The Race Roots gaskets were one-time use, yes, but they did a good job- just make sure you're leaving it on for a while!

 

Looks like I might have to go that route if I don't find thick copper/aluminum sheets soon .

Al or other guys. Do you remember what size bolt fits the holes? I'd measure myself but I don't have a caliper handy at home.

 

dans idea is the best one--just go to a hobby store or to a roofing company that does copper roofing--you can probably pick up a scrap piece cheap.
I am about to remove the front resonator on mine .

 

Tried looking for hobby/craft stores that sell copper sheets, no luck. Tried duct/ventilation fabricators that might have aluminum sheets, no luck. I need something at least 1/16" thick and I would probably need to layer it also. If I put a flat edge on the flange from bolt to bolt, I can see some warping. There is about a 1.5mm curvature in the middle between the bolt holes.

I'll try looking for roofing companies. Can't find anything in NYC, dammit. McMaster Carr has copper and aluminum sheets but they are ridiculously expensive even before shipping.

 

if you have a friend--old road signs are a good source

 

Can anyone suggest me the best midpipe?

 

Bhr

 

almost forgot road signs are aluminum. Though I rather pay the $35 for a12x12" sheet of aluminum shipped than risk getting my *** or a friend thrown in jail.

 

Here's a good source for aluminum... They have very low prices, I bought some stuff for my build from them... 6061, 360 Brass items in 7075 Aluminum store on eBay!

 

Finally grabbed a set of Race Roots one time use gaskets for cheap. Very nice gaskets as they are 5mm thick and compressible (will come in handy with my warped flanges).

Unfortunately I couldn't get the damn factory catted midpipe out. My deep 14mm socket is a 1/4" drive. I used my 27" breaker bar which is a 1/2" drive with an adapter to 3/8 then an adapter to 1/4"... Snapped two 3/8" to 1/4" adapters... That's with multiple sessions/days of soaking the nuts with PB blaster.

I thought about cutting the damn bolts out (then redrilling the flanges), but I will decide on what happens tomorrow when I borrow a friend's corded impact. Hopefully he has a 3/8" 14mm deep socket. I don't even know if the impact will fit with such limited space.

This blows.

 

Forever catted lol

Apparently my cat loves me too much.

 

Finally got the MazSport pipe on. Love the build quality, but the fitment is absolute crap. They succeeded in the D in R&D, but completely lacked in R.

The rear o2 sensor is about 3mm from smacking the transmission mount frame. As is the lip of the front resonator. That's just asking the wire of the o2 to snap. Not to mention the placement of the o2 sensor is so far back that I have to either splice and extend the wires myself, or cut the tie down of the other harness so it can reach the o2 sensor's plug. Even then it's extremely short and putting stress on the wire.

The front flange is warped at about 3-4mm between the bolts. I have the strength of Captain America to torque the bolts as tight as possible, so I completely crimp the 5mm RaceRoots gasket in hopes of ridding the space between the bolts. This surely solidifies the statement that the $45+ gaskets are one time use.

The exhaust hanger bar is practically useless. The hanger bar pushes the damn OEM rubber hanger up, so it does the opposite of what its intended to do.

Lets not start with the transmission tunnel braces... We all know that story.

All in all, it's poorly designed pipe, but constructed nicely.

 

I just put one of these on. I was so confused about why the braces did not fit. Glad to see it was not just me. I think I will go the route of making spacers with nuts and washers.

 

do yall think those "braces" are really needed?

 

Strange..other than the issue with the brace that is well known...the rest sounds like a used midpipe problem. I have one that bolted up perfectly..no gaps or problems with the flanges at all
