MUFFLERS.

I just sent an email to everyone on the commitment list info on a fantastic deal on stainless steel mufflers I have located.

If anyone is planning on a full exhaust upgrade PM me and I will send you details. This would apply whether or not you are interested in the headers.

 

John,

I may be able to get some free time in the next few days to bring my 430 by for you to look at. Did you still want to take a look?

TXGS way to step up to the plate.

 

I just spoke to TXGS, he has a GS430 and is going to join me and a couple other CL members this weekend for some testing. With luck we will be able to trial fit the GS430 Y pipe to a GS400. We will know much more after this.

 

Hopefully we come away with some answers this weekend. Good or Bad!

 

Can you post details here regarding this exhaust upgrade? As you know I am interested in upgrading/modding my exhaust purely for sound effect with minimal to zero loss in power on the bottom end and am wondering what exactly this exhaust will do. I currently have the stainless L-tuned mufflers and would like to keep those, but change everything else.

 

Please PM me and I will answer offline.

 

Might be a bad ??? but think you can get me a set for an RX330 ???

 

Let us know how the fitment goes, thanks !!! (GS430)

 

For all the early 400 owners, who's planning on completely removing their EGR system?
If you are, do you have source for EGR block off plate? Can you (Jbrady) fabricate a set when shipping out the headers?

 

patiently awaiting the result of the GS430 test fitment

any word on this?

 

Unfortunately my spousal unit does not share the same enthusiam for the automotive world that I have. I was only able to stay a couple hours for the fitment test. I have not heard from jbrady on the fitment test on the GS400. Hopefully all went well after my departure since I wasn't able to supervise!

 

Well, the GS400 and LS400 Y pipes are NOT compatible. The catalyst downpipe angle is SLIGHTLY different. As TXGS mentioned we did not get the chance to check the GS430 against the GS400. Maybe we will get another chance.

Here is a picture of the LS400 Y pipe sitting on top of the GS400. They are so similar you have to look very closely to see that there are in fact 2 in the picture. The angles around the transmission are identical. It is the angle of the cat flanges that is slightly different and of course the length of the center section.

 

So if the LS4 and the GS4 y pipes are diff than custom y pipe there to right? When TXGS and you gona test the 430 still got my fingers crossed.

 

Actually all of these cars SHOULD run a higher capacity Y pipe to get the most effect from upgrading the headers. That said, the GS400s will NOT need a custom Y pipe to actually fit and function. It is just better if they do. It would have been nice if the mounting of the LS400 and GS400 were the same as then one custom pipe could have been produced for both cars.

To confirm on the GS430 vs. the GS400 I will want to test fit the 400 Y pipe to the 430. If that fits I want to test fit the 400 cats and Y pipe on the 430. That will confirm fitment. However, all of these cars need a Y pipe upgrade. Anyone wanting these headers should plan to at least some point upgrade the Y. If you have a GS430 or other 430, and really want the headers, my recommendation is to buy them now. Wait until another 430 owner who plans on upgrading the Y pipe anyway does so. Once that is done we will know if the stock pipe fits or not. Worse case scenario is you decide it is not what you want and you sell the header to someone who wished they got on the first production run when they had the chance. Truthfully, this is a small risk reward ratio.
