I had the same question...thinking about just running 2.5, thrush glasspack, then dump it out the side maybe....all my buddys like the thrush way better than cherry bomb but i havent heard either on a 4.0 in person...what is your take on them?

 

I love them they are loud and sound soo nice...but they drone...nothing music can't fix

 

If you decide to do it take a video if you could
I wanna hear it

 

X2

 

So 2.5 inch piping into a glasspack then straight out the back

OR

2.5 inch piping into a hi-flow cat from performance curve straight out the back

 

I think the glass pack will sound better

 

any more questions guys ?

 

Ya find me.a.header, cat and muffler for under 100$

 

I don't think you can go 100 ....maybe if your friends hooked u up with free parts...but no I think a good mix is a 60$ muffler 80$ hi cat. And 150 cheapest localy for your header.....the most u pay is 325 for all that

 

I'm thinking about building my own header.

 

Ive never seen that done...probly could work

 

Yes....

 

I'd sudgest a hi flow cat...but u need to take the high flow to put in an o2 hole for your sensor...also id recommend the flowmaster 40 or 44... If u want loud go for a glass pack...if louder then flowmaster 10

 

I've built exhaust systems... my dads friend builds custom stainless headers for classic race cars and rare customs... its not real hard. Just need the flange and the dimensions.... you could really go all out.

 

Hey if u got the know how then do it
