Recently bought a 2005 Cts-V and am looking for some performance mods i have around 2k to spend and any help would be very appreciated. Im looking for the most noticeable increases in power while keeping its reliability. (used parts preferably)

OBX 1-7/8" headers (http://www.ebay.com/itm/OBX-Exhaust-Header-Manifold-04-07-CTS-V-LS6-5-7L-06-07-LS2-6-0L-V8-Headers-/181049394487?pt=Motors_Car_Truck_Parts_Accessories&hash=item2a27628537&vxp=mtr) ($550), Kooks 6760FC high flow cats (http://www.jegs.com/i/Kooks-Custom-Headers/579/6760-FC/10002/-1) ($450), and a white-box Magnaflow 16636 catback (http://www.ebay.com/itm/Magnaflow-16636-CB-04-Cadillac-CTS-V-5-7L-/400374360663?pt=Motors_Car_Truck_Parts_Accessories&hash=item5d382bea57&vxp=mtr) (which is the '05 part number).

The Magnaflow catback might take some doing--the vendors on eBay will, according to my notes, sell it for $625 (and possibly less), but you have to play their game and make them a low offer. Apparently, they're not allowed to advertise prices that are anywhere near what the thing actually costs.

I would avoid Pacesetter headers, even though they're cheap, because they're a little smaller (1-3/4"). Also, please note that the Magnaflow exhaust is designed to be fitted to your stock manifolds. If you decide to run without catalytic converters, it'll connect to the OBX headers, but if you want to be street legal, you'll have to cut/weld to interpose the Kooks cats. I got everything to fit together roughly using a sawzall, and paid $150 to have a shop finish the job for me.

Also, you'll almost certainly want to budget for a 50 square foot roll of b-quiet Ultimate and 4 sheets of Luxury Liner Pro, plus a roller and adhesive (which will cost you about $400 total). When you're at that point, give a holler. I still haven't made time to write up a build thread on eliminating resonance in the trunk, but suffice it to say that if you don't apply acoustic treatments to the trunk, trunk lid, and lower seatback, the drone at 1800 RPM is eventually going to drive you nuts.

Here's what mine sounds like:

For exhaust, I'd say Magnaflow. Can get for around $600 on ebay shipped to your door and they sound great. I know quite a few people have gone with Pacesetter headers and others have gone with OBX which should be the cheapest option for headers.

Welcome!

Is it stock now? What mileage? If it is stock and higher mileage (80k+), I would take the 2K and invest elsewhere first. I would do a clutch/flywheel upgrade, change out the motor mounts, diff bushing. If you are installing, that should be around 800-1K depending on what you choose. If you like doing burnouts, get some upgraded anti-wheel hop axles from GForce Engineering, and some Rear Cradle bushings from RevShift. That puts you around the $1500-1700 mark. Get a short throw shifter (I have forum member PISNUOFF's shifter assembly...world of difference over stock!). After that, see how you like it. Save up a little more and do H/C/I then. The small things with this car make a HUGE difference. Aftermarket parts are quite a bit more expensive with this vehicle than say the Mustang/Camaro world due to limited market. Keep that in mind.

Enjoy your new ride!

Full exhaust install depending should run around 5 hours labor, depends on your local labor rate. Around here it's roughly $100-140/hr meaning at least $500 for install

Agreed with the above, although I'm a little more specific/anal about what I put in my car. The cheapest and most effective clutch swap that you can do is a F1 Racing Multifriction LS7 clutch kit (comes with a new pilot bearing and PowerTorque CS2529 slave) and you can choose whether to use F1 Racing's excellent 20.4 lb chromoly steel flywheel included in their full kit (http://www.ebay.com/itm/F1-MF-RACE-CLUTCH-KIT-SLAVE-FLYWHEEL-CORVETTE-C6-6-0L-LS2-6-2L-LS3-Z06-7-0L-LS7-/160936745095?pt=Motors_Car_Truck_Parts_Accessories&hash=item257893d887&vxp=mtr) ($660), or get their partial kit (http://www.ebay.com/itm/F1-MF-RACE-CLUTCH-KIT-SLAVE-2005-2011-CORVETTE-C6-6-0L-LS2-6-2L-LS3-Z06-7-0L-LS7-/400359378916?pt=Motors_Car_Truck_Parts_Accessories&hash=item5d37474fe4&vxp=mtr) ($445) and spring for a rebuildable 13 lb Fidanza aluminum flywheel (http://www.ebay.com/itm/FIDANZA-FLYWHEEL-05-10-CORVETTE-6-0L-LS2-6-2L-LS3-C6-Z06-7-0L-LS7-2010-CAMARO-SS-/400368310737?pt=Motors_Car_Truck_Parts_Accessories&hash=item5d37cf99d1&vxp=mtr) ($435).

A lot of people have done well with Azn2dmax's and PISNUOFF's custom short shifters, but I prefer the Katech shifter (http://store.katechengines.com/short-throw-shifter-cts-v-p24.aspx). You'll definitely want to do a complete overhaul of the bushings in the car, which will be a night and day difference in the way the car handles. Also, consider lowering the car and definitely add a Hotchkis or Addco sway bar set. Again, each of the above mods will be a night and day difference--it'll feel like you're driving an entirely new car with each mod.

Over the course of 2 years (and $9,000), my CTS-V underwent some pretty dramatic changes, both cosmetically and functionally. Granted, you don't have the disposable income that older guys do, but I think you'll find yourself following the same path:

If you're only 16, I'd like to think that your dad has plenty of tools. Otherwise, you'll end up spending about $800 on tools. There are instructional how-tos on everything, including your clutch installation.

If your age is right at 19, please do not go blow 10-12k on your car.... 10-12k at your age spent wisely can make your life a lot easier (save a lot of debt/make buying a hosue easier now) which allows you to live a better life the whole way through (IE have more money that you can easily spend on cars/hobbies) Will the V be more fun with the mods, Yes, but really 10-12k more fun... Trust me it can suck to skip the "fun" things now, but when you can have hte disposable income later in life to be able to buy the things you want without thinking about it.. much better.

This is why i am a boring forum member, I can never bring myself to spend the amount of money I would love to spend on my cars. But I don't think i really have any less fun.

I would recommend gettign out and driving your car. Go find some autocross near you. Spend a little extra on tires and entry fees, but it will change your perspective on what you want to do to the car, and may find that it is more enjoyable to learn how to drive good.

P.S. and go buy good tools, those are a lifetime investment. not a few year car investment.

When you decide to get headers, go ahead and get motor mounts while you're there. Will make a world of a difference on the installation. I learned that the hard way

The exhaust isn't bad, its just tedious and a little time consuming. You will want to have the entire thing on jack stands or ramps. Most of those headers will need a lot of room under the car in order to wiggle em in there. I did them on my own in like 6 hours. The rest of the exhaust took like 30minutes.

I have stainless works header back exhaust. It sounds awesome and it went together real easy. I had no fitment issues at all

Best for the pricing... Pacesetters. I don't see how people can downplay them. Kooks makes a 1 3/4, same as Pacesetter... the collector is different, but pricing difference between the two is astronomical. F body guys have no issues with Pacesetters. There's a thread on here with alot of people stating their positive opinions on Pacesetters as well.

I recall reading this on corvetteforums a while back
http://forums.corvetteforum.com/c6-z06-discussion/2965303-1-3-4-headers-vs-1-7-8-headers-my-experience.html

Although it doesn't apply to every single type of headers made, you shouldn't base your opinion with bigger is better. If it always was, we'd be running 7" exhausts. LOL

An option you can have to conserve money would be pacesetters with either cutouts, or muffler delete.

I almost always agree with Fuzzy, but on this one point he differs from what I'd always heard, and that is go with the 1-3/4" primaries on NA Vs, and go with the 1-7/8" on FI Vs. Personally, I have 1-3/4" headers because I didn't know I'd be getting a maggie later on.

Whatever you do, you're going to see 20+ hp and the sound will be amazing. B&B all the way back will sound the most manly, but may not pass the wife test. My setup does pass ... barely ... if that matters.

But people can and probably will continue to go back and forth with "authoritative" posts that show one thing or another for a long time to come. For instance:

From my perspective: if you think you'll be upgrading to a larger displacement motor or a blower at some time in the future, go 1-7/8". Future proof your car. Have a plan and stick to it--don't fall into the trap of buying and rebuying and rebuying better and better versions of the same part, because then you're wasting time and money.

I assume that, along with every other intake/exhaust restriction improvement, the bigger your engine's displacement (or equivalently, the higher the boost you drive into it), the greater the benefit you'll realize.

I don't think I lost any Hp (ok maybe 1.2) with my B&B 1-3/4" headers. So maybe I would be at 514 rwHp instead of 513......that's about 0.2% loss. Think about that for a second.

Ok, so what hardware are you guys using to bolt these headers up, ARP im assuming, with locks or no locks. it has been my experience with headers they leak,if not now they will leak later.

I'm looking at the Pacesetters with the ceramic coating, but also need cats (to pass emissions) and already have magnaflow cat back. what do you recommend gentlemen.

I guess I will need extension O2 leads as well for the fronts, or will I need all four to be extended?

Does PA do the full visual and emissions inspection, or do they just connect OBDII and see if you fail by having cats not warmed, not working, etc? I passed NYC inspection with no cats because I had them tuned out, which made them read READY and passed inspection
