If you put it behind the cat it won't be as loud, but then you're sacrificing performance. That is if you have a cat...

PUT IT BEHIND THE CAT!!!!
when i went to get mine put in the shop where i went missunderstood what i said and put it in in front of the cat, in the Y PIPE... and it sounded like Sh*t... it was absolutely too loud... and didn't sound good until i got in the 3000 RPM range... behind the cat will sound better and now be as loud... i have heard them behind it in the middle of the intermediate pipe... i like the sound.... IMO

Don't be gay, put it in FRONT of the cat. Cut-outs are for hard core racers. If you want it to sound pretty get a hooker cat-back.

Cut outs are meant to be installed as close to the header collectors as possible.The purpose of having them is to bypass all of the exhaust system to rid any restriction from the engine's ability to breathe,why would you want to put a cut out after your cat?To each their own,it's your car..but I would always prefer to have it before any exhaust (cats or mufflers) to free up as many ponies as I can.Granted a stock cam with open headers (or worse yet manifolds) doesnt' really sound good at all till you get a little rpm's in the engine.I installed mine in place of the long deceased cat.It is usually open more than closed..love that cam thru open tubes.

putting it behind the cat defeats the whole purpose. they are made to cut off the whole exhaust for maximum performance.

well my cat is hollowed out, i was wondering if it was put a little futher down steam on the exhaust maybe it would not be quite has loud. i have driven the car with the cat back removed and the hollowed out cat and it was way to loud, so i thought maybe with it further down steam and the exhaust gases having to go through 3 more feet of pipe it might muffle the sound some what. so my question is, will it?

I wouldn't think it'd be enough to notice.

Here's another question about a cut out.. I think in PA here, your car won't pass emmissions if you have a cut out, even if it's not open. How are you guys passing emissions?

think again. put it underneath the car like mine, and you hear it like a **** inside and out. place it at the back near the axle and you hear it more outside of the car.

Mine is also under the passenger seat. It sounds awesome... but a bit too loud for cops. I will be investing in a MPPII this winter.

Try www.quicktimeperformance.com/qtec.htm for electric cutouts. They are high though. Makes getting under the car to open them up a little easier.

my brother has a cutout on his ford thunderbird turbo coupe, he just takes out the cat and bolts in the cutout; sounds real mean at any rpm, all you can hear is the turbo spooling
