Anyone know which is the lighest aftermarket exhaust? I'd like to find something in aluminum....maybe I should just get custom welding and just a light weight muffler?

 

Really? No one has any input on a light weight exhaust set up?

 

Something in Ti. For off the shelf products, that would most likely yield the J's Racing 50RS. I know for the GE if one were to get all 3 pieces (front, mid and rear sections) the weight savings would be just under 19.5lbs. With just the mid and rear sections weight savings would be 13.2lbs.

 

if you get the j's full exhaust setup your wallet will have a lot of weight savings too.

 

I'd really like to just get the J-racing muffler (to me it has the nicest tone) and get a muffler shop to fab a 2.5" aluminum exhaust.

Is it possible to purchase just the muffler from Js Racing?

I know for my 2001 civic that the stock exhaust weighs 70 lbs!! An aluminum kit weighs 12lbs all together. Thats's a significant weight reduction...

 

Yes you can get just the rear portion. For about 1.5lbs more weight, you can purchase just the rear section in SS versus the Ti, but save about $300. The tone will not be exactly the same as Ti and SS have different sound properties (usually because of the wall thickness of the piping).

About going 60mm piping, wouldn't really do it unless you are going to boost. Really I think even going up to 54mm piping is going to hurt a little on the performance side in the meat of the powerband, for possibly a small gain at the very top. The L15 just doesn't have the flow to warrant bigger piping than 50mm in NA form.

 

How much weight has the Ti Exhaust of Mugen?

I'm collecting the different weights and sound files here:

anyone thought about a straight pipe for just the rear section? would it be loud? seems like a cheap weight reduction to me...not sure if it would be loud

 

I have a custom straight pipe.......in my attic
it is not lighter than stock, probably because of the sexy tip I chose.
The sound is good, some trailing throttle muffled pops

 

is the stock muffler not that heavy?

any pics? what if i chose aluminum piping?

 

It was like $1500 for a full titanium exhaust system for the GD3 in 2006. There was a post of one of the headers braking at a weld...It is a racing item and really to delicate for street use....

 

for non TI id go with t1r header and test pipe with spoon b pipe and spoon muffler.

 

I disagree, a racing item should be stronger than a street item. The car endures much higher loads on a track then on the road. I would assume it was just a bad weld.

 

Racing parts are designed to do one thing and and that is give a speed advantage and longevity of use isn't is much of a consideration as long as the advantage wins races...

 

Thats a far reaching blanket statement. If a part fails during the race your far more screwed. I've been racing long enough to know that when properly built the only racing parts you should need to worry about wearing out are tires, brakes, and engine components, everything else should be pretty damn reliable.

 

The Spoon N1 axle-back is pretty damn light. Had one on my DB8.

 

Well I am sure that since you've been racing long enough to know that I must be wrong. Have a nice day.

 

There have been some bad welds on some Ti exhaust parts, bad because Ti is tricky to weld.

 

Yes, and since there is a
Not for street use disclaimer, they specifically state it is for racing only and there is no guarantee on racing parts..... I wish I knew where I read an article about exhaust system materials, it stated that titanium was too delicate for street use and for racing only.... When I am talking about race cars I'm not talking about cars doing double duty and used on the street as well serious racers break things all of the time.... I have only raced and tuned off road motorcycles and do have first hand knowledge about all out racing and the expense of replacing broken parts and that motor, drive train repairs and overhauls are just part of the game if you are serious about winning.

 

I HAD a J's Racing titanium b-pipe and J's Racing axle back....way too loud as a daily driver and you'll never be able to tell the difference in weight savings anyway regardless of what the horrifically inaccurate butt dyno tells you.

Unless, you just gotta be that guy with one of the most expensive exhaust's on the block save your $$$ and do something that will really make a difference in actual performance...forced induction. Take it from someone that has BTDT.
