Magnaflow has been at Precision Muffler and Brake since we opened 12 years ago and have never had one complaint about them. :D

hahajoey

i hope all this information posted helps people who are in the market of a muffler or exhaust system.

Can anybody tell me what it's like to drive with that drop off in power in the low RPMs? It looks like power comes on 500 RPM later with an aftermarket exhaust, but then continues to build after the stock exhaust power falls off. Issue is that low RPM power. How noticable is it? Any stalling issues? Acceleration? In general, minus the sound, was the vehicle with an exhaust more fun to drive, or less?

Thanks!

That dyno does nothing to help in what hahajoey is saying. Your catback might make 4whp over stock but still might be less than a good quality axleback setup.

You see what I'm saying?

He said there's a reason japanese companies made axleback...maybe they made more power...but magnaflow would have to test both to compare...not just compared to stock.

Cuz I could ____ in the tank and dyno +2whp but that doesn't help me unless I compare it to somebody elses ____.

Ya get me

let's compare joe

Hmm, we're fightin over hp out of a 1.5 liter that has 108 hp at the flywheel!?!

And only one person has posted dyno results for proof!

and the truth is squirrel...its so minimal on a vehicle as is with a few bolt ons...that its without question more for looks, fit/finish and sound. Thats what your buying. Every dyno can be off a hp or 2 hear or there. dyno results don't even mean much with vehicles making 180whp let alone 100 from a 1.5NA motor. At this point it boils down to preference and sheer personal opinion. Its the reason why i posted sound clips so early on the Strup because it meant more then 1whp and the strup looks great.

i just wanted to help a scion guy out,
not tell someone to buy a product just cause
i have it and they should get the same.

i just thought a posted those links as a little help
for people who are reading, and im glad
showpao understands where im getting at.

its not the 1.5 to 5hp rating. and in fact, i posted a link
that had intake, header and exhaust dyno'ed.

im not out to prove anyone wrong, i just wanted to provide
an UNBIASED opinion.

This is because the ONLY flange on the OEM system is at the axle. And damage to the ceramic catylitic will void your smog warranty and cutting the OEM exhaust so close the cat could jar the insides loose and that a $900 replacemtn piece.

That being said, www.vibrantperformance.com will be offering an axle back in the next few weeks as well as a cat back (how the 'coupling' works on the cat-back is beyond me)

I know this cause im their guienna pig! They got a nice xA/B front bar too!

Lip

the coupling is nothing more then a curved piece of metal stock with a groove in the middle. When wrapped around the attachment point it pulls the flared ends of the axle back and "cat" to axle pipe together when bolting it together. Its fairly primative.

As i stated earlier...when using a stock size piping it boils down to quality, sound and looks. Thats what your paying for.

K_Dawg_ONE

It will be 2" as that is what the OEM piping is before the cat (after the header part)

Remember, im not an exhaust god...lol....im just psoting what they were saying yesterday...lol

Guest

Primative, yes. But if the flared piece is not correct, say good buy to that gasket and hello to a burned bumper. The trds,sometimes, do that now, with their design. :?

squirrel

And you'll prolly need to replace the "ceramic"/metal gasket at the attachment point also. Most don't and end up with melted bumpers.

But there is a work around that, especially if you want to pay a few more dollars. Ken at Michael's Muflers has the solution to the problem.

I have less than 1/4 inch clearance on both sides of my oblong tip, and have yet to melt my bumper.

My xB just came with a POS universal muffler and nothings melted...

Disclaimer: I know nothing about tuning cars. Please correct me when I am wrong.

I was thinking of getting Headers, Exhaust, Intake but after looking at the charts and reading the web sites posted I am thinking of just staying stock. I have no dreams of making my car break records at the track. I just wanted to give the car some more get up and go. If getting HEI is going to kill my low-mid rpm's like those dyno graphs show then what’s the point? I have an automatic and I spend all my time 2500-4500 rpm's. If the stock set up gives me the best power in that range then there is no reason to switch right?

Am I reading the Dyno's wrong?

Thanks,
Jason

hotbox05

well from my hei i have increased power throughout the band , i have lost no noticeable low end , and my power starts kickin in just about 2500 so.... and with an auto everytime u speed up yer engine speeds up and if u slam yer foot in it it downshifts into the power.

A $200 Magnaflow muffler based axleback installed sounds pretty good to me.
