So Ive been seeing a lot of people interested in what certain exhaust systems sound like so I decided to upload a few videos of my setup to give an idea. They were taken form my iphone so it does sound a bit different in person but it is just to give an idea.
I am running American Racing longtubes with catless midpipes to Magnaflow Competition Catback. Its not as raspy in person and sounds deeper.

Hope this helps out anyone looking to upgrade their systems!

Thanks for posting! did you notice any increase in horsepower and torque?

I never dyno'd my car before putting the full exhaust on, but to me it felt like a huge increase in hp & tq. After replacing the exhaust and adding the 93 canned tune from the DSP it seemed lke I was getting the proper airflow and would run through the gears very smoothly. I did jump on a dyno after the exhaust though and put out 408hp/405tq on a dymojet.

You probably should have dynotuned your car while on the dyno because I had ARH high flow catted 1 7/8" longtubes with their catback system and a K&N CAI as my only engine mods and got a lot more power out of mine. The tuner said there was more to be had, but it was pulling timing for whatever reason. The tuner suspected crappy gas, but I wasn't unhappy with the numbers anyway.

Porter cat-back

Is anyone familiar with Porter Mufflers? This is what a local muffler shop suggests for my RT. The Porter Muffler site has a video of an RT Challenger that has their mufflers and I think it sounds awesome, but am undecided until I hear more.

Impressive numbers! I never had my car professionally tuned, when I had my car dyno'd the shop i went to just adjusted off the Diablo to make sure my air to fuel was correct and all. I am getting a cam installed very soon and I'm gonna have Stu from Inertia tune my car while on the dyno.

Never heard of Porter. IMO I'd rather just go with a full catback system instead of changing the mufflers only. If you're gonna do an exhaust switch then you might as well go with a catback system.

That should add a LOT of power! I'd love to see your results after it's tuned.

 

[bcrawSRT8]

I'm hoping so! I'm also getting my throttle body ported by Fastman so I'm hoping that gives a few extra hp. I'll definitely post vids and numbers whenever it's done!

No, but I love the sound in that video.

Bcraw, do you not have emissions regulations where you live in TX?

We do. I just haven't taken my car to get inspected in the past 2 1/2 years so technically I'm running illegal lol. I do know a little shop down the street that'll more than likely pass me, just need to make the time for it.

I may not have said it correctly. I will be looking to change the mufflers and delete the resonator. Is not the same as a catback system?
