Hey guys, My exhaust from the catylist back on my '90 4.0 is junk. Any suggestions on what system I should get? Also is there a cheap aftermarket header with a better flow rating?
i run rustys kit too. i found after i installed it that i could have gone to the local exhaust shop and gotten the same flowmaster and everything that comes with his cat back plus installation for the same price. ive been happy with mine though so i dont really care. btw the flowmaster makes a nice skid plate for itself, not sure if other mufflers could stand the abuse that a flowmaster does.
I have designed a new wheeler muffler that we will be welding up to test this next month it willl be rectangular with same style baffles as flowmaster has. shorter. with expanded end on input side and crimped outlet side, you should be able to jack the jeep up from this one
www.jegs.com has dynomax cat backs for 85$, and if you time it right, you can find a 25$ coupon in hotrod mags (4wheeler too?) and it makes it 60$, damn good deal if you ask me. Good quality too.
So flowmaster is that much better huh? Well I have in sitting in my garage I had on my old Bronco so it's slightly used. Only thing is it's 2.5" pipes.... So if I go to get adapters for it, and cut my stock muffler off at the rear, what size Adapters would I need to match the factory pipes? 2.25 OD?
SO better to put on a flowmaster that has some miles on it or a new cherry bomb?
I just put on a flowtech afterburner. They are built like a tank (fully wellded heavy guage steel) and are 39.95 from summit racing.
Got a walker tailpipe at the parts store for $20, a straight piece of pipe flared to 2.25ID on one end for $5, two clamps $5, for a grand total of $70. That is less than a flowmaster by itself costs.
The flowtech sounds pretty much the same as a flowmaster but has no resonance problems at all.
hmm... well do you have a headder and a race cat? Mine is low toned... maybe its the MSD.
I donno... I never ment for ya to end up with a rice burner sound...
I just got a Ravin put on at Midas yesterday... cat back.. right at 2 bills... The reason I like Midas is.. well.. they're cheap and they use aluminumized pipe.. (i don't want to pay for stainless)....
On my previous TJ.. it sounded pretty darn good.... on the XJ... you can't even really hear it... the Swampers kinda drown it out... but it does have more spunk so it was worth it...
I don't know.. but six cylinders just never sound sexy... Wheeled with a WJ with Flowmasters and DAMN... I got out to spot him while struggling on a log.... I heard a Vette but was lookin at a Jeep... It was awesome!
