How hard/much would it be.., Over to Under Axle Exhaust Options

[95CelicaST]

I have an Over-Axel exhaust system and I was debating on taking it in to have it switched to an Under-Axel exhaust. One thing I am worried about though is when I get my Coilovers put on. Would it even be possible to be so low as to scrape the piping? I think it was Manny who said he doesn't scrape at all even over bumps and stuff, so maybe I shouldn't be worried. How much (on average) do you think a shop may charge for this?

Why would you do this?

What do you think you will gain?

Alot of people do this because the over the axle part of the cat back is almost half of a circle. The flow is much better under the axle. Manny has pictures posted take a look this is very common with people with turbo set-ups.

You may scrape but thats a risk you will take. If you get a small exhaust your are less likely to scrape than with a 3''. I believe Manny had 3'' clearance with his 3'' exhaust, correct me if I'm wrong.

Bottom line: yes you can do it, yes it'll increase your risk of scraping, but just be careful.
