That's because you're not alone. I scored some older TSP headers locally, they look like they were used for about a week.

MrJonMan

Any tips on where to look besides the parts section on here?

Supercharged111

craigslist and cross your fingers. they pop up here more often than CL though.i've been watching since I got the car in 2012 and finally pulledthe trigger a few months back.

MrJonMan

Yea no luck on CL so far

May I put a twist on this? Curious what everyone would say about doing a cam and FAST intake without doing heads. It all just seems like once you start digging into the engine, you almost SHOULD do everything so that EVERYTHING compliments itself. I suppose no matter what you are leaving something out there.

fast 92 makes an extra 15whp on a bone stock LS6 but it's all 5,000+. no loss of torque below, but the headers, like the cam, will deliver a lot more under the curve.

MrJonMan

I've sent TSP an email, seeing if they will work a deal, because after taxes and shipping, they're only $200 cheaper than LG's.

I did a cam before headers. I actually did heads and cam before headers.
I had a 219/230 cam with an UDP and vararam and it made 370 rhp and 358 rwtq.
I added PRC LS6 2.5 heads and made 384 rwhp 363 rwtq. Don't know what baseline stock numbers were, but it is a 2001.

What were your numbers after headers?

MrJonMan

TSP responded saying the listed price is all they can do.

The price isn't bad until I add the high flow cats, jumps $250!

MrJonMan

Think I might just skip the cats for now and add them later on

quickc5zo6

I added headers along with a FAST intake and ended up with 428 hp 390 tq

I would do headers at the same time and get the tune for both. You'll save money and have less downtime.

Do your homework on the total package based upon your (realistic) goals. Don't just throw parts/money at the set-up piecemeal.

C5Dobie

Depends where you live and what emissions testing is like. I could pass a sniffer test barely running no cats on my bolted G8, but I had an excellent tune. That being said, I would never do that again because the smell can be a dead giveaway to a cop and it just plain stinks especially sitting at a light in the middle of the summer or through a drive-thru etc.

Just save up until you have enough for the full deal, you already got the cam, did you check out melrose headers too?

MrJonMan

Yea the no cats wouldn't be a long term deal, just a temporary to appease the wife of the $ being spent. Plus, I rarely drive the car....about 3k miles a year.

I have not looked into Melrose, or even heard of, but I will now.

You want to make the motor breath the best it can BEFORE you break into the motor. Air intake, Long tube headers (1 3/4), Cat back exhaust, and a dyno tune. Most places will charge you $400 ish for a full dyno tune. Once you install more mods the tuner normally will charge a much smaller fee per hour for a tune.

Once thats done, then you can save more $$ for parts for the motor. Cam, heads, Fast intake, TB... etc...

Cliff notes: cam, rods, springs ordered. Buying headers too, just trying to get a better deal.

The cam is already ordered, custom grind through 510 Engineering, also push rods & springs. Going to probably do LS7 lifters as well.

I've decided to do headers too, just trying to get Texas Speed to wiggle on their price a bit, worse case I will just go no cats for now & save $250.

I've already got a vararam on the car, and a cat back system. The exhaust is stainless & sounds good, but was put on by a previous owner and has NO naming on it anywhere. More than likely it's a Vinci set up, that's what a plate in the engine bay says did work to it, but when I contacted them (3yrs ago) they couldn't give much info.

Appreciate everyone's input

MrJonMan

Oh and here's my cam specs

228/232 .629”/.629” 112 LSA +3 advance (with 1.7 ratio rockers)

Maxx_Z06

Nice 510 Race Engineering will definitely get you setup with a nice custom grind. They did the build on my car for me last August. Great bunch of guys. Are you doing the labor yourself?

If you're going to be out there for the dyno day on the 3rd of next month maybe we'll cross paths.

MrJonMan

I'm going to try & make the dyno day but have a wedding the same day.

Very good friend of mine is a head mechanic at a dealer....so "we're" doing the install.
