^ Thanks Lakeside, I will definitely be purchasing it and keeping everyone posted , tt is just too far away and this will keep me happy for awhile hopefully by then we shall see a nice supercharger kit for the HR. ;-) p.m. me pricing for the pulley.

Sweet! I PM'd you about the pulley kit.

I have these. They are great and the car feels a little faster than before. However, don't believe that they're going to add 10-15hp, maybe 5-6 at the most but it varies if you have a tune. Just my .02.

What mods do you have not trying to be offensive in any way just asking if there is anything besides your signature list? Stillen headers and Bassani exhaust? Did you also put tp's/hfc's on yet or cai's?

I think if you have all three you should be looking a total of 15-20 whp easily.. minus the injen cai intakes. I did 279 whp @ Sound performance with only cat-back/intakes. (no tune)

279 whp + 7 whp (tp est) + 14 whp (header est) = If I break 300 WHP im good for awhile... :-)

300 whp + tune + pulley = 310-315 whp??

Remember some of us HR's are the last of the breed mine which mean's we have freak's lol.. Got mine Dec 08.. LOL i broke in the motor in perfectly baby every step of the way... im at 15k now running strong.. dyno's were done during 4-5k miles only.

Championship bench racing at its best......you can't honestly think you are going to gain ~30whp from headers, test-pipes, and tune (the pulley makes 1-2whp max).

Be happy if you are at 295-300whp with all above.....it is still a quick car.

what's the weight difference between the two?

Headers are awesome. Sounds great, looks.. can't really see them, power improvement.. YES. The negative Nancy's who say they are not worth it speak lies. They are worth every hard earned penny.

I'm really liking mine. They do heat up the engine bay a little more, so think about wrapping them with heat wrap.

Thanks man!

Any videos? pics? how long have you had them?

Search SG-Motorsports Long Tube Headers... 30rwhp alone, i'm betting while inflated we'd be looking at a good 22-25 around the board. They're going to make em for the HR too.

Not so off topic: Headers are expensive. Installation is pricey. They create power through the band... comes in at what with installation, 1600-1800$? Just ask yourself if it's worth it to you personally. If not, go with something else.

I don't think there's any point in denying they make power though.

Not in production.....Stillen Headers + Install (~400) is no where near 1600-1800. I wouldn't be surprised if the SG's are in the 2,000 range when they are finally available.

kakashishin

I only paid at 800, with install for my headers and I think I got cheated with that price. Where are you getting the 1600- 1800 number from?

Where are you shopping? I can't find these for under 500 shipped new much less installed.

To re-ask.. does anyone know the weight difference between the two headers? (stock vs stillen)

03threefiftyz

iTrader: (25)

Read much? I stated cost of stillen headers + install (~400) is not 1600-1800.

uglyduc

iTrader: (6)

What? Please re-read my question... and try to hold back the . I'm just asking where are you getting your dealz.

03threefiftyz

iTrader: (25)

I am not sure what your issue is? I am stating that the install for headers is ~400 PLUS the cost of the headers themselves. I never even made reference to the cost of the headers themselves. I don't know what they cost because they are a waste.

Ok, I mis-read what you said. No biggie.

I've seen the dynos, there is a gain, it just comes down to if the $ is worth the #hp you get in return. If it's a waste or not is a matter of perspective.

To some, 2K is chumps change.

Sorry, that reference was in CANADIAN PRICING for myself.

Lets do the math: Stillen headers approx 600$ from website not including shipping/taxes.

Lets say 650$ to your door.

Jet coating (probably a good idea) 200 plus dollars, probably a very good idea since anyone using them has noticed a rather large increase in engine bay heating.

650+200+450 = 1300$

factor in my canadian factor, i'd be looking @ pricing in that range, seeing as i'd have to pay more for shipping, duties and installation since labor here is more expensive than in the USA.

Pardon that pricing, that was in refence to doing it right (with jet coating). Using heat resistant wrapping would be my second choice, but would be less expensive than jet coating.

Installation of SG's long tubes also requires removal of the cats. You can't compare SG's pipes as headers alone. For the proper comparison you would have see the gain their headers made, versus what headers AND test pipes make on any other setup.

The SG car, also has Nismo cams, 272s IIRC. The gains seen by their particular car is not typical of stock cam cars. However, with that said, I'd pay SG $3000 for their headers before I spent a penny on any part from Stillen, or any other underdeveloped header from any other company.

Everyone defending the Stillens for the 5whp gain, that's just ridiculous, and I mean that without being offensive. Equal length is just marketing. They are right, they are all equal length, all equally lengthed out of our powerband. That's why its a pretty level gain throughout the range.

A properly lengthed header, should provide a peak gain range over a fairly short band of RPM, 1000-2000rpm, and STILL have the small gains (5whp) everywhere else.

Actually, from what I recall, SG's car was stock cam at the time of the header install, unless you would care to reference a post pointing to the contrary.

And stop talking about "equal length" as if it were the only determining factor in an exhaust manifold designed. You have pipe diameter, collector size, collector placement, tapered/expanded runners, etc, which all have a fairly large impact on performance.

Normally, shorty headers are a waste of time, but Stillen's consistent gains throughout the powerband show it to be a reason consideration for those who want more power.

Of course, I'm hoping your post above isn't just you blowing hot air. I expect you to back up all you say with personal experience and/or dyno graphs.
