Gota love exhaust threads...

Well I want to run my exhaust out the back on my car since i got some purple hornies, it just makes it near impossible to tune and tweak and listen to your car.

My question is what is a good setup to run?
I was thinking bout spintech but they are so expensive!! So what else do yall suggest or could i get away with one spintech? I want it to be loud but sound awesome.

I got headers, a magnum 270 cam, and the rest of the 350 is built. I was thinking 3 inch pipe just cause i heard it was deeper.

And i dont have to worry much about backpressure cause them purple hornies prolly didnt have much. And sound doesnt matter too much as long as its not open headers sounding.

thanks in advance

*AHH crap i posted in the wrong place*

if you want a nice throaty exaust sound I would go with 21/4 no larger than 2.5 on a 350the smaller the exaust the throatyer it will be.

2.5" is a pretty good setup. Sounds good and moves the smoke outta there. I had mine welded up at Affordable Muffler here in portland for about $200 from the headers. If you want a good sounding exhaust at the back, hook up a couple of cherry bombs - $25 at shucks auto.

I use turbos myself, i like a quiet ride, but glasspacks offer a great sound if you want some intimidation

I wouldn't go larger than 2.5 inch. 3 inches and you will start loosing backpressure on the smallblock. Its not the hornies that will make you look backpressure so much as those combined with the larger internal area of the pipes.

I have a moderately built 350 running headers down to 2.5 inch exhaust leading to two Flowmaster 0riginal 40's then straight out the back. They are great. I actually wish I could hear their tone more but as I am in a truck and its all the way out the back . . . all i hear is the engine. Its a VERY different sound up front than out back . . . much quieter up from (though my truck is pretty long which helps).

If possible I would also recomment running an X pipe as this will quiet it down too and even out sound and pressure between banks 1 and 2. When I did my exhaust I just went and purchased 2.5 inch piping, went to a exhaust shop and had them bend it to my specified angles and then went home and welded it together. Total cost was around 180-200 bucks for the system.

What would be a cheap set-up, as in around 200. I want something like flowmaster 30 series, or dynomax's, or maybe spintech but they seem quiet. I want a loud all out bad *** sound. And i will install either a x pipe or h pipe. What would the hornies sound like ran out the back?

*I was thining of some dynomax's bullet race mufflers, what do you guys think? Would it be too loud? The cops arent too bad on us here*

I apologize if my last post was a little misleading. Flowmaster 30/40 series are VERY loud when you get on it. Dont get the delta flows get the originals if your lookin for a bad *** sound. My friends drive a Camaro and Corvette which are considerably quicker yet they conceed that my truck is the most intimidating thing on the street when it comes to sound. My bud says that when I get on it the Flowmaster 40's sound like Demons under the vehicle.

Would my exhaust be too loud if i ran: from the header out to 2 1/2 inch pipe to one dynomax bullet muffler: 4 inch round 16 1/2 inch long and 2 1/2 inch: in and out one each side, to an H pipe, to the rear of the car with two slant cut 3 1/2 inch tips.?

PS What kind of muffler are those? Glasspacks or other kind?

Dynomax race bullets are built something like glasspacks, only with larger non-restrictive core walls. They will be loud.
