Dynatech 780-03519 Hi-Velocity Merge Collectors

Dynatech 780-03519 2-3/8in x 4-1/2in Merge Collector

Dynatech merge collectors are a popular option when your racing application requires that last 5-10 horsepower. If you're looking for the maximum available horsepower, this is your most cost effective option. Jig-welded U-tabs for bolt-on installation and are available in ceramic coated, stainless steel, and mild steel. Used by many of the top teams in Pro Stock, Comp and Super Stock.

Note: Merge collectors are not usually a ''bolt it on and go'' part. In order to realize the full potential of this collector design, dyno testing is recommended for proper camshaft selection. Sold Individually.

first time ive order from here and my experience was great! shipping was crazy fast. and they had the best price shipped on the 2jz arp head stud set i could find. also how on their site they actually list if they have the part in stock and how many which is very helpful. ive payed for parts to find out the vender didn't even have them available. which lead to more down time. and we all hate down time :)

I ordered an Optima battery for my truck after I did a Google search for the battery. Autoplicity was the cheapest on the Web. Even cheaper then eBay. They got me hooked. Thanks Autoplicity

Best price on the internet. A lot cheaper than amazon, so I was pretty surprised.

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

I ordered a Flowmaster cat back system for my 2012 F-150. The order arrived the day they said it would and the product came at a fair price. Well done.

Excellent customer service. Treated me very well. Issued a refund, no problem. Thank you!!
