Why don't you call us or email us so we can help you? The FAQ section is not a great place to try and troubleshoot an issue.
What size would I need to attach this to a Cobb exhaust?
The 65mm will work for sure, the 80mm should be able to work if the COBB CatBack uses an 80mm flange.
Does the short dp bolt to the first cat on the stock exhaust ?
The Short Downpipe replaces only the stock downpipe which has a single catalytic converter. It will bolt to the stock racepipe which has the second catalytic converter.
I have a 2013 speed3 and I have a ark dts catback exhaust and I was going to buy the catted down pipe and was wondering which flange size would fit. Thanks
The 65mm will work if you currently have the stock racepipe attached to the catback. The 80mm might work if the flange on the catback is an 80mm flange, but I am not familiar with the Ark DTS catback.
I bought the catted DP and hooked it up to the stock exhaust and used the factory donut... if i was to go to a 3 in cat back, do i just remove that donut gasket or do i need to buy an adapter?
If you purchase the 3" cat back it will bolt up fine to the catted downpipe you have. Going from a smaller downpipe/racepipe flange to a larger catback is usually not a problem.
Will this dp bolt to a gt3076 turbo? Says it needs a 3 "dp
We have several customers that run GT3076 turbos with our downpipe, so it would work fine.
Corksport, I have just finished my full Corksport turboback exhaust. Is there any danger to my car being that I do not yet have a Cobb accessport to monitor my engine? I already installed the Corksport fuel pump upgrade and my other mod is the Corksport SRI. I plan on getting the AP as soon as possible. Thanks!
With the pump upgrade you should be safe but to get the most from the parts get the accessport as soon as you can.
