it won't be very loud, I run without a cat and muffler on a 3" exhaust it sounds good bearly noticeable in cab. The turbocharger muffles most of the sound.

I have pretty much the same truck as you, I have the LD 2500 also a 1994, and I had quite a time making the 4" system not hit on the crossmember for the torsion bars. Your mileage may vary but be warned. If I was going to do it all over again, I would get a 3.5" system.

When I put a 3 1/2 on I saw how tight it is in places and wondered how a 4 would fit. Research shows negledigibe improvement between 3 1/2 to 4. 4 looks cool, and may be louder which on a sub will matter. Unless your dead set on a 4 save headaches and go 31/2.

My 4" system sat in the box in my garage for about a year. I found a shop that put it on for $80, a REAL bargain considering it would have taken me about half a day or more.

No cat, short glasspack.

It is louder than I thought it would be, but I don't think it would be an issue in a pickup. When I was towing my CC back from Kansas the noise at 65 was pretty intrusive. I am thinking of getting it under coated for rust protection & sound insulating.

Hiya Baddiesel,

I had to kinda oblong the pipe to make it fit with more than 1/8" gap. I got on the pipe with a rosebud, and when it was red gently squeezed it with a big pair of slip joint pliers. Just enough for some clearance. That was the only tight spot.

I put SS Diesel supply's 4" on my LD 2500 with no problems took me about an hour and half after the old pipe was off

When it was said that mileage may very.......did you mean get worse?Would this also occur on n/a 6.5s with lower than stock restriction exhaust systems
Thanks

No, I said YMMV on getting a 4" to fit past the torsion bar crossmember. I got better mileage. Sorry.. didn't mean to confuse the issue.

What is the best place to buy a 4" exhaust system?
I suppose the cheapest would be best... I can't imagine and real difference in quality of pipe.
How much did some of you guys pay for your 4" exhaust?

Sep - while I have not purchased one yet, (I am still on the steep part of the learning curve!) the least expensive (sounds better than cheapest!) I have found is a Pinnacle (Jardine) on Ebay. For your truck they have them on Ebay for $275 plus $45 i think it is for shipping. Do a search on ebay for "6.5 diesel exhaust" and it will come up. I think the next cheapest I saw was a SSDiesel for ...hmmm $350 I think? on ebay as well. No clue which one is better than the other!
