Ideas on exhaust Rasp

The Dynomax race mini mufflers work great at eliminating rasp without lowering the volume or aggressiveness of your existing system. They're only 6 inches in length so they're very easy to add to an existing exhaust setup. You can also find a pair of them for $40.

The Challenger/Charger guys have been using them for years. That's where I got to idea to use them on my Mustang for eliminating rasp in the upper rpms.

I got a couple of those, was going to have them installed in place of fake canisters/cats that came with the TSP Longtubes. Decided to just use the Tru X. Wish I would have just gotten the muffler and had an exhaust shop make extensions. Cheaper than ordering the CJPP part. Just no good weather/time to install this week in Florida. I paid $36 shipped for the min bullets via amazon prime.

Had the 3" in/out Magnaflow Resonated X-pipe installed today. Cost $125.00 for the job and the X was just over $100.00. All the drone and rasp are gone and the loudness is much less. Honestly I can't believe how much this calmed the exhaust down. Might even be a little quiet for my taste but sticking with it. The flow is great and the exhaust isn't obnoxious, awesome. It's actually fun to drive again!

@MagnaFlow I too got the Tru X on today that I purchased from CJPP. Its a little shorter than the Steeda X pipe was so the shop had to add some piping. No drone at all in the cabin, car is smooth. Only drawback is before I could tell how fast I was going by the loudness of the car. Not anymore, was doing some triple digits on the highway before realizing it.

Was $135.00 to install. Shop added some brackets that attached to the muffler to keep it from drooping the future. Also fixed the hanger on my axle back to center the muffler. I am pleased!

[MENTION=34639]Shane361[/MENTION] do you have any pics of the install? I am looking to go this route on my car and want to make sure my idea will work. I've got a 3" cat back and I am going be adding a Mak Cat delete.

The 2.5 to 3.0 stuff is getting a little maddening, combined with the fact that I'll need to get my stock cats back on for emissions.

Thinking of getting the same X as you and the 3" cat delete, then just throwing a 2.5" to 3" adapters on my cats.

I don't sorry, have not been under that car since it was installed. It was custom work so any good shop should be able to weld it into place.

[MENTION=13048]MagnaFlow[/MENTION] I noticed the TruX comes in a 2.5 in 3.0 out. Do you think there is a big difference in flow between that and 3.0 in/out?

I have a 3" cat back with a factory connect. I am taking the H out and putting in one of your resonators and a Mak cat delete. I can get the Cat delete in 3" and go 3" all the way but that's going to make it hard to get my stock cats back on when needed.

I had my Tru X installed last week. If did it over again I would just buy the Magnaflow Muffler and have the additional piping put in. The muffler shop installer told me to do that. I paid $245.00 for the Tru X when I could have just gotten the muffler for $127.00.

Glad to hear that, as its the route I have to take.

You still happy with it? Hoping it quiets down the car enough to make removing the cats a net zero sound increase.

beyond happy. it has made the car fun to drive again. It sounds stock on the inside but on outside a nice rumble. No rasp at all just pure booming exhaust and no noticeable loss of power.
