Hey guys i just want some feedback on your opinion for the best positioning for a cutout. I have a 94 formula 6 speed which is stock and i have a cutout im going to install shortly. What is the best place to put it without it being too obnoxiously loud i dont want too much police trouble. My buddy had his before the cat and it was really too loud i couldnt imagine when it hits 3500rpm+. His was an auto so the rpms were usually lower but in a 6 speed car when i get on it i dont want to it to be where its unbarable to drive with it open. I know some people put them after the front seats where the floor raises up and some before the axle/muffler.

Im on a short budget and dont want to get into a full exhaust this year but want to enjoy it and be able to step on it and put a grin on my face . Im thinking either of two options would be best but not sure how everyone else on here runs them.

Thanks,
Matt

 

Typically they put them right before the rear axel about a foot before it on the I-pipe.

 

First off, how the hell you going to run a cutout and it not be LOUD?

Second, I thought the best place was under your feet (right after the headers)... I thought the point of a cutout was for less restriction... The further back the more restriction...

IMO it would be a waste of money to put them on after the cats...

true duals dumped usually end before the rearend...

 

if you are trying to avoid pissing off the noise police, don't get a cutout...when you get on it- it gets loud.


I was going for loud, so I had mine right after the Y (no cat) and it was too much...I ended up only using it at the track to see if it helped.

 

Most exhaust shops put it where I said, other wise it will sound like **** and vibrate the **** out of everything.

 

Disagree. Mine doesnt sound like **** or vibrate the crap out of everything. Is it going to make more vibration then reg exhaust...yea...its a cutout

 

The common consensus is to put it where I said. Some people don't thats fine.

 

never seen it there! but if that common then i guess thats where it goes...

edit: maybe for dual cat cars (if you are still running the cats) you would put it back that far... because the one converter is so close to the exhaust manifold... 96-later
But for single cat cars you would out it before the cat... pre 96 cars...Make sense?

 

IDK if this will work but try disconnecting your current exhaust (if you can, your sig says custom) in each place and see how it sounds to YOU.

 

he's talking about a 94 formula 6 speed

 

do a ****en search and see for yourself, this isnt the first time its been discussed. Let alone the guy who has done it over hundreds of time and installed mine, said that is where he pretty much always puts them. (performance Exhaust shop)

 

you say "typicaly, common, most shops" yet i have never seen one installed after the cats...to say thats what most shops do is BS...
He wanted an opinion and thats what i gave him...
i also think that if you are going to run cats then your betteroff spending money on a nices light catback system like the slp lm...

Not saying your wrong... i just have a different view...

 

Take into mind you want some backpressure which is why a lot of people do not recommend putting a cutout right after your header. You need backpressure for torque and egr to function right.

 

I have my cutouts right after each header and still have plenty of torque

 

Back pressure is NOT needed! I don't care what anyone says, have you ever seen a racecar with anything other than headers? The point of a cut-out is to eliminate all restriction possible. The only place worth putting one is right after the headers or y-pipe.
