straight pipes vs. performance mufflers.

does anyone have any opinion or ideas on this subject or related links? Since the goal of a performance muffler is to minimize back flow, how is it better than straight pipes?

Straight pipes have severe drone and are rather raspy on acceleration, also poppy during deceleration, but some people like that sound.

Here's some good data for your question:

But, even with that information, I still have a simple muffler delete. I like the noise level and tone I currently have. Eventually, I want to even out the inconsistency of the sound and performance of the straight pipes, though.

Plus, I live in NJ and inspection is almost impossible to pass

Until you do something to your exhaust up near the engine (where scavenging is important), the only difference you're gonna see is up to 9 rwhp (as you can see in the link posted above).

After the headers & the front cats, NO change is gonna help over 10hp guaranteed...
(Well, unless you mount a remote-turbo! )

I wonder if straigt pipes could be insulated where they aren't visible under the care. @netkeym: cant you just say it has a blown hg and its parked on the street so they'll give you tabs?

Interested in this discussion. I have true dual exhaust with flowmaster tips. (I know) but it sounds good I promise. However, my exhaust manifolds and front cats are stock. If I was to get kooks or mustang headers I would have to do away with the front cats correct? Not a problem if so, I live in East Tennessee so no inspections at all.

most mustang headers won't fit due to steering shaft placement in our cars.

I know. Actually I thought they could be made to work by modifying one of the driver side pipes.

Dont do straight pipes. It sounds like a boat motor at idle and the drone will make you want to put a hole in your head to releasse the pressure after a long drive. I know from experience in my Tbird

If you do this could you make a second set??

Seriously though I would buy the headers ship them to you and pay you for the work.

I wish I could. However I can't weld very well. There is a couple of good shops here in the area that I have faith in who will likely be doing the work. Does the author of the how to not do that for people? In any case, if you don't have a shop in the area that will/can do it, and the shop around here does good, then you could ship it to me and I'll take it to them. We'll see. This is likely not in the real immediate future anyway. Just seen, a relevant post and took the opportunity to ask the question (which was never answered )

Haha. Yeah I know. I'm scatter brained. The question was, if I did run long tube headers if the front cats had to be removed.

If I remember some bit of tccoa tech a pair of hi flo cats actually help smooth out the flow of air helping your car run better. So I take it a performance muff could help in the same way. Straight pipes are ok as they dont hinder but they dont help improve anything. I can run straight pipes but would I want to hear all that noise? Hell no! Performance muffs help the exhaust flow well and not give you redneck levels of open header noise seems like a no brainer. And trust me I like loud but Id rather hear my stereo or the engine itself.
