Here is a picture of the set up I made. If you look you can see the 2 exhausts clamps on there. I made it to where the muffler delete pipes I made can slide snug over the stock pipes where I cut the mufflers off. I also have a set of magnaflow mufflers that can slide on the same way and use the same clamps. It really sounds good and I am glad it is this way b/c I am about to put catless DPs on it and I am afraid it will be too loud and if it is I can just throw the mufflers back on.

No. ENGINES like a little bit of backpressure (immediately out of the exhaust port)...NA engines like/need a little bit of backpressure, but our Turbos' provide the backpressure to the engine.. Therefore, what you're thinking is actually reducing backpressure from the Turbo....which is desireable.

I might go back to that
Cost me all of 90 bucks.

No engine ever needs backpressure, only exhaust velocity and scavenging, which may be brought on by less free-flowing exhausts. Top end will suffer from restriction. Go as wide as you can until you start experiencing diminishing returns.

That sounds pretty badass..I like. The idea of being able to install/remove the exhaust easily is pretty good too.

Muffler delete has No drone?
Guys-
I ended up spending about $400 in total for my setup. Here's what I did. 1. First, I had the muffler shop saw off the stock mufflers and tips. Then I had them install two Magnaflow resonator-type mufflers (i.s. style 10414) and rewelded the stock tips on. The sound was great, the I6 sound was back! However, after a couple of the weeks, the drone at around 2k RPM just got too crazy, especially cruising for long distances. 2. I went back to the shop and they said the only that could be done was to go with a different, larger muffler (i.e. style 12226). The resulting sound is much more mellow than the original setup but still throatier and deeper than stock. There is basically no drone either. However, it lost a lot of that I6 sound, the awesome rumble at idle, and has a bit of the harshness of the stock exhaust. Have you guys had similar experiences? |

Haha drag engines pushing thousands of horsepower are a bit different, which I think you are smart enough to realize. For the average <100hp/liter car, some backpressure is desireable.

They are 4 inch tips, they are just as good of quality of any tip out there. They look exactly like dimisa tips but bigger and I got them for 28 bucks to my door from a car parts provider on ebay and they are nice.

Another alternative way of doing this would be with v-band flanges. That way for those of us up north where stuff gets salty/rusty/etc (ie a slip fit system sucks for swapping stuff out if needed) it would be simple.
I may look into doing this in the spring. Solid idea, easy to accomplish. The sound is fantastic as well.

The the not so smart person says and knows why back-pressure is bad, knows the principle of designing a good performing exhaust, and the so-called guy who thinks he is smart, is actually the one who doesn't know what he is talking about..the former is me, the latter is you.

Here is some useful info on backpressure... http://www.uucmotorwerks.com/html_pr...torquemyth.htm And if you search around you can see that a little back pressure on a turbo is good, less it better but some is needed to keep the turbo from spinning too fast and blowing.

So you post something that supports exactly what I said. You say "if I search around you can see that a little back pressure on a turbo is good, the less it better, but some is needed to keep the turbo from spinning too fast and blowing"?!?! What? That is what a wastegate is for...gheez. Wastegates control turbine speed...not exhaust backpressure. Exhaust flow goes over the turbin wheel and spins it, the wastegate then controls how fast the turbine spins and controls the amount of gas that can pass over the turbine wheel. I don't need to post any supporting evidence...but you found some and that is exactly contradictory to what you posted and supports what I said. Backpressure is bad. For eveyr 1Hg is backpressure you lose about 1hp. It is that simple. Physics. A good design for an exhaust accomplishes two things, it reduces back pressure, and it accelerates the velocity of the gases across the entire RPM range as best as possible.
