It's loud which I expected but I think it's making the truck bog from 1st to 2nd.. Guy at the muffler shop more or less talked me in to dumping it at the rearend so I know it was going to be loud but something just doesn't seem right.. Almost like its completely affected the way it runs cause it's sorta sluggish as well.. Do you guys think that adding dual tips out the rear would help with anything or should I just swap it out with a borla?

Don't let ANYONE, talk you into ANYTHING!!!!

Yeah, that pretty much amounts to he didn't want to bend the pipes and do the work to do it right. Definitely need to get that loud out from under the truck for all to enjoy :naughty:

As for the sluggishness, did you do anything else to the exhaust? Kind of odd for a cat-back to affect the truck that much.....People have reported lost torque with true duals off longtubes.....this doesn't seem like it should have lost anything.....

Agreed. Now that sound is just reverberating of the ground and its gonna be hella noisy in the truck.

As far as power loss, I too am a bit surprised it's as bad as you describe, though you won't believe how many guys run open headers at the track because it's gotta make more power that way, only to find later on that they consistently get better ET's with some sort of exhaust. Less isn't always more when it comes to back pressure. Scavenging and all sorts of other variables contribute to an exhaust system helping or hurting performance.

Regardless, I'd lose those little turn downs for pipes out the back lickety split if it were me, but that's just my opinion and that plus a buck fiddy will get ya a cup of coffee... [emoji12]

To that end, there was a time I slapped a temporary exhaust on my ~550 horse Buick just to get to an event on time. It was headers, straight into some bullets, and then turndowns. Sounded like a damn nascar. Everybody thought it was awesome except me, as I was the poor shmuck inside the car getting my fillings rattled out of my head. I went to a full magnaflow system, and although I have no ETA to back it up, it was a noticeable power increase over the shorty exhaust. Didn't sound as vicious, but definitely pulled harder.

If they are open tomorrow I'll be getting the pipes ran out the back with my DC resonated tips like I was going to do.. I wonder if that will help me much or if I should try and stuff some resonators in there before the tips.. I like loud just not in the cab where you can't hear **** and it vibrates everything.. Oh and the truck is other wise stock other than the muffler..

Worth a try to see if it helps. It will definitely help with the cab noise although you'll lose your "free" back massager :naughty: It's not hard to put the resonators in later if you want :happy107:

The "ass dyno" doesn't lie. No joke, I have the same feeling in regards to my magnaflow 14". I feel a slight loss in low end power. Serious. Felt it immediately! Only mod that I have buyer remorse for.

Try the Borla. Let me know how is goes please. Cuz I am considering.

If it was me I would be a little pissed about the workmanship on those turn downs. That tells me right there he didn't want to take the time to do a proper install.

Well it looks like the spintech is coming off and a Borla proXS will be going on in its place... Oh and I will be running the pipes to the bumper with resonated tips.. That's got to quiet it down enough and get rid of the drone and hopefully the weird flubbing sound when it shifts sometimes..

I didn't have any drone at all when I had that same Borla setup.

It was a while ago so I don't remember exactly. But I think I already had the MDS disabled with my tuner when I got the Borla.
