Re-Man Engine makes Exhaust sound different

[MarkRam2014]

Hello All, well it has been a long 3 months since my old engine got destroyed by P*.*Bys doing a Cam job which ultimately
ended up in me getting a new Re-man 5.7l Hemi Engine. One particular question I had with this new engine is my truck does
not sound exactly like my old engine when it ran good. The engine sounds real loud under the hood but not much exhaust sound
coming from the back that usually you are used to hearing, that sexy room sound.. It sounds like all engine under the hood,
It appears to drive good, however, the Gas mileage isn't as good I think, maybe 50 gallons less a tank, but I'm using 89 octane
now vice 87 with old engine. Any thoughts on this?

Re-man engines like Jaspers arent known to be quality rebuilds. so who knows why it sounds like **** now. Could be 100 things.

I hope this isnt your case and I really hope its not a Jasper motor because I agree 1000% with DILLIGAF . Jasper isn't known for their quality with any of their products. One of their long time sales rep's I used to deal with all the time when I worked at a local shop left them because of that reason. I've been burned a few times using their products. I would contact the shop that put the engine in and see what they recommend

Shoulda done a reman VS crate engine cost analysis. Yes sometimes brand new things have issues too but it's far less likely and in my opinion an everything new product is better than a possible beer o'clock rebuild coming from some sketchy places. Just my 2 bits. Hope it's something simple tho. Check all pulleys make sure it's not a bearing or something goin.
