Does your tailpipe go all the way out the back under the bumper ?

No it comes out the side, more of an angle than stock though.

Well, I gotta figure out how I’m gonna do it first, but right now I’m thinking putting the magnaflow in place of the Corsa and then driving it and seeing what it sounds like. I’m going to keep the Corsa muffler of course just in case I want it back on there.

That is what I would do

If you care to make the tailpipe longer, that will help.

I think you'd be happy with the vibrant resonator and that muffler. Get rid of the second muffler..

That would be pretty comparable to my previous set up before I added the second resonator (I laugh every time I say that.. it's a wonky solution.)
I was happy with the sound I had with just the one resonator, no crazy rasp. I wanted more because when towing I'm spending long periods of time at 2500-3000rpm and it was just too much sound to have constantly.

The muffler you're getting should be quieter than the one that I have with my SPD catback.

BTW, these are the clamps I've been using. Much nicer than anything else I've tried: Summit Racing SUM-681300 Summit Racing™ Lap Joint Band Clamps | Summit Racing

I put some copper RTV on the joint then slide these on. No leaks since I started doing that, and they don't deform the pipes.

We’ll see how things go. Thanks for the suggestion! I just ordered 4 of them right now.

It will help with no back pressure?

It will help with the sound.

 

[boostkingMatt]

It will help with the sound.

Yeah, but I’d only be extending it by maybe 8 inches if I did that.

8” impresses a lot of people!

Hmm, well I kinda like how it is right now, the look of it I mean.

 

[Boatwaco]

I prefer a side exit exhaust too.

I prefer a side exit exhaust too.

The raptor is straight out the back, and dual even and I’ve heard a raptor exhaust and it’s almost raspy.

 

[boostkingMatt]

Time for the install! Thanks @bentruby for the clamp suggestion, and we will see how this magnaflow sounds.

 

[boostkingMatt]

So here’s what happened, I can’t remove the Corsa muffler because it has the hanger welded onto it. So if I removed it I’d have no hanger in the middle. So I put the magnaflow where the Flowmaster was. I haven’t driven it yet, I’m about to, but it seems like there’s still some rasp. I think what I’m gonna have to do is get a resonator and put the magnaflow where the Corsa is and the resonator right before the magnaflow.

 

[boostkingMatt]

The exhaust is actually pretty nice. If there is any rasp I can’t hear it. It sounds very good at WOT, at least for a second…..

….and that’s where the tune comes in, so the truck is on Torrie’s 15th or 16th revision already and I put the foot to the floor, she spooled up and sounded good, till about 5500rpm then all boost dropped out and went into limp mode. Got an overboost code. I looked at the log and right when I got the code, the wastegate closed completely. It was around 32% for the beginning of the pull, throwing down 16-17 psi and then it just dropped to fully closed and went all the way up to 19+ psi.

So I cleared the code and tried it again, same thing. Something ain’t right…

 

[boostkingMatt]

All is good all is good. Boost was headed out of bounds and so it hit the limit. It’s adjusted now and it pulls HARD. Spiking to 17psi initially and then falling to 9-10 at redline, it’s feeling like a monster. Hardest it’s pulled so far. It put a big grin on my face.

Raced a cummins diesel yesterday with dual stacks. He was in front of me in the right lane and I was in the left. I gave it some sauce and he was already giving it some sauce. He saw me in the mirror and gave it all the sauce. He was rolling coal. I pulled right past him with no mercy at all.
I chuckled to myself and waved at the guy and he waved back. Funniest part of the whole thing to me was that I was only on 10-11 psi and about 32 lb/min.

 

[Arkansas Eco]

Good job !

 

[bentruby]

So it sounds good now?! Videos?

Resonators typically go before the muffler, they recommend them being under the passenger cabin. Do what you need to do though!
