a 2.5 inch downpipe with 3 inch exhaust...I don't get it

[trh9490]

@Chevyguy2003 the downpipe was setup so that i could make it larger when I make more power but provide the proper flow for now

@trh9490

What mpg are you getting now?

What size injectors?

What are the exact cam specs?(I cannot find any cams designed for a 2.2 cobalt,was thinking maybe you used the 2.0/2.4 comp cam?

What do you think of trifecta performance custom tunes?

vince is amazing.

I actually get t work with him in person since i live withing 30 min of him and was not only the first 2.2 tuned by him, but the first 2.2 tuned EVER. (and first cobalt tuned by him haha). Him and I have had a good time getting it to work perfectly and still get together to tune when needed.

@ncs553

they help it rev faster but loose power in between shifts as the rotating mass doestn keep it all moving..

[ncs553]

do the MRZ pulleys make much of a difference?

[trh9490]

dunno :lol:

havent had to run emissions hahahaha
