Default [PICs] EM headers / 3inch exhaust back

Below you will find a few pictures of my new exhaust. The installer cut off the end of the seatbelt mounting bolt, not happy about that. I wish he had used a narrower x-pipe or bent the pipes a little. otherwise, VERY NICE work.. happy with it...

Looks a little restrictive still - were they out of 4" pipes

All that sweet exhaust and he's worried about that milimeter shaving off his seat bolt!!! I wish I had such problems.

LOOKS AWESOME. Love the X pipe. Let us know how it sounds and performs. I'm looking to do similar exhaust myself.

Thanks... don't get me wrong... The exhaust work is very nice but I wish he had bent the pipes a little instead of cutting off the end of the bolt. Not a big deal. Just the thought of cutting something off on my car doesn’t sit well.

The car is LOUD!!! I drove home with the power effects open and it's loud. Still has that "race car" (not my description) sound but the tone is higher and of course louder with the x-pipe. I think I lost a little low end torque but the car is more responsive, more alive in a way..

He did no harm cutting the bolt off. If you ever remove it, it will make it a little harder to start threads, but it will not affect the strength of the bolt.

In fact, you're probably better off as now it will conduct less heat throught it to warp plastic and rust the bolt.

Nice install.!

Really nice job. Did you have the 3 bolt flanges welded on your headers or has EM redesigned them?

ok... I need to spray some paint over the area he cut because it's exposed metal now, but not a big deal.

thanks... I asked him to flange the EM headers. The tuner installed the Wide band O2 bung.

I had thought about doing the same to mine. I have not had much luck getting the slip fitting and band clamp to seal. Could be I am doing something wrong though.

Mine leaked too... one reason why I asked him to install the flange.

Cut slits in your slip fit pipe/cat, and the band clamps should work fine.

I have never been able to get a good seal with that 3-bolt flange. I am converting my Hooker 2151 to V-band clamp instead.

Can you drop the entire exhaust now? If so, do it and paint the entire exhaust with a very high temp ceramic paint. It will last a lot longer and even look better. Just an idea.

Nice exhaust. Should flow well!

Whats with the large plugs in the headers?

Also get ready for a warm cabin. With the pipes as close as they are to the body you are probably going to need some heat shielding. I am running into this problem right now.

Nice installation. Robert does a fine job on fitting them into the space available.

Those 3 bolt flanges are very handy when it comes time to do other things like replace the clutch you'll blow up, or a Hurst shifter.

What brand of cat are those? My random techs don't have the full heat shield, only on the top.
