yeah i know all about that .... i always go back and forth about buying the gmpp exhaust. the stock ss/sc exhaust isnt the most restrictive exhaust in the world. i just dont want to back myself into a corner with a 2.25" exhaust incase i ever decide to add more power you know.

 

Yea... thats the only problem.

What is your other choice?

 

well im not really looking into a catback right now .... i would prob. only buy a 2.50" in the future, but i dont want to pay $700 for the corsa touring. i dont want a loud exhaust man.

 

So if I was going to go with a vibrant header/dp what would be a good catback? I only got GM stage 2 right now for mods. I would like to get the hahn header/dp but its too pricey. Also would I notice any gains at all if I went with a 2.9 pulley and dual pass? Im on the stage 2 tune.
