Quick Comparo>>> Perrin vs. Motiv Overpipes
 

Everyone on this forum seems to chat up "beautiful welds" whenever new exhaust hardware gets posted.

The welds on the motive piece here are something to aspire to, truly. Those are good welds.

Both items are great parts. Just wanted to show them side by side really as you never get the opportunity to see them that way.

I have the motiv. now seeing side by side it appears to have less angles than perrin

oh and I would like to thank motiv for all the nice add on stuff and swag I got with the pipe.

new bolts
new gaskets

and a sweet ass tshirt.!!!!!!!!!! which im wearing right now. @MotivConcepts

I forget the technical term but the Perrin piece almost looks like the welds on the flanges were done by doing individual little spots all the way around as opposed to properly working the bead. Rather large divots between each "dime." Might not be the case, but the Motiv definitely has the superior welds of the two. I'm sure functionally both are fine. :)

so which is better? the Perrin has better gaskets but the motiv has better welds? how do you chose?

I would not necessarily say the welds are "better" in terms of how they will hold up. The welds are definitely prettier but the Perrin is welded damn good.

With Perrin you have
1.) Flanges are CNC machined from 1/2" 304ss to reduce warpage and leakage over a long life.

2.) Flanges have a CNC'ed inside lip to compensate for the thickness of the tube. This eliminates the inside lip that can cause air flow disturbance.

3.) They use expensive OEM grade multi layer crush gaskets for a sure seal that will last.

With Motive you have $30 extra bucks and still a damn good product.

Hard to not recommend either.

I personally want to chime into this here. Yo, over at f86speedfactory got me into the motiv concepts with my hks el header setup. I was slightly worried because I haven't heard about motiv, but holy wow for the money that your paying vs the quality, the motiv concepts looks EFFIN AMAZING in person! The fit is perfect too! my muffler guys that installed my motiv overpipe and front pipe were saying that it was a perfect fit!

For those of you that are worried about the overpipe rubbing on the subframe or sway bars, which I'm running the cusco thickest sway bar, there is enough clearance that you can shove your fist in there. Motiv FTW!

just fyi, my setup thanks to ft86speedactory, hks equal length header, motive overpipe, motive front pipe and ark grip catback. perfect fitment.

Not owning ether, but leaning to Perrin. Both are works of art!! You could have ether on a coffee table as a conversation piece.

Just want to pipe up regarding the Motive over pipe. It's a quality item, but I have concern with the double weld on the inside of the flanges and the outside of the flanges. This 'may' be of concern as a cracking point from thermal expansion leading to fatigue over time. This may not be of concern in the lifetime of the car for 99% of people, but it was a slight concern to me. Please note, I'm not suggesting it's a poor quality item, it's excellent quality, just keep that in mind.

and is there any difference in the sound?

Would be interesting to check weight of the both pieces on the same scale. Also, very interested which one allows more clearance vs. the front sway bar. If anyone had experience with installing both - would be very interesting to hear!
