DUMBEST muffler guy EVER!

[Sircnay]

So I went to a local muffler shop and asked the guy first if he could fab up some piping for my intercooler. His answer, "I don't mess with that stuff."

THen I ask him how much he would charge me for a 3" exhaust. His response, "I wouldn't do that, you'd lose a lot of bottom end."

I figure he must not realize it's turbocharged because I didn't tell him. "It's turbocharged."

"You won't need a 3" exhaust unless you're pushing out 500hp, I'd suggest a 2-2.5 inch exhaust."

"I don't want any backpressure on my turbine."

"Yeah, but you'd lose lots of bottom end."

"My compression is low enough that it doesn't matter, and my engine is rev happy, so it's not like losing it would be that horrible."

THen he goes on about the bottom end thing. So I shut my hood and get in my car and leave, because he obviously doesn't know a lick about this.

He should realize you understand the consequences of your actions, shut up and do it.

that's my biggest pet peeve with people that offer certain services. if i ask for something specific, regardless of what you think, do what i ask. that's what you get paid for. the guy just let money walk right out the door.

Bottom line is: no matter where you go and what you do, people know more/better than you do. The trick is to just not argue with them. Just agree, and walk away. That's what I do, it leaves less aggravation.

Not everyone understands turbos, and on most cars 3in is far too much. Even on turbo-ed cars, 2.5 will usually do (well, for a while, as in, a stock SR20DET, for instance, will do fine with 2.5"), so cut him a little slack.

Don't say that! Oh nos! Then they can't justify their massive fart cans with stock SR20's!

:pface

[nametakennow]

That was confusing... what I'm saying is that a stock turbo engine doesn't require a 3in exhaust, it'll get along fine with a 2.5. It's no hurt to get a 3in though, maybe a slight loss in bottom-end, but it allows room for more power later anyway, and thus is a sound investment. A 3in exhaust on my car would be overkill, because I don't plan on big power. I might* eventually do a small turbo (T3 or something), but I'll probably stick with a light all-motor because FWD is so limited, and daily driver reliability is a necessity.

[SeVa-S13]

Oh, believe me, I know plenty about the workings of Turbos and Turbo-related systems; I love knowledge. But I'll take any chance I can get to crack on people's fart cans.

i thoguht you cannot lose low end power through your exhaust on a turbo car...as far as i knew, the turbo spools fastest w/ an open dump pipe...

[TrunkMonkey]

turbocharged vehicles hate back pressure. period. 3" piping with a t2small turbo will do more benefit than harm. regardless of the size of turbo, the more psi you plan on pushing, the more you benefit from the larger exhaust.

[MainEvent212]

that's what i thought

[Cold_Zero]

I thought about getting ride of my exhaust from the turbo back. Just fab a downpipe that sticks out the side of my car so I can melt the paint off other cars in traffic.

[MainEvent212]

:ylsuper my sentiments exactly

[skydragoness]

If people get away with putting 3" n1 catbacks on stock KA's and have little complaints about their bottom-end power, i highly doubt a 3" catback on a turbocharged vehicle is going to *hurt* at all.

The guy was a moron, you wouldn't want someone who doesn't understand the concept of how a turbo works working on your car anyway.

[Sircnay]

Oh yeah, most definitely. I was getting scared when I saw the guy. He had a mullet/mohawk with curly hair. He had flame decals on his welding mask and he was missing teeth.

Yeah... what a moron. Ugh, now I have to find someone competent with a Tig welder.

[nametakennow]

I doubt it would hurt in this case too. What I meant is that there is some turbo lag, no matter how small your turbo, and that time that you're running with no boost you lose a little power. Then again, when your boost hits, it will hit harder, so it's probably worth it

just remember, muscle cars love backpressure and he sure sounds like a muscle car driver

[MainEvent212]

um, just as a side note, i'm highly doubting the validity of the last two posts :rolleyes

[Hijacker]

you doubt me!? just dandy...

[MainEvent212]

yeah cuz as far as i know those muscle car guys love to run headers and straight 3" pipes off their big v8's...but thas jus what i've seen...and i'm also doubtnig the post before yours because as far as i know, the more open the exhaust, the faster the turbo spools

[Sircnay]

Oh god, I just talked to someone who actually went to his shop to get stuff done. Yeah, he just simply welds up exhaust leaks. This is great. Fresno officially has NOBODY that is competent, I'm moving.

just remember, muscle cars love backpressure

A common misconception: NA cars like high exhaust gas velocities, not backpressure. It just so happens that this is usually accomplished by using smaller diameter exhaust pipes than turbo cars since turbo cars also want exhaust gas velocity but it doesn't have the same scavenging effects as it does on an NA car. Having as low a pressure as possible after the turbine is what you want so that it spools faster.

ps: sorry if this makes no sense, I'm falling asleep.

"Dude do you even know anything about turbo engines?" -me in a situation like that if i was having anything less than a good day.

Its your car, your money, your decisions about it, and for some reason this guy still feels like not taking your money? At least he knows where to get a good lobotomy.

[Hijacker]

i was actually kidding about that statement first off....i like to poke fun at mullets and muscle cars

second, old carbed muscle cars from back in the smog hog days needed back pressure. the unspent fuel would stay in the cylinder essentially double loading the chamber because it couldn't get out through the valve due to a constrictive exhaust.

The Pontiac dealership....

[Sircnay]

No the saturn dealership, obviously none of you have dealt with the Saturn dealership. Remember their Saturn family BS? That was some scary stuff.

[Megaseth]

haha, thats right, i do remember that stuff.
