If you want the best of the best, why go with the slp exhuast? also if you are hoping to get 500 rwhp on the stock cubes, youd definatly be best off with a tru dueal x pipe setup like the one texas-speed offers. I got the coated pacesetter headers, and can definatly feel a difference. Fit, finish everything was great about them. If you have 1k to spend, maybe get Coated headers, true dual exhuast, and maybe a ud crank pulley. Should put you near the 1k mark, and you might get 30rwhp bolting that stuff up. Good luck, Chris

Previous owner put that on. Does anyone know actual numbers from the SLP single side?

sorry, i don't, but it will NOT flow as much as a set of true duals. 500rwhp N/A is pretty much a max effort build, so true duals would be your best option for exhaust.

also you should prolly ditch the Hypertech III get some extra cash towards your mods...

This was only a temporary tune for me. By later summer I will have my complete build done (hopefully), and will be getting a custom tune.

Ok so I was thinking... What if I keep my SLP single side, and just make a dump right before the Y pipe? Killer sleeper? I love being able to pass for a v6 (single exhaust, debadged). Then putting bus lengths on people who fall for it.

you could do that, i have a electronic cutout in the I pipe b4 it splits off...

QTP make a dual cutout Y pipe that would prolly fit your situation well. their SS headers and that dual cutout y would make a great combo if you wanna spend the money. if you really wanna go all out get two e-cutouts put on it, and then at a push of a button you go from your "v6" quiet to open header drag car. lol

i can tell you with my setup, its a night and day difference between my hooker catback and open cutout (soundwise)... and i love it

Ok plan now is to keep my shitty SLP, and get a really good Y with electric cutout, and awesome headers.

I know everybody says Pacesetter, or QTP, etc is so much cheaper than Kooks, but what are the prices that I could find these at? Also would I need to buy new? Or will used work? Thanks.

Still looking for that Y headers combo...

I got my pacesetters for I think 380 shipped, I didn't get the Y because I had the TSP duals. For the price, and since they are now a sponsor, I see you are in MN you might wanna look the XS Stainless LTs. Under 300 bucks, full stainless, polished, and the reviews are awesome so far. Granted, no frills (3/4", no merge collector, velocity spike, etc.), but bang for buck is high. I would have no problem buying stainless headers used, but used coated, I'd like some serious pics. Mine are a year old with 17k miles. They aren't brand new, but I've taken somewhat care of them and they are in great shape still. Some surface "browning" but nothing drastic.

I've heard a few things about the XS headers that make me just a little suspicious. I think I'll be heading the QTP with Y and electric cutout.

Quick noob question. What's the difference in the Off Road Y, and any other type?

Off road Y = no cats. Catted Y = well, figure it out Note about that though, you wont usually see guys doing single cats because they usually end up being so far down stream that they don't heat up well enough to function in a proper manner. I had a 94 LT1 that was single cat from the factory, when I put LTs on, I had a dual cat Y made up anyhow. I think that is a good choice with the cutout, since it doesn't matter what exhaust you have, the cutout dumps it prior anyhow. What did you hear about the XS? PM me if you want...

I also don't have to worry about emissions whatsoever. So pretty sure I'll be going without Cats anyway.

Here's my suggestion and in order: QTP headers (b/c it has a nice HVMC), finish exhaust all the way back however you want/can afford, UD crank pulley, a cam in the neighborhood of 232/234 (you don't need to do it all at once and a cam makes the LS1 sound great too), gears, and then heads. If you're gonna race it at the track plan for a 12 bolt too.

Basically with 1k, I'd do the exhaust up nice! Do it once and get stainless headers though!!!!

HVMC?

Yes I will be gonig with QTP stainless headers just have to find a good deal. Also with the 500 rwhp number in mind with the mods I'm considering, should I go with 1 3/4" or 1 7/8"?

Will also be getting a UD pulley, looking for a good deal. Also are they any kind of specs on these? I heard good things about SLP, any other brands that are better or cheaper?

Not sure if I want a cam that big. I still want to be daily driveable. Could these be tuned to dd without compramising power?

I'll also be going with a 9" with 3.90's but prob not until next summer.

I bet he would disagree with you. As would I. The design of the header, and merge collecter's can play huge roles in making extra power.
If headers all made the same power pacesetter would be the only place in business as they offer the cheepest header.
LG Motorsports in the vette world would be half the size, and everyone would buy the TSP headers.

Wow. Wish I could see some numbers between Kooks and QTP. Anybody have any?

How do they compare to QTP or Kooks power numbers?

Also should I go with 1 3/4" or 1 7/8" for my goals?

High Velocity Merge Collector.
-probably 1 3/4 if it's stock cubes
-ASP underdrive crank pully is pretty much the standard. Mine works great!
-Yes, tuning counts for alot!

Ok thank you. I am still searching for my 1 3/4" QTP stainless steel headers. Now searching for an ASP underdrive crank pulley. Plus will be waiting for tune until I have heads, cam, intake, and headers here. Should be around the end of August. BTW I am currently working on a Fast 90 deal

Thank you for all the reply's everybody. They have helped a ton.

Everyone likes to add to the motor first. That's silly (fun, but silly). These cars have awesome engines. Reality is, the rest of the car is cheap. Hit the weak points first. Before you do that, decide what you are doing with the car. If it's a street car, do suspension and brakes. This car, and its ability to do what you tell it to, will keep you and your passengers alive -- or not. The better the car stops, turns, and goes, in that order, will add a margin for error when you and/or someone else messes up and the **** hits the fan.

You got your best advice from the guy who said Konis. Get the Koni SAs and Strano's sway bars. There's your grand. Add some brembo blank rotors, Hawk HPS pads, and a complete brake flush. After that, you will have a car that is:
1. tighter
2. better handling
3. better stopping
4. more comfortable
5. safer

The shocks alone will make it a new car that you will enjoy driving more and will inspire more confidence. Everyone likes scary fast but if you don't have the suspension and brakes you back it up, you're asking for it. The C5 brake upgrade and stainless lines would be a good idea too for a few hunskis extra.
