So I was tearing down a bumpy road the other day and one of my mufflers basically fell off. The mufflers are all original and pretty old and rusty. I'd like to take this as an opportunity to move to a dual system, headers to mufflers, which I was planning on anyway - I was just gonna wait until spring.

I've been reading over the exhaust postings but there's more information that I can digest. I'm not really sure of the ins and outs of the different options available, I'm just looking for something that will last many years and give a performance boost. Right now my '75 is stock but I'd like to do performance mods over time. I read that this is the last year where the frame has holes for dual pipes. From what I've read I can get away with ditching the cats if I do classic/antique plates.

What's the most straightforward way to go about this? I see corvettecentral has a whole system for $629, which sounds very reasonable, but then I see a ton of discussion about Flowmaster vs Magnaflow, Pypes, Allens, 2" vs 2 1/2", aluminized vs stainless, X-pipes vs straight, etc. etc.

Is there enough to this to be worth investigating or am I better off just grabbing the complete system for my 350 4spd? I drive it as much as the weather allows, no racing or anything like that. Certainly not a show car.

 

headers, and 2.5"" pipes will take you as far you want to go.mufflers depend on what sound level you. want

 

As long as it can be reasonably quiet at low RPMs for main street & residential neighborhoods I'm not too picky.

The corvettecentral kit comes with Magaflows which seem to have positive reviews around here. Anybody have experience with the Patriot kit offered here?
