me! :wink:

Light Just went on!

So if I wanted to make the SXT a true dual I would have to buy a Y pipe after the cat and then run the rest accordingly.... any suggestions on cat manufacturers?

Hi & Thanks!

They are Zinik Z5 Ikeda 18" Wheels. I think they also come in 20" & 22" versions.

If you want a true dual system you only have one option at the moment.......Zoomers.

Actually, you have 2 Catalytic converters (one for each head unit). Zoomers would include an "X" pipe so there would be one independent exaust system for each engine head.

The only V6 owners that I know of who have the true Zoomers duals are Viper (who has had them for about a month), and rougewelder who just ordered his.

I have been running the Mopar cat-back dual system for about a month now and have been satisfied with the added performance & sound. The stock system uses 2 cats as spoonerock noted and connects them to a single muffler with a "Y" pipe. The Mopar system replaces the "Y" pipe with one with a larger outlet. This connects to a single 21/2" in, single 21/2" out muffler which hooks to another "Y" pipe than to 2 2" pipes to the resonators & tips. This system is all S/S and is made for Mopar by Borla. The muffler and resonators are all stright thru high flow design. It also comes with all parts for conversion, which on my SXT took the muffler shop about 1 hour. Hope this helps a little. :wave:

i stoped at a dealer in san diego california, and they had the mopar dual catback... 429 dollars... plus 230 for instalation... is that the one you got?? i think the instalation is a little high....

[charger Bill]

That was the system I got but my dealership gave me a 10% discount. You might see if you can get the place you went to match this. The installation cost sounds too high. Like I said all the parts needed to install are in the kit and it's just unbolt old system and bolt in new one. If the dealer won't budge on cost, check with a muffler shop. The new system comes in a pretty good size box so you might need at least a small truck , van or SUV to move. I have seen them advertised on the internet for about $385.00 but you would probable have to pay shipping but you might look into this. :happy:
