Default TPiS Coated Headers...What are U running?

Looking for opinion on fitment of these headers.

Better yet, what type of headers are you running?

No problem with fitment. I do suggest you make sure the converter will slip on y-pipe before you install it. Also do not tighten the header bolts until the y-pipe is installed. Very tight fit. Drivers side went in pretty easy and the passanger did after I lowered the starter. Hope this helps.

I'm happy with everything but the coating on mine. After a few years some surface rust showed up around the flange and around the collector.

Default Spark plug changes

How does the TPiS headers affect spark plug changing? The advertise easer changing, is this your experience?

I have the TPIS longtubes on my LT4, I don't know if plugs are easier to change...but it still not too hard. The rear passenger side plug can be a bit of a pain. If I had to do it again I'd get the Exotic Muscle headers, they have a better fir and finish to them IMO.

I also have TPIS long tube headers with the Jet Hot coating. I have been running them for about 5 years now. They were are a great compliment to the rest of the modifications to my engine (see sig.).

The coating seems to be holding up fine.

Fit and installations is ok. I have AFR heads and the no. 7 plug was very close to the no. 7 header tube, too close. This required some dimpling to improve clearance, per TPIS recommendation. I also had to file the flange bolt holes for the no. 1 exhaust port as they did not align properly, it was just a small amount of filing. The y-pipe required some cutting and re-welding to get the center section of the exhaust to be centered under the car.

Just my experience.

Hookers 2149, great fit. I'm using their Y pipe as well. I did not have any problems with this part, although I've heard some others had fitment issues with A4s.

Sometimes fitment depends on the heads that you have too, if you have the L98 plug angle etc.

The only plug that still hard to get to is #2. Other than that, they're all pretty easy to get to with the stock d port heads.

They fit on my Lt1 great! I think they did make spark plugs changes easier also! Again this is on a LT1.
