Thread: Complete Exhaust Replacement for Christmas - Questions

Hi folks.

I am no expert when it comes to the tech of the 3800 so I need to turn to you for the help. My wife is letting me get a complete exhaust system put on my 04 Comp-G for Christmas. I have a few holes in the exhaust and I can see one of my mufflers hanging a bit lower that the other. So its time to get it all replaced.

I am interested in replacing the manifolds all the way to the tail pipes for supporting mods when I decide to upgrade the pulley and stuff later on. So what are my options here? I see on ZZPs website they have plogs, headers, downpipes, catted, non catted, etc etc.

Would a catless DP really help any? What kind of codes or pcm issues can I expect when doing this? Also price is somewhat of a factor I dont need the 600 dollar headers that may give me a few extra HP over the 150 dollar plogs. So im looking for the most bang for the buck that will a great supporting mod for down the road mods.

I appriciate everyones time and opinions.

Speed Daddy headers from EBay.

Catless.

$200.

Glasspack for a resonator $30~ (Long one, like 26"+)

Tips of your choice, mufflers like SLP, Borla, Magnaflow, Dynomax Super Turbo's (Are VERY quiet)

Also, link in my signature...read it.

What's the reason for replacing the resonator?

I dont like the farting sound that the v6 will make if its just straight exhaust. I have seen alot of youtube videos with res' removed and all you hear is popping and rasp. I understand that a v6 has this by nature but to be able to minimize this would be nice.

Does removing the res really help with performance? I like the glasspack idea.

If I go catless then what would I do with the O2 sensor that is behind the cat?

^^^ delete it by a tune or run a sim
just make sure you get an o2 extension harness for when the headers go in
