I have a Powerflow on my FRP and its the dogs danglies...no problems so far, I have had it on about 2.5 months. Sounds great too. smile.gif

They come with a lifetime guarantee, so if there are any probs take it back

Second Lisa on the Powerflow exhaust- well worth the money and you get a choice of tailpipes.

Most other aftermarket systems are too quiet and are for sissies ;-)

My kat is going in for a new system in three weeks. I have decided to go with Hayward & Scott exhaust.

I am having a twin system put in with a pipe either side that should look loooovely with the Stoffler rear valance. Think I might go with 4" slash cut ends, 4.5" would look too big me thinks.

Will see in three weeks what their efforts have created, ready to show off at 'Big Essex Meet 2 (bowling)'

I have heard the Mongoose system is quite popular.

Right, couple of points on exhausts and mutli cylinder engines.

After market exhausts fall into two camps

1. The "performance pipe"

2. The "max power pipe"

Very rarely will the two actually combine to give a really good sound, and improvements in breathing.

In general, a Twin pipe system will actually take several BHP away from the engine, as part of the art of exhaust designing is in creating the constant "pull" of exhaust from the engine. This is normally achieved in the down pipe, and the way that the four pipes blend into one final run. By setting the join length from the outlet to the join, and the radius of the down pipe curve to match the outflow characteristics of the head, more power can be wrenched from the engine.

The problem now is that most aftermarket exhausts are "cat back" systems, which cannot therefore have any real "tuning" effect on the engine, other than to open up the bore once passed the cat, (which will create a low pressure area of sorts)

A true tuned performance exhaust would consist of a complete system, including downpipe and cat. These however are extortionate, and on a NA car, simply arent worth the cash.

Max Power systems for want of a better word, tend to work on the ears moreso than the engine, in the way that they sound.

The best example of a Max Power exhaust is probably the one that is fitted as standard to the FRaPy, which is kinked to cause the trade mark crackle...

Ford Racing say the crackle is made louder by the use of a freer-flowing tubular welded manifold rather than the cast one found on a standard Puma.

I say louder because according to them, the standard 1.7 DOES crackle, albeit very quietly as the sound is trapped within the cast manifold whearas the tubular one allows the sound to resonate and 'escape'.

Replacing the standard restrictive back box on an FRP lets the sound exit the tailpipe and sounds spectacular! ohmy.gif)

Prices vary widely- for a back box I've seen prices between £80 to £260.

I've recently had my exhaust altered, but it was based upon the standard (one-piece :twisted: ) item.
We've opened up the original mufflers, wich are already of the absorbtion-type, and removed all of the damping material.
The back box also lost the rear pipes in the box so that you get a nice big chamber in the back, and following we welded on a 100mm round pipe (with muffler included in the pipe)

Sounds great, looks the biz, and it makes your puma a lot livelier...

A very cost-effective way to get a fruity exhaust note, and on top of that, you don't have to fear the inspection, because all of the welding traces are on the top side of the boxes...

Hope this gives an answer
