My 2006 Corvette C6, is 100% stock, with only 4k miles... With the winter months here in the northeast, I have begun to think about some basic modifications. Here is what I am looking to achieve:

I would like to bring just a little more life / responsiveness out of my LS2 motor...all while keeping the car running reliable. Since I live in an enclosed community, I don't want the car to sound obnoxiously loud. I use my C6 soley for street driving.

This is what I am thinking:

-Mild / Street Headers (LG, Kooks ???)
-BB Route 66 or GHL Exhaust
-Cold Air Intake (Callaway)
-Professional Tune

I am trying to learn more about which header (if any) would be appropriate. In another recent thread, I see that LG is coming out with their one-piece Street Header for the C6 (header and x-pipe). Alot of people seem excited about this new offering.

Questions from a Novice:

1. What is the big benefit of a one-piece set-up (header & x-pipe)?

2. Regular header Question- trying to understand the difference / benefits of a regular header in terms of the 1 3/4 vs. 1 7/8 sizing. Is the 1 3/4 considered a more mild / street header?

3. The LG Street Header Combo has a 2 1/2 out...which makes it an easy bolt on to say the stock C6 exhaust. Does any other brand of (decent) headers / X-Pipe Combo have a similar 2 1/2 out?

4. Is there any other brand manufacturers who produce headers which is considered "mild" / "street"? Something which is not too agressive?

5. Tune - To plan to keep this car for a long time (years)...is there anything I should know upon considering a Tune, which will keep it running reliable? I certainly do not want a tune to create any long-term problems for my engine

Thanks for your help and guidance!

 

imo, in that case leave the exhaust alone, unfortunately that includes headers. you can switch the cats if you want but it's alot of work for the results.
good choices
imo, a bit raspy, but it's your exhaust, not mine. it's up to you. some work better than others, however, there are always tradeoffs. the exhaust system also contains the combustion sound wave.
consider all parts as a system, try to configure them so one compliments the other. meaning, air in air out. the engine it still an 'air pump'.
get references, don't just trust anyone.
basically, cam mods. will dictate the 1 7/8.
imo, buyer beware.

 

Leave the stock catback alone if you want to keep the car quiet.
Headers, intake and tune. Might need a 160* T-stat too.

Another option is to leave your exhaust completely stock and do an intake and a cam desighed to work with stock manifolds.

Alternatively, if you are an M6, put some 4.10s in. An A6 will respond to 3.15s and/or a 3000 stall torque converter. Nice thing about starting here is that you have no emissions concerns since you aren't messing with the motor. Then you can decide later how much you really want to do to the motor.

 

You'll be fine with headers only as long as you leave the stock catback alone and keep some high flow cats. This gets you the best exhaust gains without all the noise.

CAI is a must.

T-stat, in my opinion, is a must.

Consider a Ported Intake and Throttlebody. You'll get more power - 10 rwhp and torque AND much improved throttle response- and stay with stock reliability.

Get a good tune from the professional tuner nearest you.

You'll be very happy with your basic bolt-on car's performance

 

I see your from NJ. It might be a good idea to contact ECS or CARTEK.
They have the experience to MOD your car properly unless your a do
it yourself guy. A pro tuner is a must. There are many around and it
would be a good idea to research it out. Good Luck

 

Give us a call…I will be more than happy to go over any questions you may have.

Dangerous thing to do.
Come spring your wallet may be considerably thinner!

 

Get some miles on it so that you know it is running good before doing alot of mods. Worse thing to happen is something not running right and it can be tied to mods when mods not the real problem. Haste can make waste. If you can afford to pay for an warranty item out of your own pocket, then do it; otherwise, don't do it. Get the bugs out of the car first.

 

stay stock stay happy

 

Leave it stock. There is more than enough power for your type of driving and you will have no warranty problems.

 

Just bolt on's like headers, CAI and a professional tune will make the world of difference. If after this has been done and you want a little more sound, listen to other guys cars with different cat backs on them. Hearing them in person is better than sound clips. Good luck.

 

Put a turbo on it. You won't have to deal with which CAI to buy or headers and they tend to quit down the exhaust as well.
