Went around to a couple muffler shops today, and am fiddling around with the idea of putting headers and a full system on my truck. The question is... is it worth it. I can put a cat back system in for about $350, where a full system is around $600 plus the price of the headers. I heard not to mess around with the O2 sensors, but one installer said as long as they are in the right place, it won't matter. Is there a whole bunch of difference between the two? I also still can not find a decent Cat-back system for my truck!! 2005 extended cab long bed built in 04/05. Your advice is welcomed and cherished. Thank you.
p.s. I am not looking just for a louder truck. This is my daily driver and I tow a 7000 lb camper with it. I want power over sound

 

Did you have the 4.10's installed?

 

No, the gearing came from the factory like that

 

I'd go full system if money is not an option, you'll be much happier.

Its a 7-lug.

 

It's really an issue of performance/cost for me as to whether or not I modify my truck with a particular part.

If money was no object I would already have headers. And exhaust. And a supercharger. and fans. and wheels. and tires. and racing stripes. and a suspension package. and and and and....oh man. Now you've got me all hot and bothered.

If you can do it might as well go for the gold. Besides with just a cat back you really aren't going to feel that much of a difference.

 

with stock motor your not going to feel THAT much of a difference with full exhaust. IF you are definately planning on installing a s/c I would install a full exhaust system in a blink of an eye. However if your just going to do minor bolt-ons, well there is pretty much no difference in either set-up performance wise. The biggest difference is sound. magnaflow's cat-backs get positive gains on the dyno. I say for what your saying your best off to go with a cat-back.

 

my big issue is that I can't seem to find a decent system for my truck. Companies aren't making exhaust for the extended cab long bed. I can get a guy to fab up a system using whatever muffler I want, but he does not have a mandrel bender. He says his bender doesn't crimp the pipe but it does narrow it through the bend.

 

I think a flowmaster system will work, but I am not sure of their quality. I also am not looking for a super loud system.

 

Get 2 high flow cats, magnaflow muffler and headers if u really want them, this is the best way to get power.

 

What about blowing gaskets? I am using this for an everyday driver and I do not want to be replacing gaskets all the time
