Question about exhaust (making one)

[samholwill]

Hi all, I've been after an exhaust for a while and havnt really found anything, I've done a bit of research and am thinking of making an exhaust. Firstly to buy just a centre section off eBay, cut the flanges off and weld them onto a bit of stainless steel tubing from B&Q for £10. Weld a mounting bracket and use as a hanger. Am also thinking of buying a de-cat pipe off a friend as well. So the finished product should be like a peashooter exhaust . I'm just wondering if anyone has tried this before or if anyone thinks it's a good or bad idea.

Cheers for reading. Opinions will be helpful.

£10 for stainless steel tube from B&Q ?

What do you get, 100 MM ?

You can get stealth systems on here for pretty cheap or you could get one made up at any exhaust place.

I guess it couldnt harm to try it though.

(L)1000mm x (W)30mm x (T)1.5mm. May need it slightly bigger but as you said it won't hurt to try aha

Sounds like you're going to ruin a 172 tbh!

Your entitled to your own opinion, but it's different..

pretty sure this will sound s**t. Heard a 106 gti that did the same thing and it was shocking tbh.

remembering bore size can affect performance and bending it up over the rear beam will be lots of fun

My mate built his own using various parts from a magnex system, plus a silencer from Merlin motorsport. Sounded amazing.

I don't really see a problem with it if your a competent fabricator, out of interest do you work in a engineering place and have you tried TIG welding? It can be tricky to master.

Personally i would not use a £10 piece of tubing from B&Q the quailty will be rubbish, you want a decent high grade stainless IMO.

Plenty of pipework available on ebay. Know a few people who have done it for various cars and they have turned out great.

Just to add, its going to be loud. Ridiculously loud.

Your going to attract police attention and I'm sure you can get done for not having baffles / cat in your car.

That is all.

Places like demon tweeks and other motorsport suppliers sell all the bends and silencers you need.

Put pictures and a video up if you go ahead with it

I made my own centre pipe for my VTS.

I used a magnex back box, some 316 grade stainless 54mm NB tube, the flange joint off the magnex and the bend that went over the rear beam at the back was a random make.

That sounded really good with the cams and a cat replacement pipe.
