Back when the Caliber SRT-4 came out, we were a little disappointed that it came from the factory with a single exit muffler/tip when the Neon SRT-4, its predecessor had a dual exit exhaust.

So, we set about working on a dual exit exhaust for the 2008-2009 Caliber SRT-4. When we were working under the car we found that the factory B pipe, which went from the downpipe to the rear muffler was already 3 inch, and fairly straight. There wasn't much room for improvement, so instead of designing a whole catback we designed a rear muffler section, which saves cost.

Design
We started the design with a T304 stainless steel straight through, turbo style muffler which has very high temp fiberglass packing to quieten down the exhaust tone, and eliminate any raspiness. This style of muffler allows for a quieter tone than a single exit muffler because the exhaust gases spend more time inside the muffler, therefore reducing the sound more. The rest of the piping and tips are also T304 stainless steel which is very durable, strong and good looking.

Installation
Installation is straightforward, two factory hangers are used, and we attach on another hanger onto the frame (no drilling required!) to make sure the exhaust is solid. You simply cut the factory piping (we provide a template!) and then slip the factory piping over this muffler. We provide a clamp, but we highly recommend you weld the exhaust to make it super solid and leak proof. We also provide instructions and a template showing where to cut the rear valance to make room for the new tip on the drivers side. Don't worry, its easy!

Sound
Sound quality is nice, it has a deep tone, and is not obnoxiously loud. You can drive on the highway without going crazy from drone! You'll enjoy the sporty tone and great looks this exhaust will give your Caliber SRT4!

• We use a hand rolled muffler for a cleaner look with no pinch seams.
• This second revision uses a larger muffler for a smoother sound with less raspiness.
• The new muffler design uses flanges on the tips to allow for smaller packaging, saving nearly $70 in shipping costs as the old box was massive!
• Now using a 3 inch inlet and two 2.5 piping to keep the velocity high out of the exhaust vs 3 inch in and dual 3 inch pipes out.
