How to Straight Pipe a jeep wrangler

How to straight pipe a jeep wrangler

I live in a beautiful county, where emissions testing is not required. As a result, people commonly straight pipe their various rigs here. Furthermore, rust is merely a rumor in this beautiful country’s coastal parts, and it does not exist in this clean setting. Should I straight pipe my 07 JK, as the title of this topic suggests? I’ve heard that removing the cats and turning off the 02 sensors can cause major tuning issues and engine performance degradation. That’s not something I’d like. I suppose I should speak with one of the shops here that specializes in straight pipe vehicles, but I wanted to see if anyone in this community could offer some sound advice, cautionary tales, or general exhaust knowledge. I’m trying to avoid being too loud. But I do want a meaty grumble (yeah, I know I should install anything greater than the 3.8) and, most importantly, the increased power and efficiency that letting an engine to breathe provides.

Pipework with no bends

Straight pipe reduces backpressure in the exhaust system, which might impair performance. From what I’ve heard, it could also burn out your valves. I can’t comment for performance on a straight six, but owing to a catastrophic muffler failure, I once straight piped a 4 banger Trooper. It sounded a little like a want tube NASCAR truck, louder and meatier than it did with the muffler. When the battered old 86 Trooper pulled into a parking area, it drew a lot of attention. It did have an effect on performance; it offered me more access to higher RPMs and overall speed (I could finally max the speedo out at 85 without her thinking the engine was about to blow), but torque was reduced. I dropped into third gear to climb hills on the highway, where I had previously been in fourth. However, this was with a 2.3L four-cylinder engine.

As previously stated, the JK’s require back-pressure in the exhaust system, hence doing so will result in power loss. Unfortunately, many modern engines fall into this category. They’re all built to be ’emissions friendly,’ which means they’re made to work with the cats and mufflers installed; without them, many of them will lose power. Without cats and 02 sensors, the ECM uses the readings to identify if the engine is running rich or lean, and adjusts the fuel-air mixture accordingly. On a related point, I’ve heard that switching to a true dual exhaust on the JKs reduces power due to the loss of back pressure.

  • Straightening a pipe

Find the lengthy section of muffler pipe under the driver’s-side seat under the vehicle (see photo below). You’ll be removing a part of the exhaust pipe from this location.

Place your new muffler in that spot to determine whether it will fit without snagging on any metal. Check that the muffler pipe outputs match the Jeep’s exhaust pipework. Left side to left side outputs should be used.You’ve done it correctly if there’s enough room to place the new muffler and nothing is hitting it. The pipe can now be measured and cut.

  • Cut twice after measuring three times

You’ll need to double-check your measurements in this scenario, and then you’ll have to cut the pipe twice! Alternatively, there are two options.When measuring, make sure the pipe is long enough to fit into the muffler piping (see photos below).With a permanent marker, indicate the area where you want to cut. Check your measurements once more to be sure.Cut the pipe with a circular saw. The muffler should then be fitted to the pipes for a trial run.

  • Select Installation Parts of Superior Quality

Without the use of clamps or welding, the muffler should stay in place once installed. If it doesn’t, you’ve probably cut too much tubing and will have to weld it in.Invest in muffler clamps that are rust-resistant and evenly bolted down (see the photos below). This will provide an uniform clamp across the whole surface of the connector.Your new muffler is now mounted by tightening the clamps on both sides. However, we are not yet finished.

By yourself a straight pipe

Building your own system is less expensive, allows you to develop a performance-based exhaust, and improves system flow. Although constructing a straight pipe exhaust is not technically difficult, it does necessitate some mechanical understanding and the appropriate tools.

How much does it cost to straight pipe a Jeep Wrangler?

Replacement Cost Estimate for Jeep Wrangler Exhaust Pipe Labor costs are expected to range from $81 to $103, with parts costing $591. The number and age of Jeep Wranglers on the road are used to determine this range. Use our Fair Price Estimator to get a more precise figure based on your Jeep and region.

Is it bad to straight pipe your Jeep?

For a street vehicle, a race car exhaust system is a horrible addition. Exhaust gas velocity can be increased by using a straight pipe, for example. This will likely impair engine performance below 2,000 or 2,500 RPM, making your car slower to accelerate from a stoplight.

Does straight pipe hurt your engine?

Straight pipes, for example, can speed up the flow of exhaust gas. This will lower engine performance to below 2,000 or 2,500 RPM, making it more difficult to accelerate from a stoplight. A popular car performance modification is an improved exhaust system.

How much does it cost to run a straight pipe?

On average, straight pipe installation for your car would set you back between $1000 and $1500.

How to straight pipe a 2011 jeep wrangler?

a device placed in front of the muffler. It has an open valve that allows the exhaust to escape, as well as a valve that blocks the muffler port, as far as I can tell.
