What made you choose this particular product?
Got it as a gift to finish off my 2.5 inch custom catback exhaust.
Is this your first time buying from this brand? Did you consider other brands?
Yes it is my first time using this brand.
Was it easy to install? Any installation tips that will help others?
I installed it with some friends. A welder is very helpful since hangers are not included with the muffler. I reused the old hangers off of the stock exhaust and it works pretty well.
Once you've had a chance to use the product, did it meet your expectations?
Completely blew my mind how good it made my car sound, 100% worth it, especially for only $32. Car is quiet at low rpm, even with resonator deleted, loud, but sounds great at high rpms. Don't notice any drone at all.
Any additional comments?
Great if you want to get some more sound out of your car without breaking the bank or making it super loud.

What were you trying to accomplish by adding this product?

Had the exhaust professionally installed
Once you’ve had a chance to use the product, did it meet your expectations?
It meet my expectations and more, it gave me the loudness I was looking for plus a amazing sounding rumble
Any additional comments?
When doing exhaust I would always have it professionally welded

About FlowTech

Flowtech Performance Exhaust was founded in 1994, by exhaust market expert Gary Biggs, with the mission of delivering high quality performance exhaust at a great value. The mission was successful and in less than two decades Flowtech became the leader in value priced exhaust systems. Flowtech cornered its place in the market with aggressive and memorable product names such as Raptor™, Terminator™, Afterburner™ and Warlock™. Flowtech even revived some names from back in the day like Purple Hornies™. Flowtech made its mark with simple yet effective improvements like slotted port flanges giving added wiggle room during header installation. They dimpled their tubes at the port to make more room for the header bolts and they parallel ground their flanges to assure a tight seal. Flowtech innovations include their unique Afterburner headers which separated the odd firing cylinders with a velocity tube to improve scavenging. Their patented Warlock bypass muffler won the SEMA best new product award for its revolutionary open or closed design in 1996. When Flowtech became part of Holley Performance Products in 1999, the company continued to focus on value, with an emphasis on late model cars and trucks. Headers and exhaust systems were developed for Mustangs, Camaros, and all types of full size trucks - including diesels. The same innovation continues today with the addition of universal X-pipe kits and X-pipe kits with built in cut-outs. Continuous product updates and improvements to manufacturing processes will keep Flowtech the leader in value priced exhaust systems. We hope you enjoy your Flowtech product as much as we enjoy building it!
