Default which headers on 1994 corvette?

looking to add more power to my car. and i been looking for headers all over the place and i was told that long tube headers might touch the ground if i went over speed bumps. this car is stocked and these are the only headers i can find.
http://www.autopartswarehouse.com/co...cmljZSU3QzE%3D

between those, which is better? the one made out of titanium or the other one? my budget on headers are 1,000 dollars. and i will be installing it. On the left side i see more parts than i do on the right, is their a difference in that? maybe i should get the one with all the small parts or no?

Do a search for EM Headers, no ground clearance issues.

If you do a search you will find most people don't believe shorties will add much power. I guess I haven't driven over many speed bumps but they don't hang that low. If I had to choose between long tubes or speed bumps I would choose long tubes.

You can get EM, Exotic Muscle, headers that will bolt to the stock exhaust, they have (or at least used to have) a collector to cat piece so you could use the stock exhaust. You're better off putting high flow cats, or eliminating the cats if legal, and a cat back exhaust on while you're doing the headers.

EM (Exotic Muscle) Seem to be the most popular on CF
Melrose (Nice)
TPIS
Dougs
Hooker
Hedman
Cooks, not sure if they make one for a vette or not though
JBA

Just to name a few.

Exotic Muscle was having a Group Purchase, you may want to give them a call to see if it is still going on.

"I talked with Merle yesterday and they have just started a new GP for their new design headers. They have a few new cool options. You can add a true merge collector to the headers for $150.00 extra. I've been told its good fo another 5-10+ HP and Tq. This time for the guys who want a 1 5/8" header they can also do this for the GP price. If you do not want any emissions bungs they can omit these for you as well. Merle wanted me to go ahead and post the GP info so here it is. Get your orders in right away he is going on vacation on the 10th of this month.

Exotic Muscle is offering a group purchase on Lt1/L98 Full length headers. Price is normally $771.00 the GP is $671.00 a $100.00 saving for Corvette forum members.

Details: Only 10 sets are offered for Group purchase and after they are gone price goes back up to $771.00. Headers are paid for in advance buy contacting Merle @ Exotic Muscle 480-967-4222. Please leave a message if we do not answer right away. EM accepts Visa, M/C, Amex and money orders. Headers will be shipped in aprox. 6 weeks.

Stats: The headers are ceramic coated inside and out. They come with a 1 3/4" primary tube with 3" slip fit collectors. The headers have o2 sensor bungs and air tube fittings. The flangs are 3/8" thick.

Options: EM offers a slip fit header extension that will adapt to a Corsa cat back or the stock exhaust. They are offered 2 ways, header extensions coated w/out high flow cats ($270) and extions coated w/cats ($549.00). Felpro exhaust gaskets and Stage 8 bolt fasteners are also available".

I was ready to buy these headers
http://www.mamotorworks.com/corvette...eywords=648881
Then I read your note EM I'm thinking since they are doing a group discount now I'm leaning toward them. Do you feel this is the right move and if you do what about the bigger cats would they make a difference or should I save the money. I want headers to just have them, the larger cats I just don't I would really appreciate your thoughts. I talked to Merle yesterday very nice person, I told him I would let him know on Monday, Thank you

What is your goal with the headers? Better performance I would assume. If so, the high flow cats and a cat back exhaust complete the package. Each piece complements the other and the net benefit of all three is greater than the total of the individual pieces.

Yes you are correct, as you said earlier in your other answer. Some times it takes 2 or 3 times to get through my thick head. Thank you

I have Coated TPiS Long Tube 1 3/4" primary / 3" collector headers.

http://www.tpis.com/parts/view/57

Great fit and no ground to header clearance issues.

Stainless Works also has headers but they're pricey!

They both look great and you have experience with the coated, I am going more toward the coated.
Thank you very much for your help.

Youll like the coated worth the money for sure. make sure they are coated in side and out. Really reduces heat temps underhood.

One more note to add:

I had 3" x 3 bolt header collector flanges welded to the TPIS header and exhaust pipe. The header side flange is loose and the exhaust pipe side welded. This allows the headers to be taken off independent of the exhaust system if you pull the engine, replace the starter, pull the tranny or any othe engine / tranny related work requiring removal of the headers. I also use the solid aluminim gaskets which are reusable and don't leak.

I have Hooker Super Comp. headers on my '95 Vette and I still have my stock starter. But I got a heat shield from Mid America for my starter and also wrapped my headers with exhaust wrap. It keeps under the hood temps down and gives a performance boost. 2 50'x2" wraps will do both sides.

Not unless the starter is bad. Stock starter works with most full length headers. A heat shield wouldn't be a bad idea either.

I would also suggest that you make sure the starter wiring, if fact all wiring (.e.g o2 sensor, knock sensor, low oil, etc.) be carefully routed away from the headers. You can also add thermal sleeving to the wires for extra protection.

You can find all sorts of thermal protection for starters and wiring online at Summit Racing.
