I'm giong to be diong a new exhaust set up pretty soon. Havent secided on a muffler yet. But any pros/cons to going with a bigger tubeing? Mine now is getting all rusted and old, and i want something new, that wont rust. Suggestions?

 

Don't go bigger than 2.5". On my 4.0L, she lost a little power. I'd go w/ 2.25" & a flowmaster 40 series. If you want a quiet mellow, but good sounding muffler, go with a flowmaster 50 series. If you have a good amount of green, get all stainless steel tubing. On a budget, get aluminized 13ga or 16ga tubing. The thicker, the better. It will last longer.

Good Luck!!

Whats the stock tubing size

 

Stock is 2.25" If your having problems with rust. Go stainless steel.

Im alittle biased on mufflers after having 3 different kinds, and 4 diff set-ups.

 

does moving up to 2.5 have any pros/cons?

 

I would say 2.25 Stainless......I have it on my 4.0

And as far as mufflers, Borla Tops anything that ive ever seen. (sound AND performance)

Take a look at the Borla Pro-Xs series mufflers, I have center/offset which is the shortest Borla muffler, which in turn is going to be the loudest (soundwise, comparable to flowmaster 40 series) But if you dont want all the loud sound, Borla makes the Pro-Xs series mufflers in various sizes (larger muffler = More quiet exhaust)

I got my muffler and tips from ebay, no problems or anything....If you want to get the muffler at its cheapest price, i suggest ebay...

Good luck!

 

does the borla sound more throaty than the 4o series

 

No, the flowmaster may be a little throatier because of the way its designed........but the Borla muffler sounds damn close.

 

on ebay i'm seeing the Borla pro xs...is that the one? Its okay to buy a used one?

 

I have only heard a Borla on Marks truck through the computor and I like the flowmaster on mine better. Marks truck I am sure sounds better in person as computers never do justice. As long as you buy stainless a used one should be ok.

 

flowmaster 40 series or a borla is good but you should stay with 2.25 piping... it is the best setup for a 3.0

 

I gotta represent the Magnaflow crew. I was gonna get the Borla too but there are no authorized dealers within a decent drive of where i am. From what i understand Flowmaster is all sound and no go. Plus you can't beat the warranty of the Magnaflow. I have a clip of mine if you wanna hear it.

Buying a used muffler isint going to hurt, if it was me i'd try and get a new one but all well, at least it may be broken in.

And trust me ive heard Flows on a 4.0 in person next to my 4.0 with Borla and its very close.

 

listen to my 40 series...its a delta though abit more quiet..its in my sig

 

Go with a Spintech Muffler... i got 2.5 inch tubing.. and its sick.. if i could get a clip of it i would...but dont know how.. sorry.. haha
