Went to my exhaust shop, and was talking to them about a custom setup. he said the best option would be just to "straight pipe that son *****." i know it sounds redneck, but i was thinking of cutting the cats, resonator, and doin 2.25 inch piping into flowmasters mufflers

just cut everything from cats back and replace with xpipe and 2 mufflers.

Cutting off a cat doesn't do much unless you are in boosted situation. A Magnaflow cat will do just fine.

Don't do straight pipes......you lose to much low end, and after a few weeks the obnoxious sound gets to you. Don't believe me? Check my myspace for the vids.

^I dare ask if you have a sound clip of that?

vince1128

so you lost power without the cats?

also, what the model number for the ones i need

nismo2trd

one resinator, sounds like a domestic V8 with cams.

can you just partially hollow out the preconverters, leave single big cat and the resonator?

and keep a descent sound also does your check engine light come on?

It might cause you problems with emissions (if you are in NoVa...I used to live in DC However, I pass some pretty stringent Mexico City emissions (voluntary for foreigners, but it gives you some benefits) on 1 Magnaflow cat without precats (1destroye by $#*!@ gas here). I have had no CELs, but not sure about anyone who has run this set up in an SC400.

Gutting the precats is a common thing in the rest of Mexico...in fact gutting the cat due to MPG, but this is on small vehicles like VWs/Nissans.
