I just purchased an invidia dp and an hks up. I plan to run a 3" straight pipe with it but don't have the money for that right now. My question is, will i be able to bolt up the dp to my stock catback or will i have to mod or buy a new flange? I am open to all suggestions.

 

also can i use the stock gaskets from the uppipe or should i buy a new set?

 

It should bolt up fine.

Defenitely get new gaskets for the uppipe, it's not an install you want to do twice.

 

i just used my old gasket for the downpipe...works fine...but yea it would be better to get a new gasket...

 

YOU should get new gasket and the downpipe will bolt up nicely... You might consider just keeping the stock CBE on cuz it will keep the noise down and it keeps a nice low profile but still have noticeable gains
