Why is the Corksport stainless steal single exaust so cheap?!
The websight doesent give the diameter of the pipe but it looks damnn nice

 

It alsodoesn't list grde of stainless, wall thickness. Just remember you get what you pay for

 

It's a 2.5" flange that immediately flares to 3". Muffler has a 4" tip. It's made of polished 304 SS.

Yep, you get what you pay for - a damn good exhaust at a damn good price.

Looks pretty sporty to me!

 

Youd be stupid if you shelled out the money for an N1 when corksport makes their exhaust...

 

i got what i payed for, an outstanding exhaust system.
its top quality, a hell of alot better than just about everything else ive seen out there.

 

Well that is really interesting cuz im about to buy a apexi gt which costs 590 its really nice
It starts out at 2.5, then flares out to 3.75" with a 4.6" tip and full stainless steal but id buy the corksport to save my self some serious money if it compares at all to the gt

 

in all honesty, they are the same damn thing. get the corksport.

 

hell, i think the corksport is much closer to the GT than it is to the N1. it has almost no bends in it, just like the GT.

 

I found another difference though, the corksport doesent have the premuffler that the gt has i just noticed that in the pic on the websight maybe that accounts for the 300 dollars but isint that only to silence it a little? a stright pipe like the corksport might be better cuz its got no restrictions, damn this is getting me thinkin

 

yeah i think that it is just like a resonator or something. corksports the better deal, by leaps and bounds. i think it looks better, and i think it sounds better too. plus it is half the price.

 

Man, im planning on getting that exhaust. It better not have a 2.5 flange. Ive got a 3in DP, and a 3in high flow cat. That would suck. Ill have that **** chopped and FIXED.

 

since they make it, maybe you could have them make yours as a custom, 3" flange, 3" pipe, 4" tip

 

Just have that bit cut off. It's still cheaper in the long run. I've had my CS cat back with 3" RS*R frontpipe, and "custom" POS midpipe for over four months now. I love it but I'm going to be replacing the midpipe with a Magnaflow 5x11 muffler. This will require that 2.5" part to be cut off. It'll be nice to have a true full 3" system for bragging rights. Plus it'll take it down a notch at idle. But to those that whine about the 2.5" part : zip it! This is the best system for the money (or even more money). When you get yours in the mail you'll know you got a sweet deal. Also, to have the 2.5" part be the performance bottleneck you need to be putting down some SERIOUS power.

No one is doubting the Corksport is a good value for some. But it is not the answer for everyone. What wall thickness is the tubing? How much does it weigh. Where are the dyno sheets to show how it affects power, and TORQUE (More important to me)

 

banziatoyota: I just don't get it. Really... what do you have against corksport? They offer a killer exhaust at a killer price, and you still seem to think it's crap just because it's cheap? What, do you only shop at Old Navy and The Gap, too?

It's 304 grade stainless. Wall thickness is rather unimportant, really - even if it's 5mm thick (which would be ridiculous) you'd only lose 3/5s of an inch on the inside. If you're making enough power for that to be a restriction, you should be buying stuff imported from Japan or having completely custom stuff made.

It's lighter than the stock exhaust. That's all that matters. If you want something that's only 5 lbs, you need to be thinking about titanium and carbon fiber, not polished stainless.

...and dyno sheets? Power gains are going to be affected to a MUCH greater degree by many other things. Catbacks make very little difference, in the end. For the most part, they're all the same. Think about that. The biggest selling factors for a cat-back are looks and cost, because they're all essentially the same.

Sure, it's not for everyone. If I were making over 400 rwhp, I wouldn't be considering this catback. But I don't. And you probably don't either. And anyone who does isn't even considering this catback.

(Oh, and FYI, torque is power, and horsepower is work - an increase in horsepower is an increase in torque. Don't make me get out my Physics book.)

If you want a system based on looks and price, yeah, buy the corksport. Just because its cheap, shiney and loud does not make it a good exhaust. I have seen no proof that the Corksport does/doesn't do anything for the performance of the car.

The design of the exhaust system will greatly affect where peak torque occurs. I cant remember if it was Carrol Smith or Smokey Yunick who said"Horsepower sells engines, Torque wins races"

"(Oh, and FYI, torque is power, and horsepower is work - an increase in horsepower is an increase in torque. Don't make me get out my Physics book.) "

Yes, in general terms your statement above is correct, However; the design of the exhaust system will greatly affect where peak torque occurs. 2 differenet brands of headers and exhausts systems mounted on the same car will yield different torque curves. Proven fact.
I want a system that will help the NA out of the corner. I don't drive my car at full throttle everyday, I do however accelerate from the stoplight, out of a corner every day. I NEED/WANT TORQUE for my $$$$$$.

Why spend 300 on a system that I do not know what it will do? Why not spend 500 on a system that you know what it will do?

All of my research and discussions with engine builders indicate that a NA on the street doesn't need anything over 2 1/4" OD. Wall thickness is important to me from a longivity standpoint and a sound dampening standpoint. Ever hear a thin wall system and notice it is "TINNY" ?

 

These are the problems I see with the Corksport exhaust -

- No presilencer, like the N1 or N1 GT. That presilencer takes a LOT of bite out of the sound, but still flows well.

- No super silencer option. Yes, loud exhausts are mighty fun (I've got the N1 GT series, downpipe/midpipe, and open air vented wastegate (as in, a 2" pipe that goes from the wastegate to the ground - VERY loud)) but there are times when you don't want a loud exhaust, like on a loud car trip. Listening to your exhaust drone at 3000 RPM for 6 to 10 hours gets REALLY old REALLY fast. I've actually got out of my car to fill it up and my ears were ringing! That's the beauty of the super silencer - pop it in the exhaust tip, and it takes ALL the bite out of the sound. NO DRONING. The Corksport exhaust doesn't have that option, and it's not compatible with the N1 super silencer.

Now, I'm not saying I don't like the Corksport exhaust - that's a helluva bang for the buck! But, IMHO, I would spend the extra money for an N1 (about $425 or so).

BanzaiToyota, you're talking about maximizing torque and proper exhaust size. If you're serious about that, there's only one way to go - LOTS of money. You're gonna need some serious dyno time and try out different combinations of pipes and sizes to get what you want. Or, get something like the Mazdatrix full dual exhaust - again, big money. The Corksport exhaust is basically a turbo exhaust, but I've seen N1's used on NA's with GREAT results. Matter of fact an old roommate of mine had an RP downpipe/presilencer and an HKS 50mm cat-back on his '90 GTU. Replacing the HKS cat-back with an N1 made a difference across the powerband - bottom end felt great, but the top end was a LOT better than before. I think the smaller exhausts are a bit too little for NA's with the later s and/or intake manifolds.

BTW, on the stainless steel thing - my old N1, which I bought probably about 4 years ago and sold to a buddy when I upgraded to the GT series, is still going strong. There's some light surface rust on the piping, but nothing to get worked up about. If you live in an area that salts the roads and the like, go stainless. If not, don't bother. The N1 holds up REALLY well - it's a very well made piece.

 

Thats true: Speed costs money How fast do you want to go?
