Default Headers Installed

Ya Baby. What a difference. A Must do mod for the LT-5.
My Set up is Watson 1 7/8" Small tubes Ceramic Coated, Random Tech cats (with shields) Straights back to Borlas . I was lucky and got a deal on the headers the cats/pipes were top notch done as it bolts right to ware the resonator should be Hangers and all. Much Louder. Resonance has been introduced into the system. I Like It.
Took her for a neighborhood drive under 1500-2000 rpms there is a definite increase in torque/power.
I dont know if these will pass smog so I just cut the pipes and used Butt Stainless connectors (nice) in my exhaust so I can replace my stock manifolds if needed. Need to really get a camera to show.
Install was really not bad at all Put in fresh O2 sensors, Made my own extension weather pack deal, (nappa) Dip stick lined up perfect, no new grommet needed. I wrapped all Wires and hoses (clutch line) with Thermo tech wrap, (very similar to the wrap used for the motor mounts).
Next stop Mild porting. Here is a pic of the headers before cleaning/purchase.

Hmmmmm...., Those Heat Shields make great sense.

Wonder if anybody knows where a set could be found. The cats on the end of my SW tend to warm up my floorboards.

The car is a 92. I bought the headers from a forum member, (they wouldn't pass visual Calif inspection).
When installing these i found in my exhaust system when they eliminated the Resonator, they cut off the resonator 2"pipes and welded right over them leaving a choke point. Well I cut this out.
Removing that choke point, installing new 02 sensors and the headers made a definite power increase really woke up the car, I wound it up to about 4K plus and started a sideways traction thing. Not wide open. Never did that before. Also noticed a slight miss now at idle.
