Exhaust

My hunch is the lack of back pressure made the "get up and go" to "not really wanting to go". Sounded like sh** and was the biggest waste of money. I thought I could out think Larini, Quicksilver, VAP, etc... Learned my lesson. Let the experts do the trial and effort; I'll pay for their effort and engineering.

A guy near me has an older Saab with straight pipes. Evidently he thinks it sounds great but it isn't. About the worst sounding ghetto piece of crap I've ever heard. He's an older guy (40s), moved into his parents' basement about nine months ago. I've considered using Expando-foam insulation inside his tailpipe some dark night.
It's horrendous, that gawdawful noise it makes.

I often walk my dog on the main street and hear different cars go past, trucks, mustangs, rice burners, even some cars like corolla's with obnoxious loud exhast's. I realize that when I look at them they are so proud of that crud that they think I glance in admiration. It is not!
To each his own, their car their choice. I just hate when someone else's choice assaults my senses!!!

I agree, making a car louder just for the sake of noise is horrendous. I remember a video posted on here a while back by a guy who "enhanced" his XKR exhaust and in the video people would stop and look at his car, he thought in awe over it's magnificent sound.

LOL, if we were all the same life would be very dull!!! I can't claim that I haven't had my moments, when younger I always had car stereo's that were like rolling concerts. I am sure I had more than my fair share of irritated people around me. Perhaps it is unfair of me to judge what others feel is music to their ears, keep on keeping on!

While there are for some reason a LOT of ricers who drive near my house with modified exhaust, I can at least appreciate the ATTEMPT they made to sound cool. Even though it bugs me, I can't complain TOO much.
THAT.... ONE.... SAAB..... is just an idiot. There is NO sense to what he has noise-wise. Not a sane person on the planet would appreciate it.
There is a difference between being a noise-maker because you like something to just MAKING NOISE.

not that i don't believe it, but, i know i couldn't care less if anyone looks or not, and i've never met someone who said that's why they customized their exhaust.
i can disagree with the sound of an I4 or V6 though -- i don't think i've ever heard one made good through any amount of effort. i suspect a lot of those people like the turbo noises more than the engine.

I dont know how you got the idea that it's not performing optimally. As was said before , you need proper ECU calibration for additional exhaust flow , and boom you have power back plus some extra... Easy breezy.. I do it all the time .

OK I have the ecu reprogrammed so that there is no loss of power

Just keep in mind not many tuners know how to do these cars properly as Complicated ECU to understand. If you need someone who knows this well , you know where to find me
