XForce 4" to 3" Turbo Downpipe & High-Flow Cat Kit - Audi RS3 8V & TT RS FV - ESRS317KITB
Unlock the full potential of your 2.5L TFSI engine with the XForce Turbo Downpipe kit for the Audi RS3 (8V) and TT RS (FV). This premium upgrade is designed to maximize exhaust flow by replacing the highly restrictive factory component. Crafted from high-quality 304 stainless steel, the system features a massive 4" inlet that transitions smoothly into 3" mandrel-bent tubing. By deleting the secondary catalytic converters and utilizing a 200-cell high-flow metallic race cat, this kit significantly reduces backpressure, resulting in improved throttle response, increased horsepower, and a much more aggressive, visceral exhaust note.

Tax Hero!
Format: Paperback
I was scraping pennies for supplies in my small coffee shop located in the lowest level of an office building in Cleveland, OH. "Bookkeeping" consisted of a greasy shoe box nestled in the corner near the window. Tax wasn't an immediate concern because I barely had enough to pay rent. Several years passed. The box became larger and greasier. A friendly customer asked whom I would suggest for tax filing. I said, "When you find someone, let me know." When he visited again, he gave me a business card. By now, the box was bulging. I would have been embarrassed to approach a total stranger, but my customer was kind and I imagined his connection being the same. I got a cleaner, newer box and stuffed receipts corner to corner for facing the music.
What does my story have to do with Doug's book?
That scary first filing with the kindest person I've met in my long entrepreneurial career taught me a valuable lesson.
By the time the accountant stopped laughing at my "bookkeeping", he said, "I'm going to help you this year because you're trying to be a serious business person, but don't ever come to my office again with a shoebox. You have to keep records even if its time consuming. You also need to be incorporated, I'll help."
Lucky you! You have a hero.....Doug Collins.

Game Changing Information!
I bought this book months ago and like many others, it found its way to a pile of books I like to call "I'll read them eventually". Yesterday was eventually. A simple read, finished it in one sitting and came away with mountains of info that will save me thousands and even get me money back on previous years taxes. Great info on tax investing strategies as well, well worth the purchase price, and I can't wait to write it off!!

Great advice & tips
Format: Kindle
This book is helpful to new business owners with little to no experience with business tax preparation. I had about 5 pages that was helpful to me because I have had my small business for 8 years and familiar with some of the home based business write offs but there was some useful information that. Are it worth the read.
