Looking for the HP more than sound. What Cam would be recommended? .. With a cam install what else is a must do? Swap/add/remove?

2001 Camaro SS

Installing currently Hooker 16811HKR Cat Back
Next Installing edelbrock #65732 Short Tube Headers

Cam is next step and this will all get banged out within the next month.

PREDATOR-Z

Remove the short tube header and install longtubes

JonasSS

Need the Cats .. otherwise I would ... this needs to still be street legal and be able to pass emissions

PREDATOR-Z

Cali ??

JonasSS

No, NY, NJ, and PA. I'm aggressive .. but new to work that is more than rotors, brakes, oil changed, flushes .. etc .... thought the cat would be a must in order to pass inspections

PREDATOR-Z

Some states require cats in original location, therefore shorties are it, but if not then Longtubes and 400 cfm aftermarket cats on a nice 2.5>2.75 Y is usualy the norm.
See shorties will net you maybe 5rwhp (being a 2001), that is weak for the cost IMO.

Did you allready buy the shorties?

JonasSS

1. No I did not buy them yet. That was my other item I was thinking about. Would I be able to put long tubes in, then throw in some high flow cats .. hopefully all bolt in of course .. new Y pipe then a hooker exhaust..

2. Why only 5rwhp for an 01 ... is there something different stock-wise about an 01 that I would only get 5?

TSP228R 228/228 .588 .588 112lsa, Longtubes, UD Pulley, P&P Stock TB, PAC Dual .650' Springs, Comp Chromoly 7.400 Push Rods, Dyno Tune.... Im making about 407whp & 388wtq on a Dynojet with this combo and am still running stock 241 heads and LS6 intake.... This is a great cam....

Because 01/02 stock manifolds flow better than all previous manifolds (not including vettes).
Yes LTs with catted Y would be street legal, you can check with your State's laws regarding that. If you are on a budget, Pacesetters 1 3/4, buy a flowmaster colector Y and 2 aftermarket cats and make your own custom Y (have it made mandrel bent).
For about ~700$ you can then have a good exhaust.

are you M6 or A4?

Some state's inspections are really pickey about the cats being "in the stock location" which technically with LT's and aftermarket cats they wouldnt be. Luckily I have a good inspecation shop that doesnt look that hard. We dont have emissions in my county thank God, but its in a few surrounding ones. With the camshaft in my car, I'd probably be fucked, lol.

The best advice I can give you would be to listen to these guys especially predator z they seem to know what they are talking about..

JonasSS

I drool over the long tube Pace Setters at 1 3/4 .. but I'm gonna have to go legal on this .. looks like the have 72C1349 mid sized headers 50 states legal ... I am jsut trying to figure out ... how ...

What is the pipe set up with mid sized headers? .. again new .. ( but I'm a plumber .. so piping comes a bit natural )

Will mid sized headers still require me to move my cats and get a new Y pipe?

honestly i would only get long tube headers. I know that you are wanting to stay legal but i know of alot of cars on here that live in areas(except cali) that test and they have long tube headers and a catted y and still pass

JonasSS

Again. I would love to go with long tubes ... I dont know enough about the middle fabrication from the end of the long tubes to the beginning of the cat back exhaust .. or .. would you still use a conventional hooker cat back?

Bulldog0082

Completely agree i got the same setup and its the ****.

I believe the Bassani Optimum Length Header system would put the catalytic converters fairly close to the stock position; but please correct me if I'm wrong!

I'd say definitely look at changing to a LS2 timing chain, get new valve springs and pushrods. I wouldn't waste the money with shorty headers...definitely long tubes all the way. I did ARH long tubes and a catted y-pipe....awesome fitment and clearance but they will set you back some coin. The long tubes will net you the most hp since that's what you're wanting but the sound is gonna come along with it too.

I rocked an ORY and LT headers with my hotcam in VA for years. No one ever said anything.

The catback part of the car will stay the same. Check out the Y pipe in my Sig. Its a pacesetter Y pipe but only with a 4" flowmaster merge. If I end up keeping this exhaust then I will probably add some cats to it.

Without a cam, my hooker catback and ORY was as quiet as my stock exhaust at idle. Before this exhaust I had a TSP catted Y and a BorlaMouth. The catted Y had terrible ground clearance! You would be better off having one made, or just welding one yourself (seriously about 15 minutes of playing with a mig welder will make you confident in your ability to make an exhaust for your car).

Anyway, with a cam you'll end up wishing you went with longtubes. You'd be missing out on a lot of fun in the 4k+ range!

How are you going to handle the tuning part of the cam/exhaust/SES lights?

Yes you can use a conventional catback to whatever y-pipe you use. MAC mid length headers are better than stock manifolds as are shorty headers, dont listen to anyone who tells you different.

If these are LT headers, you are wrong. Cats on our cars are right after the manifolds, so even if you had the cats right off the collector on teh LT's it would 'technically' not be in the stock location.
