OAL; Unnotched; T-304 Stainless Steel; Review: Nice Sound on 2005 Tacoma Xrunner - I bought this muffler (Borla 40357) for my 2005 Toyota Tacoma Xrunner. It is 2.25' offset/center on the inlet/outlet. When I first got it out of the box, I was very surprised how heavy it was (probably 7-9 pounds). It's appears to be very well constructed and of very high quality. I ordered the 2.25' version after reading that Toyota uses metric size tubing and the 05-08 Tacomas are closer to the 2.25' diameter, while the 09+ models are closer to a 2.5' diameter. I had it installed at a local muffler shop and had it installed. He said an offset/offset inlet outlet would have fit better, but he made it work. Upon initial startup, (the rest of my exhaust is completely stock) I couldn't tell a lot of difference between the 22 inch long chambered stock muffler and this 14 inch long straight through muffler. I've put about 500 miles on it in the first 3 weeks of having it. There is some noticeable resonance in the cabin from 2300rpms to about 2700rpms when casually accelerating. When you're coasting or maintaining speed, it is nearly identical in volume to the stock muffler. On the highway, I notice a little bit of drone/resonance, but it's not bad. My truck isn't very quiet in the cab to begin with, and I've ordered some sound deadening mat to counter the road noise and small amount of resonance. In regards to sound , this muffler sounds great. It's very deep and rich, mellow under mild acceleration but really wakes up when you get on it. There is no raspy sound to it and no loud popping, just a very mellow gurgle when decelerating. In regards to performance, it feels like it has a little more low end torque, and when decelerating, I've noticed the back pressure is greatly reduced (probably half of what it was). Overall I'm very happy with my purchase and would recommend it to anyone wanting something mild, but noticeable to replace their stock muffler. Here's a link to a video of what it sounds like on a stock Tacoma. I think mine's a little quieter because it's 2.25' vs his 2.5' version (40352). https://www.youtube.com/watch?v=XU-IlLA5i_w Review: Sounds good - Sounds good on a Jeep yj 4.0 ## Features - T-304 Stainless Steel - Weld On Installation - All Welded Construction - Made In USA - Un-Notched necks are designed for weld in installation. If clamping, use 3" wide band clamps 18003. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0060EI8SQ | | Best Sellers Rank | #84,825 in Automotive ( See Top 100 in Automotive ) #12 in Automotive Performance Exhaust Mufflers #58 in Automotive Replacement Exhaust Mufflers | | Brand | Borla | | Brand Name | Borla | | Compatible with Vehicle Type | Truck | | Configuration | Offset/Center | | Customer Reviews | 4.8 out of 5 stars 65 Reviews | | Global Trade Identification Number | 00808422403573 | | Included Components | Muffler | | Inlet Connection Size | 2.25 Inches | | Item Type Name | Muffler | | Manufacturer | BORLA | | Manufacturer Part Number | 40357 | | Manufacturer Warranty Description | Manufacturer warranty | | Material | Stainless Steel | | Material Type | Stainless Steel | | Model Number | 40357 | | OEM Equivalent Part Number | BDLS40357 | | Shape | Oval | | UPC | 808422403573 | | Vehicle Service Type | Truck | ## Product Details - **Brand:** Borla - **Configuration:** Offset/Center - **Material:** Stainless Steel - **Shape:** Oval - **Vehicle Service Type:** Truck ## Images ![BORLA 40357 ProXS Universal Performance Muffler 2.25" Offset Inlet / 2.25" Center Outlet 4" x 9.5" Oval x 14" Long body 19" Overall Length Reversible Design T-304 Stainless Steel - Image 1](https://m.media-amazon.com/images/I/51vXeJgAR1L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice Sound on 2005 Tacoma Xrunner *by M***R on December 25, 2015* I bought this muffler (Borla 40357) for my 2005 Toyota Tacoma Xrunner.
