Performance gurus HELP!!! Exhaust question...
Disclaimer: I am a performance mod noob so some of these questions might sound stupid but no need for smart a$$ replies. Can't help - keep it to your self. Thanks in advance and a beer is on me for any useful advice.
Y pipe on my 2004 LS430 is rusted and leaking just past the O2 sensors on both sides and instead of buying an OEM I would like to get something custom made.
Question #1: I would like to get a custom exhaust made that would give me a little more power and MAYBE a little more sound keeping in mind that this is a luxury sedan so I'm not really looking to make my LS sound like a mustang. What diameter pipes should I use?
Question #2: For optimum performance does a custom exhaust have to start from the manifold? If it doesnt, can I just have a shop start with thicker pipes where the leak is? If it does can I use one of these http://www.ebay.com/itm/MagnaFlow-Ca...481826&vxp=mtr
put sensors in and do custom piping past that cat converter?
Question #3: There seems to be a lot more aftermarket parts available for the GS. Are there any parts interchangeable between GS430 and LS430 with the 3UZ engine?

Just head out to a muffler shop and have them replace the Y pipe with 2.5 inch piping. but it's your choice if you wanna keep the stock mufflers or go with a after market one. I'm planning to do a custom Y pipe and mufflers in a month or so myself. Hope this helps a bit. Keep your resonator it'll help keep the noise down a bit.

You won't improve on the stock y-pipe until you get into the 300rwhp+ arena. Realistically, you're more likely to lose response at the gain of sound.
