Default New to Corvettes

Alright, I am new to this forum and I just got my first Corvette, a C6 about 6 months ago. She's a 2007, black, LT1, 6 speed with 7,500 miles. I am wondering from all the experts out there, if you were me, what are the top 3 modifications you would perform first. If exhaust is something to recommend, I don't want anything that would be noisier than the OEM's.

Thanks in advance for the feedback!

I would say CAI and tune definitely. Headers too but will increase the exhause note even with stock cat back. I have an 08 ls3 and just with a CAI and tune I picked up 25 RWHP peak and up to 35-40 HP at certain points in the power band. Just need a good tuner, u definitely wont get that much with a diablo ot these preprogrammed devices. Good luck

Headers vararam and tune. I ran headers with stock exhuast for a while and it really wasnt any louder. The other mods added about 30 rwhp and made the car noticeably more powerful. It shaved several tenths off my quater time.

According to this you can't add headers or exhaust.

The change in noise with headers was almost un-noticeable with the stock exhuast still hooked up.

Welcome to the board!

Top 3 depends upon how you drive and if you are budget constrained. What would you like to improve? Off the line? Highway speed? cornering?

A common choice is headers, cold air intake, and tune. Nice gains accross the power band and no negative effect on MPG or drivability. If you do a lot of stoplight racing, 4.10 gears, better tires and a MGW shifter could vastly improve 0 -60 MPH time.

As far as noise goes, headers (with highflow cats) on the stock exhaust are not loud. If you're in my neck of the woods come by and we'll take a ride and you can decide on the noise level for yourself.

First, do you want to still pass MD inspection? And second, how much are you worried about keeping your factory warranty?

Based on that, some of the answers above don't meet your criteria, or might. But the noise above OEM will most likely be affected by anything done to the exhaust, and that includes mufflers, cat back exhaust, X pipe or headers. So, if that's your criteria, those items are out.

The only other one that very likely won't affect noise or your warranty (as long as it's connected properly) is an intake as long as it doesn't cause a hydrolock (ingestion of water). Rear gears, tune, will void parts of the warranty as may/will headers.

Its not I assure you. Ive had several different header exhuast setups and the headers with the stock exhuast produces very little noise over stock. I was quite dissapointed because I though it was going to be louder than it ended up being.

Wow, thanks to everyone so far that has replied. I like the idea of cold air intake and exhaust as I could probably do those myself with the help of a good friend with a lift in his garage.

What's the best CAI for the buck and what are a couple recommendations on a full exhaust system that isn't much louder that the stock one?

Thanks.

vararam is probably the best CAI, although quality control hasn't always been their strong suit. Good news it has gotten better and customer service is very good. There are a couple others that are good too. Plenty of arguements on the topic in lots of threads that you can research here.

There is no point in replacing the cat back except to increase loudness or give the car a rumble. There's no real gain on a nearly stock C6 from messing with the exhaust. If you do the exhaust, its headers with cats and keep the stock mufflers so that you meet your goal of a relatively quiet car.

The only way you can even come close to finding actual HP gains (or losses) between mods is to use the exact same dyno with same weather conditions. Naturally, going from one dyno to another can give much different numbers even without mods.
