No prob.

 

I have the MBRP SI/DO that exit behind the rear tires. It's a good system. Very deep sounding. No drone in the cab at cruising speeds. There was some crackling after I would rev it, but it seemed to go away after a short break in period. The only problem I had was trying to get the tips to look level from the back. It's not impossible, but it is hard. I gave up and ended up removing the last section of piping on both sides and just put the tips on from there. So, the exhaust ends right on each side of the spare tire. I think it looks pretty cool having the "clean" look of no tips/pipes showing out the sides. However, you can see the tip from the side of the wheel wells. Not quite as deep sounding, but did gain a little in loudness. Better in my opinion and still have like zero drone.

 

Go MBRP. That's how I pay my bills now days fellas. Been a long time since I've been on this board but I am lurking again because I am eyeballin an ECOBOOST as my next ride.

 

I just installed my Magnapack in place of the muffler in my factory SISO...sounds amazing, no drone,nice and quiet when you want it to be, and a nice growl when you get on it...for $75 installed, I definitely recommend it!!

 

Cat-backs are boring, go for true duals.

 

ive been leaning towards an mbrp SISO system for a while now, i loved your 08, and i saw the thread with the sound clip in it. i even linked it in the last page. but when i go on youtube and watch videos of it, it does that popping, gargaling reving down thing my friends mustang does with no cats and straight through exhaust. im trying to avoid that. im trying to figure out what makes them do that. can you offer any insight? have you seen your siso kits make this noise most of the time? i guess its got something to do with the different cat setups on the 07ish and newers vs. the older 4 cat style, or if people are taking videos of them as soon as they install them and they sound different before getting broken in.

jesserohr if you can offer any insight as to whats going on id appreciate it. if you go back a page or so i show examples of it.

i was going to do true duals but from what i understand the popping cackaling sound is the nature of those systems.


anyone, what makes the maggie si/so kit so much more expensive? the magnaflow catback has a chambered muffler setup where the mbrp system has a straight through sort of muffler right? going by their measurements on the maggie site, the welded in universal maggie i have is smaller than the one in the catback?

 

If you're looking for a SI/SO system the 3" catback doesn't really have much gargle to it once the engine is up to operating temp. With the timing amounts changed drastically during the warmup cycle (when most people seem to video for whatever reason) everything is amplified.

We also have a turn down system for that truck, however it's pretty loud both inside and out. It's just a small catback system with a turn down prior to the axle.

 

I'll second the cold start thing. Until the trucks warmed up it does the gargling and poping, but once up to temp its deep and mellow.

 

perfect. i can deal with that. and rohr, you never get much drone right? i do remember seeing how you adjusted to get the tip to be out from underneath the bed, and that stopped some droning, so i know to try that.

not seeing many reasons to go with the maggie catback or why its so much more expensive.

and im sure i want a siso system.

should i spend the coin on the t304 system? or just go with 409?

 

Do you like your exhaust shiny or do you not mind the brown surface rust? 409 will develop surface rust (but wont rust holes through like aluminized) but t304 stainless will remain nice and beautiful. Another reason I like Borla and Corsa, aircraft grade t304 stainless.

 

i painted my stock catback with high temp black, i dont mind doing that. what do the borla and corsa kits go for?

maybe the magnaflow catback is t304? it just says 100 percent stainless on the site

 

I love my Corsa with dual 4'' chrome tips. Great fit and finish and excellent quality stainless. Plus it sounds awesome with no drone whatsoever.

 

That last video is mine, it only cackaled like that when the truck was in park.

 

does it do it when up to temperature?

if i get the AL system instead, the tip will discolor right? if im going to be painting the part under the truck with high temp paint and i can get away with the AL one i will, but i think the tips discolor or get surface rust, right?

 

I have a SISO 40 series flowmaster with 3 inch piping run from the cat back, sounds puuurrty mean if I do say so myself..
