Speed Daddy's site states 1.5" Primary - 2.5" Outlet , while the Speed Daddy Ebay store states Inlet/ Outlet: 1.50"/ 3.00".
Is that just a typo, or do they make a 3" outlet for a 3" cat-back system? I don't see a 2.5" outlet for sale on ebay, and I only see a 2.5" outlet listed on their own website.

Hi, Moved your post as it wouldn't get many visits on the end of a How to thread. Hope this helps you get a better response.

The outlet flange, where it bolts to the cat-back is 2.5". The downpipe itself is, however, 3".

Thanks, makes perfect sense.Originally Posted by DanGTP
Thank you sir! I noticed it was gone right after I posted it, had no idea where it went. What confused me was someone had replied to the post. I wound up buying the speed daddy headers and spun Magnaflow high flow cat. Which now that I think of it, brings me to one other question I had...
The SD kit comes with 2 3" clamps and 2 2.25" clamps. From what I can tell the whole header kit is 3"(from what I guestimate), then it steps down to 2.25" at what looks looks to be where it would connect to a resonator, though I have to admit I haven't been under the car yet to really look.
So using this logic I assumed the 2 2.25" clamps would be for if you were going to install a 2.25" catalytic converter. I bought 4 3" slip-fit band clamps. Two fo rthe crossover, and two for the spun 3" Magnaflow high-flow catalytic converter.
Did I do it right?

Negative! You need 2ea 3in clamps and 2ea 2.25 clamps
03-09-2013
Nope, but close.
The front headers go to a collector pipe (crossover) then over the trans to the rear header collector. That whole pipe is 2.25, so will need 2 of those 2.25 clamps.
The two 3in clamps go where the downpipe goes to the cat-back. If you choose to not run a cat you will use them there.
You can kind of see the frist band clamp up front and I have one horse shoe clamp on there, but was replaced with a band clamp very soon after.

Got it, thanks for the info!

I need some advice from the guru's!
I'm in the dis-assembly phase and I've come up against a resonator that is split down the seem, and has completely rotten/stripped bolts where it connects to the down pipe. The cat back is one piece all the back to the mufflers, including resonator.
What do you guys use to replace the resonator? I see where the rear Y pipe connects to it there is a weird angle and looks like it would be hell to get any type of clamp on there for an aftermarket resonator.
Do you guys see anything I could pick up over at autozone to make this work? or maybe Andy's Auto Sport Body Kits - Your Body Kit Superstore! (local I could pick it up tomorrow)?

I'm looking at this one, if they can get it in stock by tomorrow:
Walker Exhaust/Installer glass pack resonator pipe (24454) | Resonator | AutoZone.com
Then just weld the approprite flange on the cat-end. The only thing I'm worried about is how the pipe coming out the back of the resonator enters the resonator at a wierd angle.

The resonator is before the y split and after the down pipe.So it is a straight through design,placed in the middle of the car.I have a Walker res myself,it;s held up so far and made this pig quietier.

I found this in stock locally, it's an exact replacement at 31". It's actually red.
Buy Dynomax Thrush Glass Pack Mufflers 24205 at Advance Auto Parts
I'm just going to butt joint band clamp the back. The vehicle has 200k, I know that Y pipe isn't going to last forever. I'm looking for a slip on/in two bolt adapter for the front.
**edited out because it was a stupid question : )

I just straight piped mine from the headers to the stock mufflers for now. I don't experience the rasp effect people speak of. But it works for me.

Its raspy with WOT you just can't hear it inside the car

After looking at a stock resonator and a glass pack of approximately the right size. I get the glass pack each time. They look identical internally. Glass pack might give less service life..but heck..

We got the 31" Thrush glasspack. Now I just need an adapter. This one is 2.25" OD I could slip into/weld into the new glasspack. Would stepping it down like that slightly to connect the resonator have any adverse effects? Nothing to worry about with a naturally aspirated engine?
