I installed the Headers and a new high-flow catalytic converter but not the cat-back exhaust. Here's my thread on the header install:

Has anyone on here used Hedman headers?
A friend of mine suggested them also but i have read on a post in here to stay away from Hedman.
I really do want headers and would definitely want the ones that wont rust as soon as i turn it on.
I live in Wisconsin and will be getting collector or hobby plates soon mainly so i don't have to pay to register it each year.
I had to get the regulars because the collector or hobby plates take up to 2 months to receive. They don't do temp plates anymore and I really wanted to drive it so i will get them before next registration.
I don't even think WI tests cars over 20 years old anyway.
That being said i am not against a high flow converter I would prefer to have one but my math says about $200+ for the Y pipe $200+ for the cat and $800+ for a cat back system plus the price of the headers.
Not to mention there are so many different manufactures out there and I don't know what works and what doesn't.
Thank you
Scott

Get out all the extra weight that you can. It will increase performance, cost nothing, and if you sell the parts even make you money.

Thank you. As expected, the headers have discolored but there are no leaks (gaskets, clamps or welds). Other than the one runner that didn't align, it was a straight-forward install. Fixing the blocked catalytic converter fixed the Service Engine Soon issues and my butt-dyno feels a significant boost in performance. Sounds stronger as well.
Here's how the headers looked brand new before starting the engine (8/25/2012):
Here's how they look almost three years later (67/11/2015):
The headers get a little more weathering down below so here's what they looked like brand new:
Here's the same view three years later:
Based on the quality of the headers, I'm interested in their cat-back exhaust. I have the Y-pipe into a single 3-inch cat with another Y-pipe to dual mufflers and quad outlets. I'd rather have the dual pipes and cats with an X-pipe. The writeup says it's 3-inch so it should halve the flow restriction. Even if it's 2-1/2 inch, it's almost a 30% increase in cross section area (7.07 sq. in. for single 3" vs. 9.8 sq. in for dual 2-1/2").

When I got the car he just replaced the injectors .(not sure what brand)
The car runs very well.
The reason I want to do the exhaust is I have a rattle up by the passenger front (im guessing front cat heat shield) Also I would like to give it a little more rumble in the prosess
Once winter comes I will be doing alot more to it as I will have much more time and a fatter wallet.

So does my car. In fact, it ran well even when the injectors were of different spray patterns and volume. One of them had a collapsed filter basket. I knew that because I got the report of the injectors at FIC when I sent them for testing.
I'd get headers and cat back. Not sure what you think but I went with TPIS because I was told that the plugs are easily removed and they are. Quality wise they are good. Not sure why I would want to use true duals unless it does really improve performance overall and not just one point of the curve.

Unfortunately, I have been so swamped I haven't had the time. Maybe I might make the time someday but if things are going well enough for me to take a trip to MN, I might drop by Hitech Motorsport to see what is going on there.
