Exhaust Noise

[Bytes]

Hi, I've recently had my Kakimoto GT 1.0z Titanium Exhaust noise tested at Brands Hatch and it failed at 113.4db near 6000rpm.

I'm after short and long term suggestions about what I can do next. The exhaust is a one piece unit so the back box is not removable.

In the short term I wanted to take part in the taster sessions at Brands on August 5th. Would a bung or baffle do the job? Is there anything to worry about when using one of these and driving a car fairly hard round a track?

In the long term, I'm after suggestions for a quieter exhaust for my V4 classic.





Thanks

Neil at Slowboy (atleast i think it was Neil) recommended I didn't drive car hard with bung in.

I have a japspeed flanged 2.5 inch back box you can borrow if you can source a loan middle section to put on.

I had similar advice from JGM on the hawk. Fine for day to day but dont go tracking it!!

Yes, I thought I'd read something similar about the bung/baffle idea

Powerflow in Ashford could weld in a silencer

I have a full 3" fujitsubo fgk giken exhaust if any good??

Revolution exhaust system wins on track every time on value for money

Thanks for the suggestions and offers (bonner) - I'll bear these in mind when I decide what to do

My Kakimoto came off the Evo Friday... So nice to be able to hear myself think now... Screamer pipe off tomorrow

I've been offered a complete 3" Hayward & Scott slip jointed decat system for £250. Any thoughts on price or performance? I can't find slip jointed parts on the H&S website so is this an older system? Thanks in advance.

that certainly looks right for an H&S by the style of the rear box and hangers..............

v.good system

[Scott.T]

Not sure that's H&S.
As Alyn said the hangers look H&S but they don't tend to weld the pipes together in sections as the above has just on front of the backbox. Instead they mandrel bend them.

I have never known them to do a slip jointed system and I bought my first H&S product back in 2001 when they first started Scooby backboxes. They have always had the much easier to install/remove flange fitments.

Revolution do a 3" slip jointed system which I believe was/is made by Mongoose, but I've never seen one off the car, so not sure what hangers it uses. These are good systems but a fair bit cheaper new then the equivalent H&S.

Thanks for the info guys ... looks like I'll need to ask some more questions

Thanks Alyn. I wasn't quite sure.
Mongoose, Scorpion (who I think made the Prodrive Box and also the TSL Grp'N'), Magnex and even Scoobyworld/H&S can all be a bit incestuous.

Although some of the above 'Brands' no longer exist.

Do Tube Torque still exist. They used to be big of Fords, as had a nice system on my Series 1 Turbo years back......

thinking about the pic it may be a Mongoose??

[Hongkongfooi]

What exhaust would you recommend then Alan for a bit quieter? My tsl is too loud

[Bytes]

So if it is a Mongoose or Revolution is £250 now overpriced? I'm also presuming it would be quieter than my present system
