Does anybody know what is the different between straight pipe and mid pipe if there is no different why would anybody spend over $500 on a mid pipe if a local muffler shop can just install a straight pipe

Straight pipe means they are going to cut your pipes and weld on straight pipes. In my opinion....straight pipe is a cheaper route. And like anything in life you get what you pay for (sound quality). GS is about a $50,000 car why be cheap

Thanks For Your Advice

Straight pipe means you get rid of your mufflers and maybe also the catalytics converters. Do this if you hate your neighbors and if you want to have teenage boys drooling at your car when you drive by a school.

Mid pipe is the section of pipe from the cats to the mufflers, implying you are keeping mufflers. When you get an aftermarket "cat back" exhaust, it likely comes with a mid pipe to adjoin the cat to the upgraded muffler.

Thanks for your respond I did purchase a brand-new mufflers Invidia Q 300 it sounds the same as my OEM mufflers to increase the noise I need to add Midpipe between the muffler and the

Catalytic converters Is it Warth more than $500 ??

Or a straight pipe will do the same thing?

Thanks

Not sure. When I first installed the mufflers, the noise was very noticeable until it broke in. It became very settle (very close to stock). That's what led me to getting the midpipe.

I have the Invidia Q300 with midpipe. If I drive it normally it's as quiet as stock. However, if I get on throtte it's quite loud. Loud enough it drowns out the sound generator.

Don't forget, with a straight pipe you'll also get a lot of drone..

Being in California, I can only assume you'd fail some sort of state inspection with a straight pipe

Do they even do visuals anymore? The guy I go to just connects the ODBC wire and does the test. Never saw him look around for anything.

Cats are actually a federal law as well.

The main cat is in the exhaust header, the secondary cat is in the exhaust line just ahead of the muffler but beyond the oxygen sensor. Here in Texas they only check the OBDIi to ensure all sensors are working correctly. You could most likely run straight pipe as the midpipe but my bet you would have a major drone sound at speed. The resonator (takes the place of the secondary cat) on the Invidia midpipe greatly reduces the drone sound.

That's probably where some of that $500 goes toward.
