TPIS or EM headers for the 1994 C4 dedicated track car? currently has short light cat back exhaust with stock manifold. Thanks

TPIS has been good to me since I can change plugs easily

For a dedicated track car, having equal length primaries might make a difference. I know TPIS aren't. I was going to purchase a set years ago and spoke with Myron Cottrell (owner) who confirmed they weren't. I'm running ARH which is a quality header (among others including TPIS) and have primaries that are equal or close to equal lenth.

What is ARH? american racing? They have stainless is it worth the extra money for stainless?

bangorgreg

just the ARH headers are $1100

My car gained a tenth and a half compared with Hookers with no other changes.

Ease of assembly? Difficult to change plugs? How much do you think I can get over the TPIS? ground clearance? Any drawbacks?

TPIS here. Plug change is a snap. Fit is great on my 87. I have a TPIS intake and it is also well designed. One problem with TPIS is, they will lie to you. Our cars are so old I dont think they keep a lot of stuff in stock. I ordered my headers and they said they would ship out in 2 days. I think I got them 2 1/2 weeks later.

just ordered Melrose headers after speaking to Carolina Auto Masters who say that Melrose have always fit perfect and are made here in the US. Fingers crossed-stay tuned for results

I have the TPIS header, look good, fit great and easy to work around. They may not be exact in length if top speed isn't your MO they should work fine.

I just reinstalled my ARH headers last night after having my heads freshened up. Took less than 15 minutes including tightening bolts. Good ground clearance and I can change plugs in 10 minutes. The only caveat is if you have the factory oil cooler, you will need to install a remote filter. If you are not running the heat exchanger, you're good to go. Here are a couple of pictures showing the plug access.

Do your headers (both manufactures) connect easily to the Y-pipe before the Cat at the end. I don't have pre-cats just a big Cat. at the end of the y-pipe.

Small price to pay if you want equal length headers. If I had known, I'd have done it myself since now I have to fix my oil cooler. I checked and rechecked and found it to be leaking. Not where it mates with the block but below that. Change of gasket and torque to 25 ft/lbs doesn't cure it and the dye show it to be coming from below the mating point.

aklim

TPIS does for sure.

Stay away from anything by EM. Merle is a real POS. They don't stand behind what they sell in spite of what their website claims.

Say what!

Happy EM customer here

I run Melrose Headers on my 91 and Stainless Works on my 96. Both fit nice. I have heard over the years that the TPIS headers fit nice.

As far as Exotic Muscle, I just purchase an item off of them and everything was as described and explained. They seem to have more C4 parts than any other vendor, especially body parts. I would recommend them and will purchase from them again.

TPIS, here. The fit was okay and the only gripe I had was clearance issues with one plug wire. Their solution was to dimple that exhaust tube.

Haven't dinged anything yet.
