1996 ls400 undercarriage picture of stock exhaust
I have a brand new greddy exhaust for a ls400 and i want to see if it fits my 96. It has a flange after the first y pipe and as memory serves the 96 doesn't have any flange after the cats at all right. Unless it was made for a either the 1ls or 98 and up. If anyone has pictures of the exhaust alone that also works too. Thank you!

I also got a line on a sweet exhaust for a 98 GS300 that I hope can be moded to work on my LS400. The setup comes with two mufflers and a y-pipe and it looks like the y-pipe will fit in place of the mid-silencers on the LS. Of course a flange will have to be welded onto the factory end so the bolt-on will work. If it works out I will have the shop also add a flange to the factory pipe I am removing so I will then have a true bolt-on/off system where I can swap them back out come CA emissions time. Got a link to any posts with details in the forums where others may have had some success with this mod? Thanks.

Length is easy to fix by adding additional tubing. Not sure what you mean by the bends being different. The new muffler inputs appear to be bent nearly identical to the stock ones; even the hangers are in the right place. From there it's a straight shot to the y-pipe and on to the CAT tubing. But let's say you're right...what would you recommend for an exhaust upgrade since outside of Japan there are almost no bolt-on systems for the LS series under $1,000? I am just looking for an agressive tone and better styling and don't really care for the arguing about "if your tubing was .5 mm bigger you could gain .75 and 9/10ths torque increase when the car is upside down under water" or any other such nonsense I've been reading in the other threads. Maybe some after-market straight resonators with custom pipes from my local exhaust shop is the way to go rather than hopeing a $400 GS400 exhaust will work?

and an exhaust shop of your choice. have fun. I recco a 2.25" pipe from the cat's back, with an x-pipe to aid in scavenging. if all you're doing is the rear section, then a couple high polished magnaflows will suit you just fine.
i don't recco bolt-on systems for the LS because frankly there aren't any that I like or feel are worth the money.
also, you can run whatever exhaust setup you want for smog purposes, provided the headers and cats are OEM or CARB-legal.
i've never had a problem with SMOG in the past 5 years i've had my exhaust setup on the car. (cops on the other hand...

Thanks, PD. And that's a good point about smog because as you know the rear section (all sections?) of the LS400 exhaust is flared and clamped together so adding new piping/mufflers means welding them together which would pretty much prevent you from reinstalling the factory mufflers anyway. So when you did your setup did you remove the mid-silencers or just add the new mufflers?

I had mine done a local muffler shop. I had from cats back done , deleting the center resonator/cat(17410). Using the the resonating mufflers (17420), and a set of Greddy mufflers (00ish Accord i believe) to finish out the back replacing the stock ones(17430). just louder than stock but has a great aggressive tone.
depending on who you talk to 17410 is a cat or resonator, 17420 is a resonator or muffler. I had one shop tell me that legally the could not chance anything before 17420 because it was all part of the cat system. So even exhaust shops will give you different stories.
