Exhaust request

[dstang01]

Hey, Id like to hear what a set of flowmasters and various midpipes ( O/R X, O/R H, prochamber) sound like on an otherwise stock or bolt on 5.0. Also, what do headers do for the sound quality? Thanks

Check my sig.......

Long tubes tend to be deeper/sound better while i think shorty's are louder. I've never ran aftermarket shorty headers. Only long tubes.

Ive been on that site before, its very good, but its hard to tell what ones are on stock motors and what ones arent, I was wondering if someone could let me know. I hear longtubes dont make a huge power improvement over shorties, but it might be worth it for a better quality sound.

On a relatively stock motor/mild build, no they aren't going to make that big of a difference, but they sound sweet. On a built engine, longthrows will start making a difference though, so if you plan on building your engine, might as well put them on.

Would a long tube, O/R H, flowmaster 40 combo give me the deep, howling kind of sound Im looking for without being raspy and poppy? I also want a nice tone at idle (some of the 5.0s I hear sound kind of quiet at idle), do long tubes help or hinder idle volume (in your experiences)

My plans for the car are a 300rwhp street car (using a mild h/c/i such as the tfs or explorer setup with a cam) and then maybe some juice. Ill be leaving it stock with a few bolt ons for a couple years though, so will having long tubes and a free flowing aftermarket exhaust damage my stock motor at all? Will it provide too little backpressure or anything?

Also, do long tubes and shorties require different midpipes? I know on F bodys you need a matching Y pipe with the addition of any aftermarket headers, but is it the same deal with stangs? Do the stock headers, shorties and long tubes all match up with the same mid pipes? Also, how is ground clearance issues in stock ride height cars?

(wow.. lots of questions im sorry. thanks in advance for any help!)

On the sizes ...

For LT's ... you use a LT specific mid-pipe. (shorter mid-pipe)


For shorties ... you get a shorty specific mid-pipe. (longer mid-pipe)


Stock headers / manifolds are same length as shorties.
