Well I got headers running into 2 1/4's with two dynomax Super Turbos. I
figure I got about 20hp depending or weather conditions They Mostly Help
out in the high end(which is to be expected). Don't Buy the headers from
mopar.. They don't fit.. The Right one touches the steering shaft and
the left one needed the frame to be cut into.. The Kind Mopar sold me
were "JR" headers.. I think that Edelbrock makes a good set though.. The
Dynomax muffs really impress me.. they are quiet and subtle when I am
driving around town and on the highway, but They get VERY loud during
hard throttle. I have one friend who has an s10 with a 350 and
flowmasters, who said that when I was next to him and I reved my motor he
used the word "deafening" to decribe it.. Which, to me, is very cool.

I don't think you could make it in Mass.. They are pretty tough there..
I don't know what my output is without the cat's. I just wanted a
sticker, but I asked the guy if it madethe emissions test and he said
yeah no problem.. This was at a pretty reputable place too.
I am in Rhode Island.
