Hey all,

I just ordered an AFE Atlas exhaust with no muffler in 4". Does anyone have any comments on these systems? Should I have gone 5"? I have a Van Aken on my truck and that is the only mod other than the exhaust brake.

Thanks
Len

 

4inch is all you...REALLY...need unless your making stupid big hp i have a full 5inch and it does sound better but for the extra 100$ i think its a good call for a 4inch

 

Thanks, that makes me feel better and I doubt I'll be adding more power. It's already eating tires.

 

There is alot of 700-1000 hp trucks running 4 inch

 

Well it's installed and it's really damn loud, but not in the cab
