Overview:

Dinan engineers designed the BMW 330i/430i exhaust to improve exhaust flow by reducing back pressure, resulting in increased power output and a great sporty sound that is civilized when you want it to be, and pleasantly aggressive under hard acceleration. Like all Dinan exhausts our 330i/430i Free Flow Axle-Back Exhaust is engineered to reduce low-RPM drone so the cabin of the vehicle is still intimate and not drowned in an excessively loud tone. The system is built with ease in mind and utilizes a simple bolt-on installation with included mounting hardware. It is made from 100% 16 gauge 304 stainless steel and will resist corrosion for years to come. The design features twin 3" ceramic black or polished and laser engraved exhaust tips for a tasteful, high-performance look that yields a maximum performance gain of 4 horsepower and 3 ft-lbs of torque. The factory computer-controlled exhaust valve is eliminated.

Features:

  • More Power: + 4 HP @ 6600 RPM, + 3 LB-FT @ 6600 RPM
  • Drone abatement technologies used to reduce cabin resonance
  • Enjoyably louder, sportier sound
  • Twin 76mm (3") laser engraved, polished or ceramic black exhaust tips
  • 100% 304 stainless steel construction
  • Uses the factory brackets and hangers for a factory-like fitment

read the fine print
Size: X-Large, Color: Black
I really need to learn to read the small print. That pocket line on the chest turned out to be a fake pocket and the actual; zipper on the sleeve is also a fake pocket; my bad but in my defense I'd never dreamed that anyone would put either on a shirt. Also my search term was men's "cotton shirt w/ pocket shirt" and it brought up this polyester wonder. But at least it fits well and seems well made.

High‑style look that feels way more expensive than it is.
Size: X-Large, Color: Orange
Okay, let’s talk about this shirt because I was not expecting to love it as much as I do. The Men’s Long Sleeve Polo Shirt with the quarter‑zip is giving premium designer energy without the designer price tag. From the moment I put it on, the fit was chef’s kiss—slim, clean, and athletic without feeling tight. The fabric has that smooth, high‑end feel you usually only get from brands that make your wallet cry. But here? You’re getting elevated style at a totally reasonable price.

Magnificent fabric
Color: Pink, Size: Medium, Color: Pink, Size: Medium
A beautiful sweater—exactly like the one in the photo. The fabric is stretchy and of very good quality; it is perfect for a casual occasion where you also want to look practical. It pairs very well with shorts.

Great Sweater
Color: Black, Size: 3X-Large
My son wore this to an event he got so many compliments on it. The quality of the fabric and the design makes it look so much more expensive.
