i have a 6.0L and i need a new exhaust. i was wondering what is better for performance, a single 3" setup or a dual 2.5" setup? any help is great because i need a new exhaust soon...emissions

 

Depends on what range you what the power increase. Cant remember which does what but one will give you more low end and torque and the other will give more hp and top end.

 

Single 3" inch is better low end and dual 2.5" is better high end. I've had both and i know this is true. Both are good setups though if done right.

 

I was thinking it was that way but couldnt remember.

 

I have single 3" on mine, and IMO thats the way to go. I know dual 2.5 is good too, I just perfer the single 3"

 

MagnaFlow single 3". I love it!!

 

 

i have single 3". i call it corsaflow

 

are you going to get it dyno tuned in the near future? If some serious tuning is possible, you might want to go with duals. The greater power on the low end with a single 3" and more high end power with a dual 2.5" is to blame on the tune of the engine, and how the velocity affects your A/F ratio.

If you don't think you'll be tuning it however, i'd go with a 3" single setup or a Y pipe to a single in dual out if you want it to look all spiffy.

 

Well hey, ill be tuning mine after the pacesetter LT's install. If i go duals, i figured id buy the pacesetter Y-pipe and have the Y cut and dualed so the connection between the Y and the headers is clean and proper but i can still run the duals after that.

Would the duals be better for me if i am going to get a performance tune?

Anyone know how bassani mufflers sound? I have a guy thats selling some brand new for cheap and they are both 2.5" center center so they will work with the turn downs on my truck. Think it would be worth it to try them?
