exhaust question
Well, my exhaust has some pinholes in it and a cracked muffler. It is time to replace the old rusty ones with some new ones. I have a 70 k20. I would like to run 2 1/4 or 2 1/2 inch pipes. What mufflers and pipe diameter should I get to get a sort of stock sound? By that I mean what will give me a nice sound with out having to wear ear plugs. Thanks in advance for your opinions.

Re: exhaust question
Certainly no bigger than 2.5. I like the BIG magnaflow mufflers, I have them (duals) on a couple of big block vehicles, including my truck. Quiet at cruise but angry at WOT, and no droning.

Re: exhaust question
Here's one to consider. Good quality basic dual mandrel bent aluminized 2-1/4" system with choice of 'stock' mufflers, glass packs or no mufflers plus 15% off and free shipping. Designed for ram horn manifolds.

Re: exhaust question
I am running 2 1/4 with 50 series flowmasters. Nice sound not loud at all.

Re: exhaust question
I need a complete system on my truck and the muffler shop recommended going with 2 1/4 pipes cause I have a stock 350. I like your system and the way its laid out. Do you have a Big or Small Block, Stock or beefed up engine?

Re: exhaust question
Thanks Jim, that's great to know. Once I get the engine rebuilt I will be ready to exhaust. Now, I am taking my sweet time, but I look forward to hearing that sweet sound.
