HKS Exhaust Choices - Which one do I go with?

It will, I have already seen that combo, but it does not looks good for me, since the HKS quad tips are smaller and shorter than TRD.

Just read this whole thread as im bouncing between the two Spec L systems. On the first page it lists the weights
Titanium Tips - 27lbs
Carbon Tips - 34lbs


Looking closely the system with the Carbon Tips Has a longer Canister which would explain the extra 7lbs and the 3 lower db.
The Titanium Canister is shorter with a longer tip.


I like the look and extra suppression of the Carbon one better but do I want that extra 7lbs???

Are you a professional racecar driver? If not, you won't notice it.

Don't want to hear that weight reduction is very important for a vehicle like this with low power. Every little pound adds up in the end. Already about 87lbs lost from Wheels/tires 24, Pulleys 5, Front bar 15, Windshield washer removal 6, Spare/tool removal 31,UEL Headers+Overpipe 6lbs .


Not a professional but do a few HPDE events.


Back on topic just wanted to point out the difference between the 2 Spec L exhausts is more than just the tips.

Let me guess. That 3% weight reduction turned it into a Porsche. I'm not arguing that reducing weight isn't beneficial, because it is. It's just that the vast majority of people will never be able to notice a difference. Making all decisions based on weight is silly. You won't notice 7lbs, but you will notice the way it looks and sounds. You mod your car however you want, just offering perspective

No way in hell if the weights on the the first post are right would be adding 20lbs.


I already have Tomei UEL+overpipe, am convinced to go with HKS Dual Resonated front pipe. Looking at all options for catback. Want to stay with 60mm(2.36") piping all the way through after reading this thread on exhaust velocity http://www.mikekemper.com/elantra/diyexhaust/ which most of the HKS catbacks do. No single exits my car is DD with occasional light track so need to keep things civil. Want to lose some weight with the exhaust most only seem to be about 5lbs or so less than stock.

Diet and exercise will help out on the weight loss too lol. And believe me I don't notice the weight in the slightest. But if light is what you want go with whichever you like!

Its about power to weight ratio I can live with your opinion of it being silly. Every car build is different didn't go hardcore with weight reduction in the Vette because its easy to add 100hp to the LS1. Not so easy in this car without FI which I don't want to do. Weight affects all areas of performance - Handling, Acceleration, Braking, MPG, wear and tear on parts and feel.


What I did was only the beginning as Ive only had this car for 3 months. Still will lose weight with front brakes - 32lbs, Lithium Battery 25lbs, CF driveshaft - 10lbs, rear beam 10lbs, Rear seat delete 20lbs. Another 100lbs of precious weight lost right there without hurting stock drive ability and still have AC for cold days.

Lost 15lbs since the winter had to limit beer to twice a month though

SuperTom: if you go for maximum lightness .. also stock seats are rather heavy vs bucket seats. Some may be saved on rear LCAs such as Velox, though those are advisable mostly for camber adjustability they bring anyway. Then all that stuff including spare in trunk .. i wouldn't just remove it for emergency cases when DD, but on trackdays prior going from pits to track - why not? Then obvious sound tube delete (too little to save, but won't hurt functionality). Also lighter aftermarket exhaust. Further lightening via eg. soundproofing/trim removal imho affects NVH/DD comfort too much.
There are also bits that while can be removed with ease, but i wouldn't, eg. air drag reducing body plastic underpanels, or i'd even add weight in way of oil cooling rad/oil cans/airducts .

Thank you for this post I'm glad you didn't call me silly Wouldn't say I'm going for maximum lightness or I would just rip everthing out. Car is driven 100 miles a day to work so it has to be reasonable plus its brand new. Just want to add lighter parts when I have the opportunity.
Have done other things just didn't list them all I will address your comments
-I really like the comfort and support of these seats so will stay for now.
-Went with Racer X on my LCA's which didn't save weight but needed the ease of adjustment while on the car. - couldn't get a direct answer if the Velox did or not, Saw people cutting the frame for more room?
-Took all the spare stuff out but forgot I added in 5lbs for a small pump and a can of fix-a-flat.
-Got a Perrin pipe so got rid of sound tube and a resonator -2lbs!!!!
-Exhaust is what I'm working on now want light but bearable So no straight pipes
-Keeping the sound deading so far, Ive scraped the tar off my old 3000gt before and got 15lbs worth in a bucket!!
- Agree with keeping all the bottom undertrays as screwing with the stock aero would just cause drag - learning about how the cannon style mufflers could hurt the rear aero on this car.
-Exactly not doing anything to add weight, no coolers, extra bracing unless I find I really need it, No Heavy BBK with heavier 18" wheels. No heavy FI kits.(At least for now)


Here is a quick file ive been keeping track of weight reduction with.

Got one! Had to go back and reload all my pics with imgur as photobucket tried to rape me. Most people enjoy my interior pics its seems. Weighed every part replaced with a picture to keep track for any other weight reduction junkies
