ive got the 4040 aero turbine and im not impressed. Im getting my tip put on in about 2 weeks and was wondering if i should go ahead and get it cut off and go ahead and have the kitty scrapped too. What is yalls take on that? i had straight on my last exhaust w/no problem and really loved the way it sounded

 

I would leave the kitty in place and scrap the muffler, thats what I did. It sounds very good and doesn't void the emissions warranty.

 

Leave the cat, delete the muffler all together.

 

thanks for both of yalls input. im getting 6" rolled stainless tip to deepen her up a lil jus never been a fan of the cat converter

 

Just curious I was thinking about the aero, or MBRP (?) what didnt you like about it

 

i do like it dont get me wrong. i just wish it was a lil louder. i like to make a lot of noise and its just not that loud

 

MBRP cool duals suck because I have talked to other people and experienced that the hangers never line up. You will always have a problem with them staying in the hanger. But they look good for the time there in there. So scraped the duals and went to a straight pipe with the left overs. Love it couldnt complain with how it sounds and its not to loud on the freeway in the cab.

 

I removed the muffler and kept the cat. The noise is to loud for me towing when I am on it. Underlaod it is loud.

 

I welded the 4040L right to the downpipe and welded the cat on after that (right after I cleaned it out real well )... I love the way it sounds - especially since it has a SS turndown right behind the cab.

 

Does anyone have some sound clips of an '06 with muffler delete?

 

I just installed a 5 inch turbo back straight (no kitty)and it is "unbearable" to drive and I probably wake an entire town up in the AM. I am having Spintech custom make me a muffler to fit without cutting.
