Right now Im trying to get pipes made so I can remove my catyolic converters.
Lord of the Celsiors is running straight pipe...... his is still running good if it wasnt he would of put something back to help with the back pressure.

I am actually leaning towards dual pipe set up, after my custom cat back parts, plumbed into my existing rear mufflers. Those mufflers are so easy to remove I can do it at the strip for back to back testing. Also, I intend to place pressure probes at various points in the system. Since I will be replacing EVERYTHING from the cats back (except for the rear mufflers for now) I will have a chance to do a variety of tests... I like having good reliable test information.
NOW... PLEASE... ONE MORE TIME... to other peoples posts in this thread... engines do NOT need or want backpressure. This is an incorrect assumption made by people with partial information. It has been said so many times that many people just assume it to be correct. The PROBLEM is that large pipes LOWER velocity. It is the loss of velocity that hurts low RPM power. The solution is to build the best flowing lowest restriction system from the smallest diameter pipes cabable of supporting the high RPM power output of the engine. This is why I recommend 2.25" pipes and not 2.50" pipes. So please, everyone, stop saying an engine needs exhaust backpressure.

example sc300.... inline 6, n/a, 2.5in from the header (ex: xerd header) w/o cats back would be perfect
same only with 3in not good loose power

i just did this mod (thnx to lextreme's guide) and it sounds MUCH better. only thing is, to anyone who has heard an LS w/o rear mufflers, IS IT TOO THROATY??
i ask this because i am 16 y.o. and driving my own lexus. the last thing i want is to have cops all over me.
also, just to make 10000000 percent sure, this mod IS legal in SoCal? RIGHT??!?!
sry, just some random confusion.
thnx in advance

this states that a car has to have a muffler.
now, since the car still has the silencers and center mufflers on it, do those get counted as mufflers?????????
if they dont, im putting the stockers on this weekend and looking for a cheap used exhaust.
