I have done the muffler delete to my truck, but would like it to be louder and sound deeper. If I was to put the 4040xl in place of the CAT is it going to be any louder, and how much. Or should I just do the 4040. Surely someone has done this step by step and not just all at once.[/align][/align]Thanks Adam[/align]

 

I first replaced the factory muffler with the 4040xl,, it got a little louder, but not bad. I dropped the cat a couple months ago,,, NOW YOU CAN HEAR IT. It reallys sounds a AWESOME!!

 

put a 4040 where the cat was... you want loud, that will get you there and in my opinion, keep the most low end torque...

 

I don't want crazy loud I would just like it louder that it is now with the muffler gone and the cat still in place. So I would like it to be a little louder and would like it to sound better that it does now with just the cat. I afraid that if I put on the 4040 it will be to loud and with the 4040xl in place of the cat it will get quieter. I would think that someone would have done the muffler delete before they did the cat like I have and then did the 4040xl or 4040 and be able to tell me the differences?[/align]

 

well,sorry, cant help there. I did the mag/cat mod, then added the aero. the aero/mag was quiet compared to the no cat w/mag setup. the only way your really gonna know is to do it one way or the other...

 

The 06's have a resonator, so when u are planing to make changes u need to consider that.....

 

i called up aero the other day. they say on my 03 (stock with no cat) that the 4040 in place of the muffler will be loudddd and the 4040XL in place of the muffler will be loud when ur really on it and quieter then just crusining. i think i will be going witht he 4040XL as i want it to be loud but not rediculously loud. hope this helps

 

My '06 has no resonator. Cat and muffler only.
