97 Tahoe Muffler

[BiggWaukegan]

About to get the Tahoe some new muffler work. Just wondering, a few people have recommended Dynoflow or something like that for exhaust pipes? Ring a bell to anyone? and are they worth it?

I have a Dynomax muffler on my 95 2-door. I originally had a single in single out Flowmaster. I changed basically because i wanted a different sound. Everyone where i live has Flowmaster.....so i wanted to be the different one. I ordered the muffler out of JEGs and it was only 50 bucks. It sounds awesome. No one else has a tahoe that sounds like mine, but this may also have a little to do with the catallitic convertor not being there but oh well. Hey go out on a limb......i was very happy

any trouble with the performance after the converter were removed....thinking of removing mine on my 2000 limited....not really worried about the check engine light just the performance

Removing the cat is illegal. If you run it on a federal highway.
And will not pass most state and local inspections.
EPA stuff here.

Also removing a cat can and usually makes the performance go down not up.

It may rot run as good with cat removed.

I have a 99 2-dr I have dualed out my exhaust adding some glass packs and removed my cats. The way I understand (and i could be wrong but over 2 year have not seen any change performance wise) is that the rear o2 sensors are just for emission and all they do i trip the service light the front two control the fuel mixture. You can also buy an o2 simulator for summit for around $100 this acually make the computer think the sensors are fine when they are not working. Great sound for little cost

I have had no problems, no lights coming on, nothing. The guy cut about 2 inches behind the sensor and it did not mess anythign up. It runs great, actually i have had no problems. I did however get an even greater and more distinctive sound.

Oh and as far as emission laws, I live in South Carolina and they dont do vehicle inspections here. So thats the other reason i did it.

If you operate it on a federal highway you are subject to emission laws.
