My mustang isn't poppy AT ALL!

 

The "poppiness" is more related to lack of fuel than the muffler I'd imagine. Mine isn't poppy at all... It is quieter when driving than I imagined it would be though.

 

I'll try to get a vid up tonight if my camera has batteries.

 

Maybe tomorrow morning. Don't want to wake the neighbors. LOL

 

Haha alright...i wanna hear it on a 4.0...so post it up lets see if you can persuade me that its better than the 10 series

 

I don't know if it's better. I'd never heard one on a 4.0 before so I bit the bullet and got it instead of the super10 lol.

 

For now it is going to be dumped before the axle. I'm thinking about getting the 2.5in muffler-back pipe that mudfrog sells though

 

Oic ic. Well thanks for being the test dummy.lol if only u did it before I ordered my other 10 series.lol

 

good thing i found this thread

there is a lot of info here but too much for me to read, hopefully you guys can help me out. I recently bought a 1998 classic 4.0 and need to start doing some work on it and the exhaust hangs down a little where the cat and muffler meet, also right where the exhaust connects to the exhaust manifold the lower half is kinda bent. so what i wanted to do is change out the whole exhaust from manifold and down. I talked to one of my buddies that owns a muffler shop and he told me he would charge me 150 to custom bend a new exhaust system and if i buy the new muffler he would just throw that on while he is doing so, he told me to buy a super turbo dynomax muffler because of its performance. Im not too sure how they sound but he said the performance is pretty good (i want something with a deep sound).

my questions are
1) is that a good price?
2) should i go with that muffler?
3) is there somewhere online where i can order the exhaust pre-bent?

 

That's a good price if he is doing the whole thing from the header back.
Look on youtube for sound clips of different mufflers. You want it loud or quiet?

 

Dont want quiet and dont want too loud, i want something about 3/4 of the way to loud, i heard if you want loud it doesnt sound that nice so i rather get something a little lower and sound nice. get me?

 

I was wondering if u delete the cat what's that's going to do to the 4.0? Also have u ever heard of the down stream o2 sensor having a short?

 

makes it illegal.

You won't notice any improvement anyway over a standard "high flow" cat.

 

For anyone wanting to tuck their exhaust system up its do-able and I have done so. The stock exhaust hangs below the "frame" rail by a solid 2-3". Mine sits level with the "frame" rail, the lowest part of the entire system is the tip of my turn down
Here are some pictures of it, sorry they were taken at night. Pics where no exhaust is showing were taken level with the bottom of the "frame" rail

 

mine sits about 4-5inches down haha its like a v
