Default Exhaust and Intake completed

Thanks to the guys at American Racing Headers, I was able to complete my exhaust project.

I installed a 1 7/8" long tube header - X-brace combo stainless exhaust. I purchased a stage 3 ported intake TPI, ported my runners and plenum.

In adding the long tube headers, I had to relocate the oil filter. The header was rubbing the side of the filter, so I relocated that filter to the nose of the car.

I finished the exhaust off with a set of Corsa mufflers and Twin Pro Series tips.

Here are a few pictures of the weekend project.

That's a heck of a weekend project....

Looks nice. How's it run & sound? (the link to your video wasn't working at the time I checked)

It sounds very good, I'll have to upload the video to YouTube. That was the video posted on FaceBook.

The car still idles a little high like it did before all the work. 700-750 RPM's. I found a leak in one of the vent lines near the fuel tank, another weekend project for this weekend!

Nice upgrade.

Motor looks good. Painted runners, plenum, and valve covers, or powder coat?

Looks great, did you get the chrome muffler bearing option? 10 more HP by making the exhaust go in a circular motion.

You can run synthetic in the blinkers, but not until they're broke in.
