keep stock cat and straight pipe question

[09 arctic cat m8]

Hi i have a dodge 2500 5.7 and am thinking of keeping all exhaust system stock, except for just cutting out the stock muffler and putting a piece of tubing. Will i still have good back pressure because the cats are still there. Just wanting little better flow and a little more mpg. Th

Lol who pissed in your beer?

If I were you 09, I'd buy a magnaflow muffler. They sound really nice on the dodge.

Ok thanks for the feed back, just wondering why you guys say go with the muffler instead of just pipe and keep the cats, is the pipe bad to do.

straight pipe it put the exhaust thru the hood that looks good too

It's not bad to do, but I did that on my 03 ram, drove it a week, and put a muffler on it. but it's your truck, and totally up to you.

ya my friend has a 05 half ton hemi and he did what you are proposing. imo not only was it louder than heck, it sounds like sh!t. the cops were always giving him grief about it, and finally a noise ticket. you could hadly carry out a conversation in there.
i have flowmaster on my hemi, 50 series. sounds great. magna flow is great to.

Go to youtube and listen to some clips,. TBH straight pipe sounds like ass and inside the cab you are gonna hate it,.. add a CAI and you will park the truck. I had a 3"si/so Flo-Pro on my '06 hemi and it sounded good enough, plus with the CAI it gave me a headache pulling hills in Jasper,.. so I removed it feeling no lose of power.

What year is your truck? It might have a resonator on it as well
