Theirs enough clearence to run two 2.5" pipes over the axle I know that much.

 

Kooks did it, and that (2) 3" pipes side by side. You just need a PHB relocation kit.

 

There is enough to run dual 3 inch with no relocating, see the post I made earlier

Used dual setups go for 100 to 1500 depending on material and parts. My dual setup under the axle with parts and labor ran me a little over 600 and was ridiculously quiet. So add the cost of cutouts to that

 

...I don't have anymore questions. At least regarding this thread. However, if you want to answer some other unrelated questions, I have plenty of other threads.

I haven't really gotten a straightforward answer on those threads. And yes, the last one IS serious, or atleast I'd like serious answers, but because it's virtually pointless (and useless), it's more like a roflcoaster.

 

^^^^ whats wrong with you^^^^

Your threads make little to no sense..That's why your not getting "straight" answers

 

New ? Where are you buying stock systems with cats for $75

 

4 cats equals 2 high flow cats. Sorry but that logic is *** backwards.

 

Used, and Locally. I live in Goodwell, Oklahoma. Small town, really small.

Fine. 4 stock cats = double the flow of 2 stock cats, which only seem to be a 5-7rwhp restriction on an all stock f-body. Which makes around 300rwhp. So I figure a 10-13rwhp drop at 600rwhp, or maybe a 4rwhp drop at 500rwhp. So a minor restriction at 500rwhp. I think you're thinking of running them one after the other, 2 in a row. What I was suggesting was putting them in parallel, essentially giving 4 pipes for the 4 cats, then having the pairs of cats merge, giving a dual pipe setup.

They seemed simple enough to me, but perhaps I'm not delivering my ideas clearly.

The 1 about dual mode exhaust, at this point I only want to know where you can find a pair of z06 mufflers for under $300, which is almost how much a muffler and cutout is.

The rest require critical thinking.

The one about an EPS version of Pat G's Torque cam requires knowledge that I'm afraid only the serious "techs" possess, and they either haven't seen it or don't care. Pat G, Predator, J-rod, Tony, Random sponsor 43, those are probably the only ones who can help me on that thread, and I'm sure at least one of them has seen it and simply walked away.

VVT effect on DCR? same people, same problem.

I will agree that to the average person the "how to make a poor cam" thread makes little sense. (at least trying to figure out why you'd want to know). It's more knowledge for the sake of knowledge. As for giving an accurate answer? Same people, same problem.

The variable stall is advanced thinking, but you needn't have a "techs" level of knowledge to understand it. Honestly, it's nothing more than putting a 4l80e's 4th gear planetary in front of the torque converter (in the thread I say 1.3, but it's really a 1.33 gear).

And remember, what makes sense to someone is no more than their ability to perceive and understand the information they're given. I can understand not wanting to exert the effort to make sense of some of those threads, but few people lack the ability to do so if it were truly important to them.

 

What do yo drive?
Is it really "stock"
what are your plans?

 

Stock 2002 Z28 (might be SS, haven't checked the VIN).
I don't plan on doing the free mods, since most (other than the ram air) don't seem like they'll do anything. I do, however, plan on doing the "dirt cheap with acceptable results" mods.

-Ram air
-Lid (thought I saw something about removing the silencing baffles on the stock piece and making it flow the same as aftermarket lids). If I can find that thread, there's another $100 saved.
-Ported TB (if you have any threads with before/after results, those would be nice. If not, I'll find them. I plan on porting it myself, or finding a cheap one used).
-Full exhaust/poly motor mounts. Need cats for the local HiPo (he'll stop you for anything. If you even look at him he'll find something wrong with your car). Preferably Cutouts and near stock sounding mufflers as well, for the same reason.
-Maybe stall. That has a lot to do with this thread:https://ls1tech.com/forums/automatic...ble-stall.html
-Probably no cam, I'll do that at the same time I do the heads.

The rest of my threads are for future mods, requiring more money than I have available.
(if you're curious):
-Retrofitting VVT to my car.
-Turbocharger (hopefully, but it comes last on my list. Unless the price difference is less than $1400, a simple H/C/I will do). This is part of why I was planning on a cheap yet effective exhaust setup for now. Resale value in the aftermarket world is low, so no sense spending money on something that won't retain it's worth when there's a chance of getting rid of it in a matter of years.
-It has piston slap, so either new rods/pistons/rings and honing, or this:
https://ls1tech.com/forums/generatio...e-4-085-a.html
Forged internals for either option.
-new heads. if 3.905 bore, 243's For NA (ported or stock), 317's for FI. if 4.085 bore, or if I end up with a new block, and it exceeds a 4.00 bore, ls3 heads (ported or stock), NA only. (317's for FI)
-trans build up/swap
-rear swap. (I'll start a new thread for this question, but do you know if a gs400 differential can be used on a 4th gen?)
-stall/gears/street tires. Not many local drag strips, but some hardcore ricers that like to bet (even out here). The only problem is most of them actually do have engine mods (lvl 2 ricers), so I don't want to risk the humiliation. Anyway, street tires, probably big ones, but no drag radials.
-tuning: I'll probably be running the megasquirt 2 or 3, so I can utilize the VVT. I know the gen 4 pcm could also do it, but the megasquirt can do just about anything if you have the right inputs and know how to program (including variable stall, if I choose to run it).

Yep. So that'll come later.
