how does this idea sound for exhaust mods

[kking89]

I want to get a 3 inch bolt it DP with Cat from ZZP. Then I plan on getting Magnaflow mufflers. And ideas anyone? Does the DP sound like a good idea. Idk if I should get a Shorty

 

[Bio248]

a shorty you'd have to do some welding.

skip the cat if you can get someone to tune out the code.

the exhaust sounds like **** whatever you do, keep the stock mufflers.

 

[kking89]

Won't I not pass emissions if I get not cat

 

[Matt Palm]

if they tune the code out you will pass

who would i go to for that? my brother works at a GM dealership wonder if they could.


also wouldn't a 3inch DP with no cat fail emissions?

 

[Matt Palm]

why not just get a 3 inch dp with a cat?

Thats what i said i want. 3inch DP with Cat from ZZP.



But BIO i said i would need the code thrown from the cat tuned out

just get one dont go for the stainless no benefits. and get the pre paid label in option 2. you send back your stock dp and they will give you a $50 coupon

im still a little confused. will that down pipe throw any codes? also can i send it to them after i install the new down pipe?

 

[Matt Palm]

it wont throw codes if it has a cat. and yes once you install your old one out ship it back

so no light will come on what so ever?

 

[Matt Palm]

nope

Or you could do what they have convinced me to do. I was looking at the same downpipe with cat but I found speed daddy headers with a downpipe for only 220 shipped to door.

 

[Matt Palm]

offer them 200 they will take it. but then also get a high flow cat for like 70ish dollars along with a o2 extension and double walled flex pipe if you go that route

Alright I'll try offering 200. And I have to get a catalytic converter with it?

 

[Matt Palm]

or you can cut your current one out and weld that in

Ok so I can go on ebay and get a universal cat as long as its 3" diameter, correct?

 

[kking89]

i heard with speed daddy you need to do some modifications to the headers to make them fit

 

[Matt Palm]

that goes for almost every set of headers

Sometimes. They're hit or miss is what I've heard. I know a guy that's installing mine for $200. Not bad at all if you ask me I just want it done correctly. I'm doing the rest my self
