I Have A 97 GMC Sierra Regular Cab With 5.7 Vortec Motor But For The Exhaust I Want Something Loud But Dont Know Whats Actually The Best System
Flowmaster super 40. Most popular or magnaflow
If you don#x27;t have to pass emissions go with headers and cherry bomb glass packs and turn outs. Cherry bombs are cheap and have a old school sound that is recognizable. The flow masters and stuff are cool too but I find the best sound is cherry bomb glass packs. Just my opinion.
If you want loud try a cat back with no mufflers. Best would be a long tube set of headers, an X style crossover feeding a pair of flowmaster mufflers. Dual 3 inch should be right for a modified 5.7, but 2 1/2 would be ok for a stock 5.7, not much difference between the 2 under 5000 rpm Big open glasspacks are low restriction, and sound nice. There are glasspacks 4 feet long. With a muffler, the bigger, the better. Side exit exhaust is louder inside the cab than rear exit tailpipes, especially driving by buildings. Louder yet is side exit in front of the rear wheels. Any muffler shop can give you many options. You have lots of room under your truck, you have lots of options.
