I am considering QTP headers and catted y-pipe this winter. I am wondering how much louder my car will be. I drive the car everyday for work in the summer. I like the sound now and do not want headers if it will be much louder. I have a Hooker cat-back now with the rest of the system stock.

Thanks for the input!!

This is hooker with Kooks headers and cats. Kooks and QTP headers shouldn't be that much different. In the words of "JRP" use the search feature !

 

I appreciate the link. I have been to ls1 sounds before. It is hard to make a judgement based on a sound clip though. I was just looking for first hand experience from someone that had a hooker catback and added the headers and catted y-pipe. The difference in loudness between the two is what I am after.

I did search but did not find this specifically addressed.

 

mine isnt that much louder, and i have duals

 

hooker is similar to magnaflow, you can hear my LT' catted setup in sig. it was a very civil setup.

 

It is louder, but only slightly. Screams like hell at WOT. Do what I did go to an F-body gathering/Dyno day, and ask someone w/headers to take you for a ride in their car. Then you can judge for yourself.

 

I had a flowmaster when I added my Longtubes. My car was actually a bit quieter at start up and cruising, it seemed, it definately wasn't louder, but was deeper and smoother sounding. But it screamed at WOT. I have a Hooker catback now and you'll be pleased with it's sound and performance with the headers, I am.

 

You will be fine adding Headers and especially the catted Y pipe. I daily drive my car also and it fits the bill perfectly. Stick with Cats and you won't have a problem.

 

The Hooker really comes alive with headers, but its definitely tolerable for a daily driver.

 

I had a friend with no cats and a huge cam and the sound was not bad. With cats, you should not be too much louder.
