[mutiger93gt]

I bought my CP-E downpipe used and need to know what size bolts/nuts I need to attach the downpipe to the catback exhaust. the catback is stock.

thanks for the help

Use the stock bolts from the cat back

And get a hpfp before you go boom boom

We put that in first. We had trouble with the down O2 so I have to wait for that to get here before we finish her up.

For the CP-E downpipe, to bolt the downpipe to the exhaust, do you use the bolts that bolted the downpipe to the second cat pipe?

No you use the bolts that connect the 2nd cat to the cat-back

On my car, these appear to be studs. CP-E is telling me to use a 1/2 bolt, with 2 lock washers and the length of the bolts to be 3.25". I was going to just use the bolts that connect the first and second cats, is this wrong or right?

They are just bolts, use whatever fits in there with room for a nut on the other side.

@mutiger9gt are you getting a cel 2096 yet after the DP install? how many bungs do you have after the catalack on the DP? I'm wondering if the previous owner I got mine from installed a second bung to solve the check engine light problem.

I just have two and as soon as I get her up and running I will let you know.

The bolts I ended up using per CP-E customer service were a 3.5"x1/2" bolts. I used two flat washers, one lock washer and a nut.

Thanks guys for the help.
