Product Details

The Pypes Performance Exhaust SGF11S Street Pro is a complete crossmember-back exhaust system engineered to deliver enhanced performance, improved fuel economy, and an aggressive yet refined exhaust tone. This header-back dual exhaust system features mandrel-bent 16-gauge 409 stainless steel tubing with 2.5-inch intermediate and tailpipes, ensuring maximum exhaust flow and significant horsepower gains while resisting corrosion for long-term durability.

Key Features:

  • Complete kit includes X-pipe crossover, two Street Pro chambered mufflers, tailpipes, stainless steel hangers, clamps, and installation instructions
  • Street Pro mufflers deliver a rich, throaty tone at idle that transforms into smooth, authoritative sound under acceleration
  • Single inlet/single outlet chambered mufflers with no internal filler maintain consistent sound quality for the life of the system
  • Mandrel-bent construction maximizes exhaust gas flow compared to factory crush-bent systems
  • Dual split rear exit configuration with 2.5-inch diameter tailpipes
  • Slip-fit connections facilitate straightforward installation (some cutting may be required)
  • Recommended for stock to medium-modified V8 engines where aggressive sound is appreciated
  • Exhaust tips sold separately

The SGF11S system is precision-matched to outperform and outlast factory exhaust systems. The included X-pipe design balances exhaust pulses between banks for improved scavenging and a more refined exhaust note compared to traditional H-pipe or non-crossover configurations. Stainless steel construction throughout ensures years of reliable service backed by Pypes' limited lifetime warranty.

Great so far

Very satisfied.

Fast shipping and the product met all of my expectations.

You had what I needed.

Excellent company to do business with Thank You

Hello, Good price, almost as low as Amazon, but Amazon shipped me a broken headlight switch :( twice! :( So for my order# 602429, please bubble wrap it really, really, really well please, and then I will be ordering more parts from Autoplicity. Thank you! Jeff

super !!

This is my second time ordering from Autoplicity and both times they had the lowest price on the items I was looking for (brake pads and CAI filter). Fast shipping, my filter was at my door two days later. Overall very satified.

Lowest prices I found on the net and great customer service! Fast shipping too!

Was for head gaskets. They used to come 2 to a pack--now same price and there is only one in the pack (1135g) Mr. Gasket. Knowing this, I wouldn't have ordered.

Great service when calling in to ask technical questions regarding the proper part for my 2006 Winnebago. They shipped quickly and processed the transaction promptly.<br><br>Thanks <br>Jason

Great products, and pricing

I ordered a universal Hurst Pistol Grip "shift knob" for my '12 Mustang GT. It squeezed to a perfect fit right where I need to grip it. It improved shift time and accuracy greatly and feels and looks great! Autoplicity had the best price on the web and I got this in 3 business days. I recommend this product.

Order was fast, had the products I wanted in stock, and vehry pleased. Thank you 5 star service.
