I took both the resonator and the muffler and ran 3" pipe and a 3" bullet glasspack. The resonator is what bumps you from 3" to 4", so DON"T DESTROY OR LOSE IT!! The glasspack is a straight through design...took the sharp raspy note from the exhaust...sounds smooth, deep, and mellow...like a big truck...not like a powerstroke which (to me) sounds like a glorified V8 gasser. I too have taken out the silencer ring...turbo is louder...and I had 2 things happen. Mileage went up very slightly and my turbo spools up quicker...seems to have a little more oomph, but that could just be it sounding like it has more! My dad also took his out...his mileage went up a little too, but his spools the same...mine is a 215 HP auto, his is 225 HP 5-spd. steved

The resonator is used on the aftermarket exhaust systems to get you to the 4" diameter they sell. I got the glasspack from Summit Racing (they are online too). It was a Dynomax 3"x26" Bullet. I also got a length of 3" pipe from them (good pipe if you are just running a straight pipe). I took both the muffler and resonator off and ran the glasspack and a piece of 3" pipe to fill in that HUGE void. The 3" had to be welded to the existing tailpipe (at the former muffler/tailpipe joint). Only needed about 30" of pipe? to complete the gap. You could run a straightpipe, it's a matter of preference and if your planning on upgrading anyway, who cares...if you don't like it, you'll be changing anyway...right? If I remember right, the Pipe cost about $15 and the muffler was about $40. Add in the clamps and modifying the hanger (which also required welding) another $30...I remember having about $75 total wrapped up in it and I'm still running it. I'm sorta not willing to put $400 in an aftermarket exhaust, that's the reason I went my route. steved PS...I'm almost ALL stock except the exhaust, silencer ring, and modified airbox with a K&N filter.

There wasn't too much of a harsh sound difference under normal driving conditions. It sounds a bit beefier at the exhaust tip but overall it sounds the same. BUT, under acceleration, it definitely comes to life! Especially under hard acceleration! It sounds wicked! I was able to install the system without the resonator, but I had to install the muffler which is straight through. Unlike the V8 exhaust system makeover I noticed a considerable increase in horsepower with the cummins. I would definitely recommend upgrading to the 4" exhaust, not only for the performance but also for the EGTs. Your turbo will appreciate it.

There really is no advantage to stepping up to a 4" exhaust unless your at or above the 350 hp levels. you would be better served with a larger turbo exhaust housing for less monies if lower EGT's are what your looking for. If you remove the Cat you should hold on to it untill you are sure you can pass imissions since they can be very costly some guys just gut cat to get the sound but it is still in place for a visible inspection.

Aftermarket 4" systems replace from the turbo back, you will not need the factory resonator to get to 4". A stick of three inch, 3" saddle clamp, 3" band clamp, 3x3 coupler, and some hanger rod are what is required to get the exhaust flowing a little better. I have been running my 02 ETH/DEE straight piped since the second day I owned it....it sounds great.

Posts: 316 (08/28/02 16:10:37) Reply Quote More My Recent Posts	Most aftermarket exhaust systems I have looked into OFFER the 4" down pipe as an additional cost...most cheaper priced systems utilize the resonator to get to the 4" size to keep their prices CHEAP. Not trying to start anything, but...if you are looking to upgrade, KEEP YOUR RESONATOR...just in case. steved

Posts: 8 (12/07/02 11:11:03) Reply Quote More My Recent Posts	Remove this ad do not change your exhaust turbine to a larger one without changeing the exhaust. you will change the characteristics of the engies performance. Read the info on this site about performance stuff. changeing the turbo size affects it's boost and spool up plus when it makes power. if you raise boost you raise egt. ( read the wastegate info) Besides basic performance rules are simple: if you want more power add more fuel and let it breathe. Go for the 4 inch. Save the cat if you have a 12v. resonators were only on 24v's. If you live in a climate where you get salt in the winter buy a SS system if not buy an aluminazed one. The latter is not expensive.( around 300-500 bucks) remember: more air in and out of the engine, doesn't matter what fuel it burns means lower EGT and more effeciency.
