sup everyone i'm getting the 6/16 plenum kit stillen headers and gen2 catback system and wondering what will be my HP gain and TQ gain..... i try to go with alphawerks but they discontinue them.....

 

don't expect anything mind-blowing.

high expectations with these mods will only disappoint you.

'nuff said.

 

i meant 5/16 plenum kit

 

For the spacer, you will get the gains shown in the dyno section of our website.

But I can make a suggestion... You said you were going to get headers. I recommend getting test pipes instead of the headers.

They will cost far less. The installation is a lot easier. And they will make better gains when connected to your aftermarket exhaust.
