catback exhaust for 4.0L ohv

[Critical_Level2]

Glass packs can be very very loud, everyone will hear you coming and so will the cops.

i'd like to add you should keep your cats also

word is you aren't gonna see the performance gains you might think by removing the cats on an explorer, and frankly its just not worth it.

and it doesn't matter if you live in an emission control area or not, keep the cats and keep SUV's on the road

sorry if this comes off political, and i swear i am not a tree hugger. just don't see the point if your car will go basically the same, performance wise, with or without the cats, and they will help out the enviroment if you have them.

And if you really think the cats are gonna hold you back, look into replacing them with a performance aftermarket, Jeg's carries some by dynomax that are pretty cheap and according to the write up, one of them will handle everything your engine can throw at it.

Leave the cats on. When I had my cat-back done I the cats flow tested, turns out there is less than 1 lb difference between entering and exiting flow.

i got the vehivlce and theer was none if they were on i would of left them on
but they were not there

It would still be a very good idea to put a cat on it. I used to have a Cherry Bomb Glasspack, the sound was very loud both in and out of the cabin, and it and the drone sound was terrible

what about runing one a glass pack and a flowmaster

My neighbor just bought a Ram for his son and it has glass packs and sounds HORRIBLE!!!!!!! Every time it goes by, I can't help but LAUGH at it because it sounds so STUPID. He thinks it sounds cool, but everyone on our street hates it.
Don't get glass packs.

ok thanks for the advice what about just runing one unverisal cat and then muflers

Ok, I have a related question here. I want to do the same thing, cat back with Delta 50's but I want to go up to a 2.5" pipe with a 3" outlet. Here's my question. Do I have the 2.25" - 2.5" adapter put on before or after the muffler? To me it would seem to make sense to put it on BEFORE the muffler, so the muffler flow is larger. BUt I'm just guessing here, can anyone give me some advice? Also where is the difference in 2 and 4 door systems? I find only 1 or 2 2 door systems, but ALOT of 4 door ones. Is there somewhere I could just cut 10" ( the diff. between 2 and 4 door length) out of a straight pipe? Or would I be better off just having a shop fab the pipes and buy the muffler?

the highway/interior noise comes from the delta technology, just check out their site, they have an explanation there of them... http://www.flowmastermufflers.com/cgi-bin/flowmaster/mufflers.html?id=2zsG2P8Y

yes can you please do this, I would really like to hear it..

Glasspacks are so 1990's

I remember in my old home town, guys would pour gas down the glasspacks before installing them, that way it'd burn all the fiberglass out right away. Then they would be seriously loud.

Sounds like a Flowmaster 50 is the way to go? I want some noise, but it's also my only vehicle, so I have to consider the family as well. I can't have it too loud.
