Need an exhaust

Being super nosey. How does the exhaust look from behind of the car.  Is the box hanging below the fuel tank?   Do the underslung pipes touch the ground ever.   

I remember looking at the factory car at Gurston and thinking that the pipe ( bit painted silver) was the lowest point and would be the first impact point. Looks hateful in the flesh and you are going to notice a difference with the new system, not only sounding like a sportscar but also a bit more power for free.

Does anyone have recommendations for exhaust joint poo? Back home in NZ/Oz we have CRC Exhaust Cement thats like wet clay in a tube, which expands with the heat and 'fires' hard.

I have a new standard 'tin' gasket for the headers at the exhaust ports, which I assume is a dry joint. Does a smear of some sort of poo help? (the round headers are slighter bigger than the oblong-ish ports and gasket). Or, drop the gasket and use poo?

[BigSkyBrad]

See above...

Manifold gasket and/or sealant?

Measurements to help locate the silencer boss on the chassis?

Reachin' out here, guys!

[Thrustyjust]

Gasket is dry , just bolt it up. As for hole, I dont think anyone will give an exact measurement. Its a kit car and the body can be 5mm or more out of location to be exact. People have given you pointers, but for someone to say is 20 mm from here, may upset you, if it was wrong. The factory way is to drill from the inside . Yes, you have inner panels , so either removal or dremmel out a corner ( is hidden by the seat) is the only real positive approach to getting it right sadly.

@Thrustyjust Yeah, fair call on the measuring. Looks like its going to take equal measures of luck and cunning!

So I went for a Westfield one because ,amazingly, they had a system and cover in stock and will be here tomorrow, so hopefully fitted by the end of the weekend and back on the road. Some may feel I've sold out, but given the low tune of the car, a custom pipe would be overkill.

My big problem is finding the boss for the silencer mount. I really don't want to have to remove the inner paneling to get to it. If two or three people could measure their cars (late 90's/early 2000's) for me so that I could take the average to cut a hole in the outer panel, I would be very grateful. I phoned the Westfield tech dept but they were no help. I would need (a) the measurement from the vertical crease in the side panel to the centre of the mount bolt, and (b) the measurement from the lower edge of the panel to the centre of the bolt. If anyone can help me out with that, that would be superb.

 

Brad, if you're needing a wee hand, put a shout out to the Clan as someone may be able to pop over to you .. many hands et al! The problem with getting measurements from someone else's car is, as you know, no two cars are exactly alike. It's best to offer up the pipes to your car and 'measure twice, cut once'! 

[BigSkyBrad]

Sorted! Don't know why I didn't think of it earlier - couldn't see the wood for the trees.

I googled for the clearest pics of chassis' and downloaded, zoomed and printed off two of them. With schoolboy maths and scaling, I worked out the distance from the rear seat mounting holes to the silencer boss on both and struck the average, and with a hole saw matching a blanking grommet I had laying about, I drilled the inner panel looking for the boss and was only 5mm out from the centre (phew!). Then drilled through the boss and through the fibreglass, then holesaw'd from the outside.

My biggest fear was that because it left the factory with an under-slung exhaust with all the extra tabs for that welded to the chassis, they never welded the boss on for a side exhaust.

She'll be back on the road this afternoon.

The missus and I have gone two mile up the road and back... OMG, it's loud! (what have I done!). With ear plugs in, and the missus with her custom-fitted ones it was rude even on an even throttle at 65mph. I thought the cat option might quieten it down a bit. Yeah I know, that's what everyone else's car sounds like - I guess I've been spoilt with a civilised refinement of sorts with the sound behind us and conversation at reasonably normal level, and I'm sure we'll get used to it. Now with the headers and the silencer bracket in place, a different (quieter) silencer could be obtained/made if we really can't live with the noise when touring.

[Thrustyjust]

Factory box should be sensibly sounding . But saying that, it should quieten down after a while. My exhaust can was slighty too loud for IVA (99.5 Db) although he let me pass , but now its nowhere near as loud now it has sooted up. So, dont massively panic , just try and drive it a bit more.

 Defo be doing that, will try to get as many miles down before winter forces her into the garage for the worst of winter.
