I already have PMed Donna about this but I know she's busy so maybe someone could help me out.

I have the GMPP Performance Cat-back. I'm looking to complete my performance for being N/A (without internals). I know the Header will work that they (they being CA.com) got.

My question is as follows: Since I have the GMPP Performance CB should I get the 2.5" or the 3" DP/Hi-flow cat?

Also does the Header bolt up to the DP?

Thanks for you help.

 

These are a factory replacement so no welding or cutting is necessary. Will bolt right up to factory header, and most aftermarket shorty headers.

Taken right from their site. I need to read better/closer. NVM thsi topic! <--- don't because I still need to figure out if I need the 2.5" or 3" DP!!!!!

 

Being N/A you dont want 3", especially on a 4 banger. 2.5" is more than fine.

 

alright thanks.

I now know what a good chunk of my tax return will be!

 

Definatly go 2.5", the 3" was even too big for my 2.4.

 

what he said^^^^^^

 

Gracias fellow balt owners.

Now I just need to wait until next year to get them. I will be getting a TWM Short throw for a christmas present. From: Me. To: Me!!!
