This listing is for the MPx Side Exit Exhaust WITHOUT Downpipe. This should only be purchased if you already have an MPx downpipe, or if you plan to do some custom fabrication. This exhaust system is not compatible with the factory downpipe and will not bolt up to any other downpipe. If you have anything other than the MPx downpipe, you'll need to have a local muffler shop do some cutting/welding to your downpipe to this exhaust. Don't want to go through that? NO problem, buy the side exit with downpipe package we have listed separately.

Introducing the MPx 3.0" Side Exit Exhaust System for the 03-05 Neon SRT-4. If you're looking for an aggressive sounding exhaust, you've found it!

Instead of using a rear exit exhaust, we've designed an exhaust that exits on the driver's side of the vehicle, just in front of the rear wheel. This provides the shortest path for the exhaust to exit, thereby increasing throttle response and power.

We've seen a lot of side exit exhausts in the past, but they always seemed poorly executed. They were angled down to clear the side skirts, or wobbled due to poor hangers. We made sure to eliminate those problems by doing the following:

  • The industry's first notched side exit exhaust gets the exhaust tip very close to the side skirt, but provides plenty of clearance so the exhaust won't contact your side rails or side skirts.
    This notch does NOT restrict power. We gained a solid 11 HP over the previous 2.5" exhaust our test car had on it!
  • We provide a hanger system, rubber hanger, and hardware to prevent the exhaust from rocking back and forth.

    I was wondering if this product would fit my AGP down pipe or if i would need to purchase the MPx down pipe. also if i chose not to purchase the MPx down pipe what fabrications would i need to make to my AGP down pipe to make this Side exit exhaust fit...

      We've never seen an AGP down pipe. We have seen a AGP O2 housing which bolts to the turbo though. Therefore, you should buy the complete kit with down pipe. It will then bolt on to the AGP O2 housing and complete the rest of your exhaust.

    exactly how loud is this exhaust? can you get a decibel reading from the cabin while cruising @ 70 or maybe at idle?

      We dont have a way to test decibel ratings. We have provided a video on youtube of this exhaust thats posted on this page. Please view the video below.

    What aside from the exhaust itself is included? Curious if it includes hangers and a new set of exhaust bolts? (Current downpipe bolts are rusted so I'd need 6 total)

      Probably not, but we have no way of knowing. We designed this to bolt up to the MPx downpipe. You can have a local muffler shop do the work to make this work with your needswings downpipe no problem though.
  • Joe
    Is the thing in the beginning of the exhaust a muffler, catalytic converter , or is it just a "test pipe"?

      Neither, its a resonator, or basically a small straight through muffler.
  • Kevin
    Can I purchase just the side exit section? I'm already invested in a custom ss down pipe and mid pipe with vbands.

    • Customer Service Rep

      Im sorry the way these are made by our fabricator, we make these in large batches, and do not have spare parts for them.

      You can buy the side exit without downpipe, but not without the mid section from us.

    Will I need to buy an mpx downpipe, or will my srs downpipe work with this exhaust system?

      This exhaust will only work with the MPx exhaust downpipe with three bolt flange.
