i been thinking bout upgraded to a 4" any suggestions? or particular brands to go with?

Just put one on from tvdiesel. 4" diamond eye it sound good in prove fuel milage and power

i'm also considering some gauges..probably just a pyro and boost.. any suggestions on what brand to go with? i'd prefer them to be black to match the my dash..

well i went with Glow Shift has good deal going on for 3 pod and gauges. just take look in my garage took few pics of them the pod does come black mine been painted to match the faces on gauges are black also

how do you like the chip by SS??

i love it huge difference in power. i was gonna get the 80 horse, but didnt have a 4"exhaust or gauges

I have the Diamond Eye 4" as well. No muffler. I like it. I also have VDO gauges, they are a little cheaper than Autometer and are black face with white letters/numbers. I got them at summit.

I recently installed 4" stainless diamond eye/warpspeed with muffler. Very happy. Good increase in bottom end and not too much noise. Little tough to get everything lined up so it wouldn't touch the floor.
