It is over $100, but when you figure in the pipes that are included and pre-bent, and the fact that this is going to last a long time, it's worth it.

I have a 2007 Nissan Titan LE crew cab, and the fit was very good.

(If it was 304 steel it would cost a lot more.)

Editorial Reviews

Jane's Review: Should I buy this product?

Jane's Review

Yes! I recommend this automotive replacement exhaust muffler based on manufacturer ratings. Let's go over the reasons why buying this automotive replacement exhaust muffler now is a good idea, and also things to consider before you decide on this item.

1. Manufacturer has very positive reviews on all their products!

The maker of a product is another factor you want to definitely consider before you buy anything. What if there is a piece missing or there is some defect in the product? With anything you buy online, there is a small chance of this happening. But don't worry too much, because Amazon has an amazing 30-day refund policy (Amazon❤️). Still, you want to make sure that the manufacturer or the seller has been helpful in resolving this kind of problem and/or has been helpful to its customers about general product inquiries. As you see in my manufacturer report below, Tenneco (Walker) has very positive reviews for their products. It's generally a good sign if the manufacturer has good reviews overall. If your purchase decision heavily involves how well they make their products and treat their customers, this is likely a safe bet.

2. This automotive replacement exhaust muffler has positive reviews on the internet

Some people have a great experience with a product, while some are unlucky and get a defected item and have to go through the whole process of returning them. Since people have different experiences about a product due to various reasons, don't read too much into one good or bad review. Reading multiple reviews with different ratings can help you picture how good/bad the product generally is.

This automotive replacement exhaust muffler has positivereviews on the internet, and based on current trends, it's likely that people will like this automotive replacement exhaust muffler more a week later. I summarized what fans and haters say about this product above in the good/ok/bad table, so don't forget to read those since they paint the whole picture! And of course, if you want to read more detailed reviews, many of them are on Amazon!See More Reviews on AmazonSee More Reviews on Amazon

3. Take a look at its price history

image/svg+xml Highest Price Lowest Price $131.09 $90.24

Price is one of the most important factors in making a purchase decision. I analyzed the price of this product in four parts: its recent price change, when it was most expensive/cheapest, its price volatility, and a price prediction I made, just in case you want to wait.

First off, let's talk about its recent price change. The price of this product has gone up, resulting in a 4.70% price increase.

Next, we need to look at its highest price and lowest price. Historically, the highest price point for this automotive replacement exhaust muffler was $131.09, and the lowest price point was $90.24. The current price isn't close to either the highest or the lowest price point, so it's a fairly reasonable time to make this purchase.

What about its availability and price volatility? This is another aspect we have to dig into before buying something. I haven't seen this product being unavailable since I started reviewing this product. So as far as the availability goes, this product is solid. If you plan to make a repeat purchase of this kind of item, this is your product! In addition, I've seen a small amount of price movement with this product. From what I've seen, the price is likely to move up or down by an average of 2.03% at a time.

Considering all this, will the price go up or down in a week? Based on past price points, I expect the price to be $113.81 a week from now. It might be best to wait for a future price drop, but if this product checks all the boxes for you, don't wait to optimize for small gain.

4. Make sure Walker is a brand you can trust

Walker doesn't attract too many people on Amazon among other automotive replacement exhaust muffler brands. I couldn't find any YouTube videos, Reddit posts, or news articles that directly mention this product, but this can be just me not looking hard enough. Will update this when I have more info!

One thing to be careful about here is that I'm not verifying if this product's maker is a household name or not. This section is more focused on whether this is proven enough by its consumers, whether people actually love this product.

5. There are other options you might want to check out

image/svg+xml Walker Other similar brands: Dynomax Thrush DEWHEL iSaddle

I found 5 brands that have similar products like this one: Dynomax, the same brand as this product, Thrush, DEWHEL, and iSaddle. 'If you're looking for a cheaper alternative, you might want to look at a similar product from DEWHEL. If you're looking for a automotive replacement exhaust muffler with best reviews, a product from Dynomax gets the best score on the internet. If your primary concern is whether the product is popular and well known, a similar product from DEWHEL I linked below is a better option. I linked all the similar products in the similar products section so please check them out! Or you can check other similar products on Amazon, too.
