Received a quote for $100.00 to remove center resonator, and <B>weld </B>new straight pipe. They characterize this pipe as "aluminized stainless steel". Is this SS or aluminum?

Exhausting Trivia.........<p>The straight pipe was never really invented..... it was more <i>un-invented</i> when in 1917 the muffler was invented by a Ms. E. Jones....... <p><br>

It's aluminized SS, i.e. hot dipped aluminum coated stainless steel tubing. Much better corrosion (oxidation, as in rust) resistance than plain stainless.

Re: JRL Patented Mod (Short Circuit)

For a point of reference for you, I had straight pipes welded-in in place of my rear muffler on my V70 R for $80, using aluminized steel pipe. Done at a local Monro muffler shop. They didn't have stainless steel as an option for me. It works, but it doesn't look pretty. My friends can't believe the sound out of my car now. Sounds awesome at wide-open throttle. If you have this done, it will completely change the character of your car, and increases the fun-factor by 100%. I call it my anti-Volvo soccer Dad statement. No offense to soccer Dads, and I may be one myself some day. My wife said "You paid how much to have WHAT done? And what's that do?" Some things are hard to explain.

If we start from the engine to tail, you have the catalytic converter, then the resonator, then the muffler. Are you saying you kept the first 2, but straight piped the muffler part? I wonder what sounds "better" - removing the muffler (only) or the resonator (only). <p>Is my visualization details correct?<br>

It's exactly what it sounds like "aluminzed" is a anti rust coating they put on steel pipe.<br>Unless you're keeping the R for 10 years, it's just fine, good stuff (and cheaper)

Agile Auto did mine for a little bit more than that. I've also dealt with Pro-Imports out in Gaithersburg. Agile seems to be primarily Subaru/Acura etc, and Pro-Imports is a BMW/VW/Audi tuner shop, but they both do quality work.<p>I was getting absolutely RIDICULOUS quotes from local muffler shops, which seemed reluctant to even think about doing it, or wanted >100 unless we can't use clamps, in which case it will be more.. riiiiigiggght.. buhbye.<p>

Re: JRL Patented Mod (Short Circuit)

Okay, there seems to be some confusion here.<p>There is no such thing as "Aluminized Stainless Steel". That would be pointless. Stainless Steel is the stuff you want to use as it will yeild the best durability.<p>Aluminized Steel is exactly that. Regular SAE 1008-1010 CRS (Cold Rolled Steel) that has an aluminum coating to prevent corrosion.<p>Since stainless steel has better corrosion resistant abilities than aluminum "plated" steel, it is the preference, but solid SS is much more costly, and more rigid, making it much more difficult to work with.<p>The downfall of the Aluminized steel is that, just like with paint, if you scratch the aluminum surface through, corrosion of the steel will begin.<p>There have been many debates on many car forums, when considering cost which is best, Aluminized vs SS. Do a google search.

Yes, it's a good thing. Let them weld it up and don't look back.

Re: JRL Patented Mod (partridge)

Partridge, I'm going to HPR in Glen Burnie, MD. This is their website: <A HREF="http://www.hprcustoms.com" TARGET="_blank">http://www.hprcustoms.com</A><p>If you look at their site, it's quite impressive. I've bookmarked these dudes for their tinting work, not thinking or remembering that they do so much more. Just check out their products & services capability. When I did a google search on muffler shops, they popped up. I did call Meineke & Midas, and got same $$ quotes, so I decided to go to a place that actually does this for a living for the performance-minded. I'll let you know how it turns out with these guys.

Re: JRL Patented Mod (JRL)

JRL, what's your opinion of the sound generated from your resonator removal? Would removal of the muffler, instead, acheive the same sound, improve it, or ruin it?

Once you chop the muffler out the entire exhaust is finished and what you have is what you'll have forever unless you want to buy an entire new exhaust

Re: JRL Patented Mod (Short Circuit)

Yes, you're right. I have 2 straight pipes in place of the muffler. I'll be the first one to say that this mod is NOT what most people on this forum are looking for when they want more of a performance sound, as it IS pretty loud at certain RPMs. Too loud for most people, although I've heard much louder from modded Honda Civics. If it is your only car, I would say to just do a center resonator removal (although I have not personally heard what that sounds like). For me, the muffler removal was just right. For longer drives, I uh, take the LS430.

Re: JRL Patented Mod (Short Circuit)

I just came back from having my center resonator removed.<br>The down pipe is SS, the twin pipes aft of the resonator are SS. <br>The car sounds no different at idle inside or out. There is a slight increase in sound inside the car at WOT but nothing bad. There is a very nice deep tone outside the car under hard acceleration as it goes away from you. This is what the car should sound like.<br>I was having issues with the resonator hitting the prop shaft when driving in rain so this has now resolved that issue. The fix from Volvo for this issue is to install a new style bracket that looks like the old one at the bottom but has "fingers" that reach up over the exhaust pipe and keep the pipe from moving upwards where it can come into contact with the prop shaft. A buddy just had the fix done on his R and he said if you snag the bracket now, you have a better chance of doing damage. <br>So a half hour of time and $72 later, I now have an R that sounds great.<p>I'd not hesitate to do it if you have been thinking about it.

They did a great job. Cut out the resonator, bagged it for me & gave it back, and installed aluminized SS, welded, and spray-painted a high-temp engine black paint. Exquisite job. As the guy drove up to me to return the car, it sounded GREAT. I had him rev it while I was outside the car, and the sound is demonstrably better & different than stock. Deeper and slightly, slightly more throaty. Higher revs pronounce this sound from the exterior. Interior-wise, at a dead stop @ idle, I notice zero difference. As you pull away, slight throaty sound, but extremely composed & mellow. As the revs increase, general road noise come into play, and the sound gets drowned out. Deep WOT gives a nice tone; different than stock...definitely more exciting/better. In terms of drivability, I could swear that the engine seems more "compliant". For example, going into first gear and then quickly letting go of the gas - stock would, most likely, kick the engine a little and car rocking might occur on occasion. With resonator removed, engine gracefully releases power. No rocking whatsoever. Hard to describe. In 2nd & 3rd gear, same thing. Wind up, wind down. Very, very nice. Super glad I did it. I'm extremely pleased. For folks on the sidelines thinking about ANY exhaust mod, this would be the first thing I'd do before spending the much bigger bucks. I could definitely envision what it would be like w/such a bigger mod, but now, I'm not so sure it's really needed.
