New Y-pipe = Headers???

[squee]

Don't exactly remember the graph, but it was pretty much better over all.

[slp1122]

Texas Speed had a deal with their long tubes and Y-pipe a while back. I think it was like $500 shipped to your door.

yea i would that that, they have an AWESOME y pipe that comes with the kit.

I still think pacesetter is the way im going

[Blackbird WS6]

lpparts.com, $600 headers and y pipe Stainless Steel, some people on here have those and like them check them out if you want

[Smokaholik]

I have a 01 WS6 with a k&n cold air, 160 thermo, billet maf, flowmaster exhaust, & cutout. looking to get a great pair of headers so you'all say 1 7/78 is more power than 1 3/4?

[mpfranks]

Yeah Im going with them I think
I just need to figure out what all I need

to answer you question youre gonna need the headers, cats (depending on your preference/state emission laws), y-pipe. and to get rid of the check engine light some sort of tune, either handheld, dyno, or mail order tune.

and something else to think about would be some new header bolts (stage 8 maybe, about $40), band clamps, and might wanna do a tune up while you got the manifolds off.

kinda adds up by the end. its not gonna be just the $400 for the headers. might wanna look into all this before you pull the trigger.

Wrong...TSP did a dyno comparison on a stock motor with 1 3/4" vs. there 1 7/8" and they gained something like 15 or 17hp and only lost 2 ftlbs of torque. Like thats even noticeable. 1 7/8 is the way to go even on a stock motor.

This is correct. I've seen this done before, TSP wasn't the first. I saw this a couple years ago, I think it was Chevy High Performance mag that did a back to back comparison. 1 7/8 headers outperform the 1 3/4 headers even on a stock LS1.
The entire curve was slightly better. The difference on a heavily modded LS motor would show even more.

What do you mean by tune up?

[tav8ws6]

I believe Supermaxx long tube system is pretty good too isnt it?

[basballny2]

What do you mean by tune up?

maybe he means plugs and wires? not sure what hes talking about either.

Ive never heard of supermaxx to be honest.

[0verkill]

the texas speed headers are nice i just put a set on my ta. only thing i had to do is get the y bumped out some to fit over the headers. and it comes with band clamps.

[tav8ws6]

The Supermaxx headers are made by Dynatech. They were featured in the November 2008 issue of GM High-Tech Performance. They made 25HP and 21 ftlb of TQ with high flow cats. Pretty neat looking setup. The magazine ranked them pretty high.

What do you mean by tune up?

yeah i mean plugs and wires. its easy to do a tune up during a header install. if it hasnt been done, or needs a tune up, prob wanna just do it

Pacesetter headers (off-Road) with an off-road Y-pipe kit is the way i'm thinking about going. Opinions anyone?

[LT1 > LS1]

I'd go with LPP headers

they arent much more money, and they are stainless, stepped, and have awesome collectors

[99TransAmSLP]

that is what I thought when you said tune up mine already has the new wires and stuff
