TPIS Headers
Anyone got any issues with them? I'm planning on buying a set tomorrow and would like to know before I buy them in the afternoon. Looking for any "Gotcha"s and "Yowzer" people might have with them. TIA
BTW, I am getting the ceremic coated ones for $750 and without emmissions.
Edit: These will get rid of the Precats, right?

I put TPIS 1 3/4 long tube headers on my 85. The performance gain was well worth it in my opinion. Of course as you can see by my sig. I have a modified engine and they were just part of the total package. Installation is not to bad, but there were some issues I had to deal with. The no. 7 tube needed to be dented slightly to clear the plug, could just be due to my AFR heads. Some of the bolt holes needed some filing so the bolts could be lined up, again could just be due to my AFR heads. The Y pipe needed some cutting and re-welding by a muffler shop to get the exhaust to be centered under the car. The dip stick removal can be a PITA. Good luck I am sure you will enjoy the results, just be patient.

I am just telling you my experience, it was necessary to file both bolt holes on the no. 1 exhaust port. I talked to TPIS and they said sometimes it is necessary with aftermarket heads to make some modifications. As for why, ask TPIS they make the headers!

Issues by the dozen, let me count the ways. I had to spend a whole day of grinding with the air grinder. Lots of weld bead in the header openings, had to ream out the bolt sleeves since they were not perpendicular to the head, had to bend the air tube to clear cover, and ended up tapping one head bolt hole since the sleeve forced bolt in at an angle.
Performance? they are great. Lesson learned? try exotic muscle next time. IMHO.

I have the EM's. Perfect fit, ceramic coating inside and out is top notch.

As added insurance, although not done at TPIS when they install their own headers, I bought a starter blanket and and wrapped my fuel lines in heat wrap

Mine fit great! It was a super easy install, best fitting headers I have ever came across. My coating has got hot though and has some dull places in it. this was do to my cam being retarded though.
However I bought the emission ones because when I installed them I had a basically stock LT1, now with the LT4 heads/intake I am not using the emission tubes. Anyone know what could plug those holes with or should I just have something welded in?
