Glass pack or resonator

Just gonna leave my two cats on, but can't decide if I should use two resonators or if I should do two glass packs made by magnaflow. What's the difference?

Resonators...they draw in the rasp more then a glass pack. BTW if you go glass pack buy thrush units for a lot cheaper then magna flows version at advance.

Advance auto sells them and there is no difference in the glass packs just brand name.

Nothing you can do....a glass pack is pretty much a straight pipe with a bit of matt material. Honestly you'd be cheaper just to straight pipe the car all together. As for how they last...well that's up to the weather and winter salt.

Will straight pipe hurt the cats and then hurt the engine?

If I may ask, how will it not hurt the Cats or engine? I thought allowing air back up into the cats and engine can but them up?

Back pressure is a myth on non turbo vehicles...and mufflers have nothing to do with the condition of your cats. Removing them would increase exhaust velocity allowing the exhaust to leave the vehicle at a higher rate. My question to you is how would air be put back up into the engine going off of your question.

Because when you turn the engine off, the cold air can be sucked back up into the engine causing the valves to crack, example would be like placing a hot glass into a bucket of cold water

Also when you down shift, air get sucked back up there which causes the raspy popping sound u hear on straight pipe from what I was told

Please find me an example of this happening...I've run straight pipes on two vehicles with years of good service, and plenty others do too. If this is a concern then we should post more on it.

The raspy pop happens even without downshifting BTW. You'll need a good mid pipe to combat that. Except you wish to run a non true dual exhaust so you can't use one. So whatever sound it produces you'll be stuck without the ability to affect tone with just a mid pipe swap.

I would love to see more posts on it, thank you for your help. I'm not trying to say your wrong, I'm just being a customer to you and I am an open book and wanna learn

---------- Post added at 05:37 PM ---------- Previous post was at 05:35 PM ----------

I completely understand. So if I ran magnaflow glass pack with the way my pipes are, what kind of sound should I expect? Or even better yet what if I ran straight pipe, what sound should I expect?

Not much more then you have now....just the way a non true dual setup is. If you're going to spend the money on it as I have been saying in all the different threads you need to true dual it. You think that it will be so loud you'll get in trouble or be obnoxious however our v6s are quiet compared to most other exhaust since you have cats. That's as much help as I can be right now. I have had 9 custom exhaust made for a v6 and have tried many combos. Just post your vids when you're done deciding what you want so we can add it to our sound clip sticky. If there's anything more to your questions I'll try my best to help.

I completely understand and thank you lots, I just fear if I get magna flow glass packs it will sound like a stock muffler and if I do straight pipe it'll sound like a ricer

Remember though I run a true dual setup...I can't tell you how straight will sound on a non true dual car.

Well that would mean going to a true dual exhaust...so you'd get louder, deeper, and with a midpipe the ability to change tone.
