Hmm I'd just buy a quick turndown from AutoZone ....but no it is ok if u do the muffler has air running out so it makes it harder for anything to rush in...you will be fine

Mine is exactly like this..right after the crossmember is my cat, then my muffler & then it dumps out just before the rear axle!
Love this..
No issue with mud or anything! Many people run like this, no issues!

Yes the reason I stated the turn down was just to add some protection to the inside of the muffler from mud or dirt from the road
And off road

Alright awsome thanks guys will do this 2m and add to my build!

I think the biggest reason for turn downs is so you don't cook your under carrige. Without them exhaust would go straight for it, or anything in its way...with the turn down it will hit the ground before bounching back up..in that time the exhaust will cool.
Turn down or no, the muffler is going to get water/griddy crap it in.

^^ This..

MagnaFlow did some dyno testing. There was a 1hp difference between straight pipes and a high flow converter. 1hp isn't even slightly noticeable.

Exactly they are now making cats to be efficient and run and flow like straight pipes

Gee oh Dee

Ringo, you have been told more than once by more than one member that removing the cat is against FEDERAL law. Because of this its is against forum rules to discuss removing or altering the cat. These are rules you agreed to when you registered.

Please review the forum rules and do your best to follow them. This is your final warning.

hey guys probably gettin a new motor soon, and need to know if there have been any proven performance exhaust, like with dyno numbers. cause im getting a mid 90's so my intake will be good but i know it deserves a header. but i need to know which one will definitively give me torque

Apn headder go to a shop get a 2.5in down pipe new hiflow cat Magana flow muffler with a 2.5in tailpipe out the back....
Best set up for max torqe and hp also drop in a cold air intake... Www.performance-curve.com that place will be your friend ..but u need to find a place for ur headders
