That's the question ...

I want to see which magnaflow will bolt in without any mods.

I would look at a Dynomax 17749.

Not 100% sure if bolt in, but this is the avenue I would recommend.

Thanks N0DIH

So Dynomax sound like the way to go for not too crazy sound and some power improvement. Thanks for that. Great article...

I am planning on a dual setup. Although for now, funds are low and I must make do with a sound improvement only to my single exhaust system.

Rock auto has the Dynomax super turbos listed as an option for the 472 engine.

Can I install one of these mufflers myself, without welding?

I would take it to a muffler shop but there are none around here that I would trust.
