Ok guys need your help quick I am about to order my muffler but cant decide if I should go with the 16" Oval muffler or the 15" Round muffler I will be running it catless with LT pacesetter headers I am looking for performance and sound.

 

i know that trever1 has xr-1s on his truck dont know what size if it were me id go with the round id say it would be alittle more growl cause its a shorter case

 

i run 2 xr1 race mufflers, true dual, 4x15

you running a Y pipe?

 

mine are 13" ovals. They sound awesome in boost but just cruising lack a deep tone. I do have cats though. A bigger case will sound better imo.

 

yes with a y pipe muffler will be 3" 1in 1out

 

i had the round xr1 and it sounded good but i had cats at the time too

 

i would think about the XR1 its not a loud muffler at idle but sounds really nice at WOT. but thats my opinion

 

thats what im looking for im just debating between round or oval

 

id say go with the 16" oval.. i think it will have a nice tone without the cats!

 

I have the 13 inch body oval XR1,I like them very well.
