Yes to both. Adding a catted pipe will cut about 25-30% of the sound, and clean up the smell. I went back to a BBK catted X-pipe with my new build. I was sick of obnoxiously loud exhaust. Now I can hear the motor working, and worry less about drawing TOO much attention.

I actually went the opposite route. I had the BBK Catted X pipe. With that exhaust system, you didnt smell anything, except for when you step on the gas, you can smell the cats burning. It will defiantly lower the sound output and eliminate all the exhaust fumes.

 

i guess i just like my cars loud... always have. Esp once i found exhaust that is crazy loud outside and still civil inside.

as far as the gas vapor in your eyes, dont be a ##### hahahaha

 

i have a catless x pipe with slp loudmouth1 and its stupid loud.. dont use a handhell tuner go and get it put on a dyno and get it tuned correctly and you wont smell anything.

 

A catted h or x will be significantly quieter, but you will definitely still be able to hear a god exhaust tone. The cats will do a good job of cleaning up the unburnt fuel in your exhaust as well......that is after all what they are designed for

 

I agree with those above, but depending on what other mods you have done to the car you may benefit from a dyno tune...

 

I have a Bassani x-pipe with high-flow cats and it still has a little bit of an off-road scent to it. I don't think anything will ever clean the fumes as good as a factory set-up. I think the sound level will be similar until you push it to 3K+ RPM's. Overall, your exhaust will smell 80-90% cleaner. Your power level might even improve with high-flow cats.

 

How can you say you'll improve power with high flow cats? Infact you'll be losing some power by putting cats on. Not much but def not gaining any!

 

My main issue is that i have to go to school and the campus police are pretty hard. Also in California there is a huge fine for removing the cats. I figure the sound will attract them and the smell will be a dead give away. So switching to a catted midpipe would more or less eliminate the smell and cut down on sound alot?

 

Again.... Yes and yes.

 

do you think the exhaust will be quieter around 1500-2000 rpms? right now it is loud from the moment i touch the gas all the way through the powerband. Even with the slightest amount of acceleration it is LOUD.

 

Are you running chambered mufflers?

 

cats will quiet it down and will eliminate the smell... thats their job

 

magnapack catback. they are straight throughs

 

The cats will quiet it down at any RPM range so I think you'll be ok when you put them on. However, mufflers also play an integral part of how loud the exhaust is gonna be. I would install the cats and then see how it sounds. You can always switch up mufflers as well later on.
