4-1 Exhaust Collectors 1.625” x 2.5” x 3.5” long w/ 7 degree Right-Sized” Transition Cones -2.50” x 3.0” x 4.1”.
4-1 Exhaust Collectors 1.625” x 2.5” x 5” long w/ 13 degree “Master” Transition Cones – you size the cone to your dimension! 3-1 Exhaust Collectors 1.75” x 2” x 4.25” long w/ 9 degree “Right Sized” Transition Cones – 2” x 2.50” x 3.2”.

Our custom exhaust merge collector kits include (2) Merge Collector bodies, (2) sets of Merge Bullet Vanes with assembly tool, and (2) Transition Cones - either “right-sized” or “master” transition cones.  Choose from over 360 different sizes, styles and materials - YOU choose!  But don’t let that intimidate you – we are here to help you narrow down the choices!

When you buy the exhaust merge collector kit not only do you save time by getting everything at once, but you also save an additional 10% off the already low price of the individual components! Exhaust merge collector kits are available in 3-1, 4-1, and 5-1 configurations, in Mild Steel and 304 Stainless Steel!

Compare our Exhaust Merge Collector Kit to the competition and you not only discover
how unique and easy they are to use, you will also find that you can purchase our exhaust header merger collector kit for less than HALF of what you would spend on an old-school merge. That’s like getting one for FREE!

In the exhaust merge collector kit you get to choose from 7-degree, 9-degree, and 13-degree transition cones, either “Right-Sized” or “Master” transition lengths.  The degree of taper affects the distribution of the power band. 

  • A 7-degree taper gives a wide band with more torque-y power at the bottom but may sacrifice some maximum horsepower on top.  These are great for street cars, road racing, shifter drag cars, or anything else where you want a broad, smooth power band.
  • A 13-degree taper gives a steeper, narrower, but higher band with most power coming on the top end.  Excellent for high revving engines that want maximum horsepower and can sacrifice it from down on the bottom to get it up top.  These are well suited to high HP drag cars, drifters, and dyno pulling.
  • A 9-degree taper tries to achieve a compromise between the two extremes.
  • Or choose from any other cone in our stock inventory of over 150 different sizes and tapers.

What’s the difference between a “Right-Sized Transition Cone” and a “Master Transition Cone”?  The “Right-Sized” transition cone matches the outlet of the collector and transitions you up to the next largest, common tubing diameter.  Whereas the “Master” transition cone gives you a large cone that allows you to fabricate whatever dimensions you may choose – giving you the ultimate in flexibility!
