Default Turn downs,Enough back pressure???

On my 2000 WS6 M6 i want to put turn downs on it that dump right before the rear end.
Will there be enough back pressure there?

Wut kind of bullet mufflers should i get if any?

Anything else i should be concerned of?

I have SLP LT's and SLP loud mouth 1 on it now, but its just not loud enough.

Back pressure is never a good thing. The less you have the better.

Yeah, needing backpressure is a myth. Less backpressure = more power. If this wasn't the case, no one would bother changing out the restrictive stock exhaust. You'll be fine.

LOL I am sure that loudmouth with Longtubes and Off-Road Y-pipe will be louder than True Duals with bullet mufflers maybe true duals with no muffler would be louder

I dont know how that isn't loud enough. All your going to do with no muffler is make it obnoxiously loud with no tone to it. Do you like attracting attention from everyone around? Including police?

You need NO back pressure.

I HATE it when people feel like their car has to be the loudest thing on the planet...what does it do for you? After a certan point it doesn't make the car any faster, just makes you look like more of a moron.

my duals w bullets and turndowns get lots of attention. even old people like them though. young kids, relatives, friends, strangers, hell even neighbors love em. it draws people in for some reason, a lot more since i put a cam in. not saying its like that for everywhere but here it is. no attention from cops as long as you dont act like a dumbass.

my true dual set-up is not as loud as when i had the slp lt's and the lm1. if you just want loud just buy the loud mouth 1. or you could even do a true dual set up and use 2 lm1 mufflers?? just a thought. but personally i think it will be way too much.

Correct. It will not hurt a thing. The *** of your car may get a little dirtier than normal.
